Yamaha Oil Injection System

[Seakindly]

Recently, I have learned a bit about yamaha's oil injection system.

This link was very informative:

[chumbucket]

Good link. Thanks ;)

[Seakindly]

CB, what's with the winky ???
Don't tell me you alread posted that link on this site. :o

[macojoe]

He's just that kind of fellow!! ;)

[macojoe]

Thanks Seakindly for the fine read!!
I have been having a problem with overflowing! and have not figured it out
I have been told by a few that it is the float switch in the main tank?? I have been told by a yamaha guy that it is the control unit??
But this articale says if the Cap on the main tank is not aligned it coud do this also?? I had it off at one point and don't ever remember lineing the Arrows up?? Could it be that simple?? Not for me!! But I am going to check.

Thanks again!!

[chumbucket]

No, I didn't post already. I just thought it was a good article. I usually reserve my winkies and kisses for MJ. :-*

Seakindly,
Thanks for posting the link . . . this is a great article.

[Seakindly]

Macojoe, To test the shut off float switch on the engine oil tank, all you have to do is take the float assembly out of the tank and remove the strainer - then slide the float all the way up. if the upper float switch is working correctly - the remote tank pump will stop. If you slide it all the way down then alarms go off. at an in between position - a switch tells the remote pump to pump.

When you put the float assembly back in the tank, make sure the arrow and notches line up. The outlet nipple on the float switch/strainer assembly must sit in the very bottom of the tank outlet hole or else the float can bind. You can feel that it is in the groove by wiggleing it side to side. Good luck!

[Seakindly]

Also, if this works for you, don't forget to bleed the air out of the system, after you refill the tank, before you run the motor. :o

[Seakindly]

A good idea for anyone with a yammie:

Print out that article (no telling how long that link will last), and staple it to the inside back cover of your service manual.

[Seakindly]

MACOJOE, One more thing. My quick test will only tell you if the float system and control module are functional. If your float system fails my quick test, then the next step is to properly test the float switches, as per the article. If it passes the proper test, then you must then look to the control module and the mercury switch. Let us know how you make out.

[macojoe]

Well i went out side to day and pulled the cover off.
The arrows were NOT alingned. I pulled it out and took a look and put it back with the arrows in alinment.
Is this my problem?? I will not no till the spring when I can start the boat and find out.
I want to be ready early this up comming year, so I will pul the cover off in march and start working on it.
Thanks Seakindly!!
I am going to print this Topic and that articale. And I am sure that there wille pleanty of talk come spring.
I can't get that lucky with just having to aling the arrows??

[Seakindly]

Macojoe, reread my post above.

All you need to do is turn your ignition key to the on position. Take the float assembly out . Remove the strainer filter. Slide the float up and down the shaft. Listen to the pump to see if it comes on and off when it is supposed to. You don't need to have any oil in the system or start your motor to see if it was only a missaligned float that caused your problem.

* You MAY need to have the remote tank at least half full for the pump to come on, but you don't need oil anywhere else for the pump to work. If you drained the remote tank when you disabled the system - the pump will/should come on automatically for 180 seconds to fill the engine oil tank to the correct level.

[Seakindly]

MACOJOE?

[macojoe]

Yes?? How can I help you??

[chumbucket]

You've got to bear with him Seakindly. He was probably standing too close to the microwave oven again. ;D

[macojoe]

:o Who me ??? He said Hey Maco and i am answering him ???

[chumbucket]

;D :-*

[Seakindly]

I just wanted to know if it was time to sell my stock in the YAMAHA SPARK PLUG MANUFACTURING CORPORATION, or should I hold my shares in anticipation of another year of record breaking sales in the American Northeast?

[macojoe]

You may be right!! I have not had the chance to get out there. The boat is all covered and there is no batterys in the boat eaither.
It would be a major project just to get into the thing!! So i will be waiting till March some time to do the test.
But I have printed this thread and the site you sended me to. So I have all the info at my finger tips when the time is right.

