BS, or anyone, Power tilt problem

[macojoe]

Ok who knows about power tilt and trims??

1988 Yamaha 175 hp, Model 175ETXG Serial 751765

I had the dam left pistion cab come lose again!! low on oil, and tryed to get it up, but no go, So I lifted it to assist with the eletric.

After getting it home I retighten the cap and added fluid, keep going up and down till the fluid stays full (per book for bleeding)

Now it goes up and down but when up falls back down slowly.
I have drained all oil cause it looked like it might have had water in it??
But after draining all oil and refilling I still have the same problem, and when I unscrew the fill screw it lets a lot of air out, and the oil looks foamed with air in it.

So I must have some kind of internal leak?? But what and wear to look??
I am running real tight on cash and would like to try to hit the nail on the head, to save rebuilding the whole thing!!

Thanks all!!

Internal leak. *There is a bad valve or seal in the pump that is allowing fluid to leak back into the reservoir. *Nothing too horrible, but it will require a rebuild of the pump. *Feeling handy?

For us Volvo guys, there is a valve housing that would have to be replaced. *Throw on some new o-rings and you should be good as new. *The pump itself rarely wears out.

I don't know where to find microfilms for the Yamahas, so I can't tell you exactly what you need to do.

[macojoe]

I can do it!!
And I have some friends to help, it don't scare me!! ;)

The hardest part will be removing the whole assembly from the motor,

But I did it 2 years ago to repaint the trim motor cause it was all rusted.

So it will be easy in the way as I have done it before, and when I reassambled it I used antisizen all the bolts.

I just want to make sure that the problem is the pump, or motor, ect ect.. *Before I go off half cocked!

Thanks Skools!! I put in my watch list, but I don't think I can afford it right now :(

I have a B-Day coming in July, maybe I can get some early donations ?? ::)

[macojoe]

well thats what CB and I have thought, I am going to give it one more shot!!

My wife said I could buy the ebay one ;D I am watching were its going, see what happens??

I will let you know what happens

[macojoe]

Does anyone know if that 115 V4, will fit my 175 ??

I have someone tell me its not going to work cause it is different??

It does have a different part number, but look excatly the same??

[Skools Out]

Mj i know on the V4 and V6 John/Rude ones they have a different part number but they are the same only difference is the bushing in the tilt arm where the pin from the motor is different size. In those you just have to put V6 bushings in a V4 unit to work in a V6 or do the opposite to fit a V4.

[macojoe]

I think I am going to buy it!! Can't be all that much different!!
Looks the excat same, I was thinking that maybe the center ram was a little shorter?

O well the auction is over tomorrow some time and I am watching like a Hawk! Hope it doest go up much ::)

CB, also sent me a advertized 1981 Yamaha 175 like mine (mine 1988) thwe guy said he attentions of fixing it up for a Mako he had, but has not had the time and what not.
Said the hole motor is FREE for the taking, just come get it!!

I emailed the guy and waiting to see if he gets back to me??

[macojoe]

Wellm the free motor is gone, I was to lte :(

O well the ebay tilt goes off tonight, lets see if I have any better luck there??

[macojoe]

Loss the bid *>:( *was at $260 and in the last 5 sec I bid $300 but the other guy already had a higher bid waiting.

They have another one going off in 4 days, $199 right now, but says its for 95 and up?? I will have to see if it will fit??

Did you try bleeding the system again?

To get the air out . . . Tilt the motor down all the way . . . loosen the relief screw a few turns. Have one of you kids put pressure on the lower unit while your trying to tilt the motor up. The cylinder should fart out some air bubbles/fluid (out the relief valve) When it starts to lift them off the ground and stops farting air bubbles tighten the relief valve. Continue to tilt until the reservoir sounds like it running dry . . . then stop put more fluid in the reservoir and continue to tilt the motor all the way up.

You could also make an offer of $200 to this guy . . . . but I'd go with the parts motor if you can get it for cheap!!

