Guess who was TOWED in today ??

[macojoe]

Me, >:(

After the last run, I drained the tanks, new fuel, new gas filter, new plugs, all for nothing!!

Got to the ramp. Started right up!! Took off slow, motor was shaking more then normal??
After getting thur the no wake zone I hit the gas.

Right up on plain and going great!! For 3 min, then it slowed down and staled when I powered down.

After that it wouldn't even turn over??

I pulled the cover, looking at the motoir from the inside of the boat, the right head was so dam hot I couldn't even touch it!!
But the left head was luke warm??

threw anchor and started fishing right there, nothing!! >:(

so flaged a guy down and he towed me in, Nice guys!!

Well after I got home, I took the termostats out and they both seem to work fine??
I am going to change them any way.

the plugs are brand new and they look very dry and white?? No sign of oil??

read the book to see how to ck the oil pump, after trying to remove the arm that controls the oil , the bottom of the oil pump fell out?

There is a small break on the end of the oil cam. We did use oil on the way out, cause I did ck it before leaving, and when we returned it was down about 1/4 inch.

the motor now spins like it should with no problems, so I hope I did not ruin anything??

Now I have no idea what is doing this? But I am getting that parts motor tue, or wed and I will swap out the oil pump and see what happens??

I am not having a good year!!

Can any one else think of what else to try??

Think I shoulkd pull the head on the hot side to see if anything is bad??

If the head or cylinder is scorn, and I fix the oil and stuff think it will work??

[Hammerhead]

*If it's a two cycle with the auto mix feature.... disconnect it and start mixing the gas yourself. *My ol'115 'Rude and a Yammie 90 I have now a had the oil dealio disconnected at my wenchs insistance.

Mix some oil and gas yourself and run the thing. watch and listen for unsual noise or smoke. Outboards are generally very tough motors and hard to kill.

[macojoe]

I did disconnect before and tryed mixing, but my plugs got fouled every 3rd trip!!

And i mixed it perfect 50:1 evey time!!

[Hammerhead]

I always use 87octane and add some Yamaha ring free about every 40 hours. The lower octane burns cleaner and the ring free cleans the carbon out. Good Luck whatever ya do.

[macojoe]

I use 87 and seafoam a couple of times a year, it will keep the carbon at bay, Yamaha loves carbon.

[reelapeelin]

MJ, that's a real BUMMER!! :P ...wish I had some good suggestions...sounds like you been maintainin' good...I's thinkin' the same as Hammerhead about discoin' the auto-oiler and mixin', but that probably wouldn't affect only one side...wishin' ya luck whatever it is... ;) :)...

[phester]

was your pee indicator pee-ing?

[Skools Out]

does it have direct oil inject? may have a bad oil injector i had one go bad and killed a cylinder. Check your compression and post the readings please. that will help alot too. I'd run light mixed gas and some Marvel Mystery Oil in each tank right now too. it will loosen up any tightness the heat and lack of oil caused.

[Stinky_Hooker]

Man MJ. I am truely sorry bro...that'll rip your heart out and stomp on it. :'(


There are few things that are more frustrating than a broken down outboard....IMO :P

[76GMC1500]

It's a 2 stroke, it's so easy to pull the head there is no reason not to do it, except the cost of head gaskets. It's good to exercise the bolts every once in a while so they don't seize up in the block.

[bigshrimpin]

MJ - It's not sounding good. Check the compression . . .just like skool's said. That'll should tell you want's up. If a cylinder is low on that side then yank the head off and check it out.

[msbhammer]

Mac:
Sorry to hear about a bad day on the water. I got faith in ya Brother !!, you will be back out soon.
Hoping to sneak in a quick ride today if I find a longer control arm. If I make it out, I joined Tow Boat U.S. just in case if I run into problems myself.
Keep us posted on what you find out.

[Blue_Runner]

Definitely check the compression before pulling the head.

BUMMER! I have to applaud you for being able to take pictures during such an ordeal. I'd be too pissed and my camera would probably be on the bottom of the bay >:(

The good news is that whatever this problem is, you have a bunch of guys on here that can help you out. I just hope your compression is still up there. If not, wonder if the powerhead on the parts motor is up to snuff?

[macojoe]

Thanks all!!

I will be doing a compression test later today, that should tell weather I can salvage the season or not??

As for the part motor, it has one bad cyl in it.

What I am hopping for is that I can get my motor to limp along for this season, and maybe rebuild the parts motor over the summer and winter. Then in the spring swap out the motors??

As for the pic, I look at it this way, yell scream and cry and in the end the motior is still broke or fo with the flow, I went with the flow!!

Heck I fell asleep across the rear deck for 1/2 hour while my buddy casted for some fish , He got none.

He woke me up when he waved a guy down to tow us home ;)

[76GMC1500]

Excessive blowby can heat up a piston and cause it to seize so be careful running a motor with a gimp cylinder.