I will keep all informed when I do it. This way you all can learn by my mistakes!! ;D

[macojoe]

Ok time to bring this thread out of moth balls!!

I went out and started to play with the injection system today.
Ok I took the float switch out of the oil tank on engin. Slid it to the bottom and the alarm went off. And oil did pump into tank from remote tank.
Now does anyone no if when the float is moved back to the full position, if the alarm shuts off??
Mine will not shut off until I turn off key and then turn it back on?? Sort of like a reset??
The manule I have does not say anyhing about this??

[bigshrimpin]

MJ - That's a good question to ask that guy you bought your engine from. He'd know off the top of his head. Anyway . . . you might want to look into getting the yamaha service manual for your engine.

One on ebay just went for $5.00

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2476385578&catego ry=50439#ebayphotohosting

[Seakindly]

MJ, yes you must reset by turning the key off, then back on. In addition to the warning light and buzzer, the engine RPM drops to 2000, Unless you reset, the RPM won't go above 2000, even when enuff oil has been added.

Sounds like another problem solved. :)

BTW, my boat is way overdue for a waxing. ;)

[macojoe]

BS, He is gone!! Moved the whole shop to Florida!! So he isn't going to be of anymore help to us. :(

I just finished installing that 25 gal gas tank also!! Thanks again!!
But can you help me one more time with that tank??? I now carry 65 gal gas at $2.00 + I need $130.00 cash
to fill the boat :)

I also have a Claymer manual and it does not mention weather or not if you need to reset.

Thanks Seakindly! It seems all to be working and all I need to do is get the dam thing in the water!! That will be the test!!
I have to wait till next week. I should be getting trailer parts any day now and then I can get going. Not to mention I am still working 2 jobs till this Thursday!!

Thanks guys!!

[chumbucket]

I know mine also requires turning the key off, then on again to reset. Glad you got things working Bud.
Dad's back home from the hospital so I'll have some more free time instead of driving into Boston everyday (twice on workdays. :-/)

LETS FISH!!!!!!!!!!!!! ;D

[Seakindly]

OH, MJ -- I said it before, but I'll say it again.

MAKE SURE YOU BLEED THE AIR OUT OF YOUR OIL LINE BEFORE YOU RUN YOUR MOTOR. 8)

[Seakindly]

CB -- I didn't know your dad was hospitalized. I hope he's OK, now.

[macojoe]

Thats good news CB!! I hope to get the boat all set by the end of this coming weekend!!
Then I have time for fishing!! I am down to one job now!! ;D

I bleed the line already, but thanks for reminding me! Some times my Altimzers gets to me ::)

[chumbucket]

Some times my Altimzers gets to me *
Yeah, and sometimes the spelling gets to ya too! ;D

Yeah, Dad was hospitalized for about a week. He had a mild heart attack, actually a little while before the hospitalization. He was experiencing some more pains, so they admitted him and did a Cardiac Catheterization. He's doing well now. Thanks. I told him he can't be down now with the fishing season about to get into full swing. ;)

MJ, you must be glad to be rid of that other job now. Money's good, but that was going to cramp your style once fishing starts.
I'll give you a buzz in the next day or two. ;)

[Seakindly]

Yeah CB ... he can't let a little ol heart attack get in the way of his fishin.

My dad's already had 3 heart attacks, and it doesn't stop him from doing what he loves to do ... chainsmokin ::)

[macojoe]

But I am still having problems with the oil injection system??? Last year it kept over flowing and Jef thought it was the control box. But there was a thread posted on this board that lead me to a Yamaha trouble shotting site.
I went there and they said to ck to see if the arrows were lined up on the oil tank and float cover. They were not!! I alinged them and all seem to be well.
Its not dumping oil in the air box now but it is pushing the oil float cover off the tank???

I boats said to ck the vent that it might be pluged?? So I did. And it is clear!! I blew air thur it.
put back toghter and it still does it??

Other then this the injection is working perfect!! But I am baffled??

Anyone have any other Ideas??