[macojoe]

Thanks BS!! *

Yes I have tryed to bleed again, but the relife screw is frozen in place *>:(

I have been told that the relife on these Yamahas have been a problem and thats were my problem is??

Also was told by the guys at Nauset Marine that a rebuild kit is 200+ and that they no do it as they have never had any luck with a rebuild before?
They said thwere is someone offering rebuilts now and that they get $500+ for them, They ordered one and are going to see how it turns out?

I am going to watch the parts motor, and see what happens?

I am going Mackrel Monday and after that I might try to pull the release vaul out and replace the o rings and see if that the problem?

It will be good to have the parts motor no matter what, so I will be watching!!

Thanks!

[bigshrimpin]

MJ - Can't you drill out the relief screw and buy another one? or retap it and use a standard size screw.

[macojoe]

Ok I am all fixed!! ;D

After talking two everyone in the world, 99% said they thought it was the relife screw leaking by?

But it doesn't move I tell everyone?? I talked to a old time yamaha guy and he said that he had one that did not move eaither and it was that screw that was causing the problem.

I guess when the O ring was new it did not need that much tightening, And after years has worn some.

When I was at my brothers I tryed to lift the motor by hand as it was low on fluid, When all of the sudden it poped like something broke and went up.

Well today I went out there with a flat screw driver bit for a 1/2" impac wrench.
Put on the screw and 3 good hits with the hammer and the screw broke free!

I sprayed with PB Blaster and worked it back and forth back and fourth a bunch of times.

before it broke lose it was at lets say 3:00 position, when all was done it was at the 5:00 position and the thing works great!!

No more leaking of any kind. To think I almost spent $300 on ebay yesterday :o

But I am watxching the parts motor, I want it for all its parts!

Thanks ALL!!!!!!!!! Now Its time to start fishing! ;D :D ;) :)

[phester]

there are few better feelings than having a problem [especially on the boat], diagnosing, and repairing it yourself....and it working like new. Not to mention the 3,4,5,600.00$ hit you would take if you had to have the repair done for you. Good job MJ !!

[bigshrimpin]

Just got this response from the ebay guy. You best jump on this motor before it goes bu-bye. The cowling/prop will net you $200 on ebay. That's a free spare lower unit, trim and tilt, oil tank, etc., etc. !!!

Q: 200 and it's yours...i had it listed for 300 but don't have time to mess with it..let me know before i get more bids..i have 35 people watching it

[Blue_Runner]

Dang it BS!! I was gonna cheat MJ outta that oil tank for peanuts!! Now you've **** blocked me!!

Naw, I don't really need it. The only reason I'd buy it would be to help sell my '94 150 which has neither oil tank or prop.

But you are correct in that you could get a pretty penny just for the parts. Hey and that cowling - she looks good. You should be able to get $100 or better just for it!

[bigshrimpin]

I'm sure MJ will hook you up. He was Hummin and Haw'n about buying it for $200.

MJ - You've got 7 hours before this guy won't be able to end the auction!!!! You know the Trim and Tilt alone is worth close to $300!!!!!!! Get on it!!!! If you don't I'm sending my dad over to pick it up . . . he lives in Bedford, MA.

[macojoe]

Ok Ok Ok I bought the motor!! and not only did I get it for $200 its being delivered to the Cape for me to pick up ;D

So I have a bunch of parts for sal for anyone who may need them!!

Blue if you need the tank I will make you a deal!! Just let me know!

Some of the stuff is going to find its way to ebay, So speak up before they do!!

Thanks BS!!

[bigshrimpin]

MJ - You just got the best deal ever!!!! Nice Work!!

[Blue_Runner]

MJ, thanks for the offer but I was really just in this for the comedic value :-)

Make your money back on eBay! You shouldn't have any trouble at all. Hey and if that cowling is in better shape than yours, swap that baby out!

If you sold everything you could make your $200 back and probably 4 or 5 hundred to boot! Or just keep whatever backup parts you think you might need later and sell the rest.

Good luck. Whatta deal! You the DAWG now!! ;)