[macojoe]

Its offical!! I am F-cked, No fishing for me this year!! >:( :'(

[Blue_Runner]

:o>:( :( :-/ :'(

DANG MAN I HATE THAT FOR YOU!! Not trying to make light of your situation, but I do remember you saying you wanted to take up surf fishing. I guess you could still fish if you so desired.

That is the worst possible news ever. No boat owner ever wants that!

Sorry MJ!

[Blue_Runner]

MJ I have a '94 150 Yami. *I'll make a good deal for you. *

It needs a carb job and I haven't started it in 10 months. *I took pictures showing it running at that time. *It would idle good as long as RPM's didn't go below 800. *Compression check showed decent compression. *Also, wasn't getting max RPMS. *Only about 4400, or maybe it was 4800? *Probably due to carbs? *Pushed my V21 to about 35ish best I remember. *

No prop or oil tank, but I think you got that covered. *You need to part out your motor as well as the parts motor you just got and buy this one from me for $1200. *Look up the old post in the FS section for pics and info. *I think I took the pics and stuff and posted some time around July of last year. *The exterior cosmetics aren't so good on the cowl, but underneath she is very very clean. *Also lower unit looks to be newer than the rest.

Just something to think about. *Could probably get it shipped up for $150 - $200 or something.

Let me know if I can help a brother out! *I just about put it on eBay the other day, but want to put my old V20 up at the same time and still haven't got the pix of it yet (I'm lazy at selling stuff).

Compression numbers a true BUMMER...talk about a LEEMP DEEQUE, but MJ...you fell asleep after your motor went out?!!...

OK everybody, who's up for givin' MJ the MEGA-NORTON Award for Confidence!!...Vote HERE:

RAP votes YES

[Skools Out]

MJ that sucks major I like BR's offer. I've seen the motor looks great and you'd be in bizness in no time. I bet your motor would part out for what BR is asking for his ??? What's the difference in the 175 you have and BR's 150? Will your reeds and carbs fit BR's motor and make his a 175? the cheapest shipping company is by far i've found www.freightcenter.com Just shipped Boater93's 225 from Mi to NC for $224.90.

[macojoe]

After crying all day I am now getting excited again!!

Do you think that 175 carbs will fit 150??

this is a question for BS!! I am real interested!!! But can you hold a bit longer??

I have to sell some things to come up with the cash.

you guys are great!!

I just may have a new bo, cb's out now!!

[chumbucket]

175 Carbs WILL fit the 150 8)

[macojoe]

CB will they go from 88 to 94??

[macojoe]

what model is that motor BR??

I just went to a site and looked up mine and got the carb number, then looked up yours, they have 3 different models,
so I picked one at random, thinking that they probly all the same any way, and they matched!!

[Mac_Attack]

MJ sorry to hear your bad news. I sure good things are about to happen! Bill Mc ;D

[Skools Out]

check reeds too you may need the 175 reed cages and reeds to make from 150 to 175 that's what an OMC changes

MJ - Looky here . . . You have two of these. They're a little older . . . still should be worth something.

[macojoe]

Thanks BS, But after talking to few macihinic's I think that a rebuild by myself is out of the question!

I am going to try to work a deal with BR and get his motor here.

I checked and the carbs are the same numbers, I just don't know about the reeds??

But with all the parts I have for sale, I could make the cash, buy his fix the carbs, and be in ther water in short order!!

And best of all my boat is all rigged for his motor, just bolt and go.

[Skools Out]

i'd suggest premixed next motor. i've learned that plugs are cheaper than powerheads. pull the head off that side post a pic of the bad cylinder. you might be able to do a 1 hole fix. They really aren't near as hard to fix as shops want you to think. if it's very very light scoring just hone out the scratches put a new piston kit in that hole. rod should be still good.

[Skools Out]

MJ if i were closer to ya i'd say send the power head over and i'd pop a piston it her for ya and re-ring her.

[bigshrimpin]

The carbs should bolt up . . . It's probably better just to use the 150 carbs . . . clean them real good and get rebuild kits.

There are a lot of parts to make a 150 into a 175 . . . besides just the carbs. I'm not totally familiar with the mods for the Yamaha Blocks and the differences b/w the model years. You could always compare the part numbers.

Usually it's the carbs, reeds, heads, exhaust that tune the motor. The block is usually the same . . . Some Merc's have a horizontal front half and others had a verticle front half. Motors with a horizontal front half usually produce more HP. I think the same is true with the Yamaha 2.6 excel/220special and the regular block. Just ask around screamandfly.com or byuboyz.com . . . those sites are full of good info for a rainy day when your not going fishing.

Just compare the parts

Since you have nothing to lose, pull the head and take pictures. Make sure the piston is still there. It may be something as simple as broken rings on that piston. A quick hone and some new rings and you'll be good to go.

[bigshrimpin]

Hone and swap a piston out from the parts motor.

The pic shows head gaskets in the set.

[bigshrimpin]

I still think BR's motta is a better move, but you got nothing to lose by taking the head off or tearing down the whole motor. It's the best learning experience if you've never pulled one apart.