Later

[bigshrimpin]

MJ - Let me see if I understand you . . . Too much oil is being pumped into the remote reservoir (little oil tank under the cowling) causing it to overflow and somehow the sensor isn't turning off the pump.

1. Could the Cap with the oil level sersor be coming loose i.e. not seating properly around the mouth of the oil reservoir?

2. Or the sensor/float/switch is busted (part 24)?

24 6E5-85730-13-00 OIL LEVEL GAUGE ASSY 1

That would be my guess?

:-/

[macojoe]

Well not sure what it is?? I went to I Boats and they say it sounds like a blocked vent.

I blew air thur it and it is clear.

I am thinking that you are close in saying the cover is fitting to lose? The seal just might be to worn around the cover?

I am wondering if I can get just a seal or have to buy a whole new part 24??

I have been so busy that I just said the heck with itfor now!! It does not leak oil, Just pushes the cover off and you may see a little oil, but nothing to speak of.

[macojoe]

This is a response I got from IBoats

hello
what is happening is when the oil transfer occurs the engine tank cant vent or the float does not shut off the oil transfer. the resulting pressure in the engine tank can push the float assy out of the tank. if you remove the float assy and the filter screen and drain the oil tank you will find a rubber seal between the filter screen and the tank. the seal should be replaced or at least retrived everytine the filter assy is removed. the filter assy has a hole at the top that must line up over the flat on the float assy. if it does not the transfer may not shut off proerly.
good luck and keep posting

---------------------------------------------------------------------

My book does not mention this seal?? were does it go, I belive that it goeas on the nipple on the bottom of the filter screen?

When I put the filter screen back in I move it till it falls into a hole, is this right?? Then I put the float in making sure the arrows are alined.

I am sure I am doing something so small but it is making a big problem.

MJ - The link above is the online yamaha parts catalog. Maybe ask Iboats guy to ID which part he is talking about.

either way . . . It's a multiple choice question: :)

1. either the cap is worn out
or
2. the float is busted
or
3. the vent is plugged up causing enough pressure to "pop" it out.

Now it's just process of elimination. You might try running the engine at the dock with the cowling off and watch to see if the top "pops". ;)

You can always use Plan B and rip the oil injection right off and use premix.

[macojoe]

All fixed!!! It was the float switch part #24

I was getting sick of the oil slick I was leaving and called for thew parts. Online it was $158 + Shipping Here it was $187 I bought here for two reasons , one I wanted it yesterday!! And two I was not sure which part it was and he only had the float and would have to order the other part. So I did the float first.

Any who ran all around Chatam today and not one drop in the water!! ;D

Thanks All for your help!!

[chumbucket]

That was the only way anybody followed you to your spots. Just follow the slick.
"Oh look, MJ was here." ;D
Good thing the "Green Police" didn't follow that slick. You could tell them, it must be the remains of that tanker that went aground. ;)

[bigshrimpin]

Good Work MJ!!
How many keepers have you been getting out of chatham? I'm coming back to MA again Aug 14 - Aug 23 . . . you'll have to fill me in on the fishing.

[macojoe]

If you get there first thing in the am and have FRESH, FRESH Sand eels you can get between 5 and 10 commercial keepers.
Paying like $1.50 per pound

Rec Keepers, all!! They are all keepers!! I have been going there with some buddys and have taken a few charters out there and this is why i have senpt a long time there this year.

The fluking at Vinyard is in a sad sad state this year!!

Let us no when you are in town!! you me and CB well have to go do a Bass or what ever trip!

[bigshrimpin]

MJ - What's up with the Fluke? Are there too many people fishing for them? or are they just not there in the numbers?

I don't no who is catching but its not me!! Was there Thur a commercial day and there was like no one there?? And no fish??

[bigshrimpin]

The full moon tides have always been tough for me. First hour seems ok, but after that the current is just too fast especially when the wind is blowing in the same direction as the tide. Sometimes I've had good luck moving up and fishing the middleground or even saving fuel and fishing mashnee flats.

MJ - Have you ever tried fluke fishing off nantucket or Ptown?