[reelapeelin]

Skools, ya think w/ "0" compression it could be only minor damage in that cylinder?... ???...

[Blue_Runner]

Let me dig up that old post with the pics and specifics about my motor...

And yes, I'll hold onto it for a while - its been 10 months already!! ::)

[Blue_Runner]

Found some old posts that show the motor and give all of the details...

As you can see, I originally wanted alot more than $1200!! But at this point, I'll take a win-win if I can help MJ out PLUS get this thing outta my yard!

MJ, the negative points I see about this motor are:

1) That shift rod issue. I don't think this one has been replaced and as you can see, there's a fair amount of rust in that vicinity.
2) The weak turnover at startup. When you hit the key there's a 1 or 2 second hesitation, then starts to spin as normal. Most likely just the starter ???
3) Sitting 10 months under a tarp.

What about UPS'ing your head to Skools and let him fix that piston? There's a thought. Either way, we are here to help a brother out! I was looking forward to seeing those fluke pics again this year :'(

If you want to talk by phone, PM me and I'll give you my #. Or, PM me your number and I'll call you from my work phone and it won't cost us anything! (I'm a cheap bastard :D).

[Skools Out]

with 0 compression it is most likely major. usually when you have a ring break only it will still have compression around 30 or so psi. With 0 i'd say not to good. take the head off lets see if the walls are to bad to just hone. if it needs a bore job you'd need to bore all to be same on balance of the motor. to bore them all and buy oversized piston kit for motor plus gasket set. it would be better to part out motor and buy BR's.

[macojoe]

Thanks guys!!

I think my motor is to far gone to bother with, and the cost to make it better is not worth it to me.

As for your motor, I have full set of working carbs and reeds, I looked up the parts and they are the same number.

As for the shifting rod, I have a 4 year old one in mine that is stainless, that I had put in right after I got the motor.

Slow start?? I have 2 starters here for it,if t6hats the problem??


So it seems best to go with your deal then to stay with mine.

I have never done a shift rod, and I know it means pulling the power head, But I know for a fact that BS did his with his dad in the yard and it wasn't all that bad.

So I am sure that I can handle that.

I think I am going to stick with yours as my best option for the moment.

[Blue_Runner]

MJ, its here and its not going anywhere. ;)

I'm in a big mess right now remodeling my house, but if I can find the time, I'll see about doing another compression check to make sure nothing has changed in the last 10 months.

[chumbucket]

BR's motor should have a stainless steel shift rod from the factory if I'm not mistaken. I think they made that change somewhere around '92 or thereabout.

[bigshrimpin]

CB's right . . . 1993 was the first year of the stainless shift rod.

[Geekie1]

MJ, Sorry to hear about your problem. I think the problem could be a burned piston. (hole in it) You can burn a hole in a piston if you get crud blocking a circuit in a carb causing the motor to run lean. Also the float needle seat getting clogged will definitely cause a lean condition. Running lean causes the piston to overheat burning a hole in it. If I were you I would pull the head to check the piston. It may be possible that you can replace just the piston and rings. If the piston has a hole in it, the center carb feeding the cylinder would most likely have caused the problem. If you replace the piston, pull the carbs clean and rebuild them. Check the center carb especially!!

Did you say that the bottom of the oil pump fell off?? If that was so then there should have been oil all over the lower cowel on the starboard (right) side. (looking back at the engine) Lack of oil would cause so much damage to bearings and crankshaft that the engine would probably seize permanently and the engine would not turn over even after cooling. The power head would definately be junk.

I would pull the head to check the cylinder out in any case!!!

[76GMC1500]

You can hone the cylinder yourself using a ball hone available at your better automotive parts stores. Hole in the piston is a common 2-stroke ailment and is sometimes easily repaired. It would also explain your hot bank.

[Skools Out]

a ball hone is what you need after using a standard flat hone. the ball hone will not keep the hole round like the flat hone will, but must run a ball hone in both directions to take the birs off the ports in the cylinder walls.

[Blue_Runner]

;)
Skools is right - my old lady honed my head last night and THEN used the ball hone. It was out of site!! :o

[macojoe]

Thanks all!! For your suggestions!!

But I have not the tools or the no how to repair this motor!! Its a total loss as far as I am concerned.

The cost of a machine shop, and parts, and then the rebuild is alot to gamble on if it doesn't work out!

I think BR has a good motor there!! I think a good Decarb will bring the comperssion numbers as Yamaha is none to carbon up alot!

That might be all it needs?? As for the starter issue I have 2 that are good right here.

Shifting rod is Stainless in the first year Saltwater Series from Yamaha, and I have a 4 year ols stainless from my motor if its not.

My carbs are the same number as his.

And best of all My boat is all rigged for his motor already!! We have the same controls, wire harness, steering, shift and throttle cables.
I already have the same oil tank and its installed with all lines.

from the time we start to finish I bet that motor will be bolted on and runing in a hour!!

Once again Thanks all!! If anyone has a need for parts from a 150 to 200 yamaha from 84 to 89 and beyond just let me know!! I have 2 of everything!!
