I'm looking for a manual on my 2006 225 HPDI motor.

My last thread here described a big problem I was having. Ive been back and forth to my dealer and OTHER dealers yet everyone wants to replace this and that every time. I think I have a short in my oil wiring! Enough spending money on pumps and more!!!

Got a guy that is great at this on our forums here in Chattanooga. He wants me to get a full service manual so he wont go into this electrical thing blind.

Can someone link me to the right manual?

***************************************

Here's what I got as for the issue.

* Oil tank on the side of the motor will not fill automatically. I MUST use the switch to the side to fill it. Alarms are working fine.

-Yamaha Tech says wire harness.
-A guy working at Bay Marine in Atlanta says this too. He used to build the motors in Ga, at Yamaha, before the big layoffs.

So why does my dealer want me to purchase new sensor floats in my tanks?!!:(

Re: Manual Help..

I seen those. 90 plus bucks too.

Are the ones posted on iboats usable for ALL electronic wiring? Specifically the oil harness...how it branches off and what all is connected to it.

Re: Manual Help..

what is the issue?
its the same preciosn blend used on all HPDI,3.1L and 2.6L V6 since 1995.
its incredibly simple.

Re: Manual Help..

OK..From the start and everything included.

First problem was that my Fuel Vaporizer Tank was getting way too much oil. Yamaha had us disconnect the line off the oil pump and see what happened. So far during testing, its fixed. I understand this puts just drops into the oil to lubercate my injectors. Dealers says I need a new oil pump...or do I need a check valve? BUT...Maybe this next issues effects it also....

During testing the disconnected pump the other day, I got an oil alarm...I stopped and pulled the hood while still running. My oil tank on the engine was below the bottom line. Another words, it never started filling from the boat tank. I hit the emergency switch and it fills. Yamaha suggested a short in the oil harness...other techs have. My dealer wants to replace the float sensor in the boat side tank. This just dosent seem right to me. I can tell you that all the connections are solid on the harness. Whats the odds I have a short after the harness? Can that effect that oil pump too?

Its been to the top 2 dealers here in town and Im nickeld out!!!!! over 400 in flters for a problem thats only seems to have me replacing this and that each time.

Re: Manual Help..

beware the flying momkeys dressed as techs.
try the next town over.
its a fuel vapor SEPERATOR not a vaporizer.
we dont want vapors.
cant get to much oil as the ecu controls the electric pump that feeds the VST unless the ECU failed.
easy to watch with the laptop to see if its on or off.
no one at yamaha in kennesaw,or anywhere else in the states rebuilds or assembles motors.
you have NOT talked to yamaha.
you may have talked to the consumer help line but there are no trained techs staffing that line.
if you had posted about smoke or blown fuses I could give some validity to a short,but your not so I dont.
when the oil alarm comes on what did the digital tach indicate?
thats VERY important.
when running normal what is the visual indicate?
very important.
by the ability to transfer manual tells me the wiring to the transfer pump is ok,the pump is ok but the condition of the remote oil tank filter is suspect.

there are 3 oil pumps on that engine, an electric that is toggled by the ECU to add oil to the vst at about 1500/1, no typo, 1500/1.
the other is an electric transfer pump in the remote.
the last is the engine driven pump that supplys the intake track with oil.
do a forum search on precision blend and get back to me.
do you have a multimeter and can you use it?

Re: Manual Help..

There is no icons on my tach to tell you a thing about that. I have only 2 lights below my tach . One has an oil can icon the other is for temp.

I do have a multimeter I brought home from work today but haven't a clue what to set it to.

So the small oil pump that sends that small bit of oil to my fuel separator, could not be an issue...instead the ECU?

Lord help me...after a new power head and 6 months down on surgery, all i want to do is enjoy our lake and fishery. :(

Re: Manual Help..

you must have a VZ 225 most likly mounted on a skeeter.
cheapest aftermarket rigging you will find.
do some forum searching, read up on how and why the system works.
dont sweat the VST oil pump, wont make much difference.
its also why I dont understand boat manufactures.
buy the best engine to install and use aftermarket junk rigging.
do some reading, post again and I can walk you though the testing but only if you read some first.

Re: Manual Help..

The best reading I found was the pdf file you linked me too. Its pretty straight up and seems easy enough to follow. Not allot that can really go wrong there.

It did mention that a pinched wire can cause the sensors to not do their jobs....so, i guess I need to make sure the sensors themselves are working correctly on with the multimeter.

Am I correct with this?

Re: Manual Help..

I check the continuity of the switches and they check out fine.

Im having to work in my garage and have no way to put water the the engine to run it. I'm taking the water trap off the bottom of the engine oil tank off and letting it drain until i get an alarm....the pump never kicks in when it hits SW2. If I turn the key switch off and back on, it starts to pump.

Why cant a dealer shoot this right for me? Im very frustrated and upset. Is it a short..is it the ECU...what can I do to fix this thing?! Im out of warranty and cant seem to get what I need.

edit: sensors to switches.

SWITCHES OK!
Got it.;)

Now, not sure if you want me to take a class or what. Ive read and read and read all I know to read. You have something else you want me to edumacate myself with as far as reading mat'l?

Re: Manual Help..

Read this line on your replies to hharbor:

"the ecu controls the ground depending on the switch position in the engine tank. sw1 closed pump off,sw2 closed pump on, if transfer doesnt happen sw3 will close,pump on 2nd command,audivble and visual alarms and rpm reduction."

If all my switches are checking out, could this be a ECU problem...which could also be the problem to my oil pump to the VST. Maybe?

I'm by no means trying to complicate this...its simple 12v on and off stuff. I see and can follow how it works. I guess the thought of all this money I have and could spend has me a bit gun shy.

You help is appreciated....Whats next?:cool:

Re: Manual Help..

my guess is it will work now.
biggest running issues with that oiling system is clogged remote filters.
from engine tank empty when you turn the switch on engine off it should refill the engine tank in less than 180 seconds.
checking this system is a lot easier with the correct rigging.
oil switching for the vst oil feed pump is controled by the ecu but has nothing to do with oil transfer.
that VST pump doesnt run below about 1500 RPM and can be monitored with a laptop or a multimeter.
its fairly common to have to cycle the keyswitch when doing the water trap test,dunno why but I have seen it before.
dunno why but precision blend fails more master tech testees than any of the 5 sections on the test.
and a lot of inland techs dont get to work with the big V6 and V8 motors.
most of what I deal with is v6 with twins.
waited late last night to tie up a 36 regulator with a pair of F350 motors that blew an engine offshore and came in on one.
if you wish I can tell you how to add the third LED that indicates remote tank level.
not as good as having the correct rigging but close.

Re: Manual Help..

I think I'd love to have that indicator for the remote tank! Hell....I'd like to jump a switch to the console for emergency pumping too..:D Just in case it doesn't fill up itself when I'm haulin butt in a tournament 20 miles up river.

Ive asked my dealer, and another one to check my ECU and that oil pump to the VST, they "say" its fine. I'm not so sure! My biggest issue has been WAY too much oil getting into that tank. (so Ive been told) Once they let it drain, drop the motor in the water and slowly gas it till it clears out and idles the motor runs fine...its good for a few days..then it does it again! Filter has been changed recently also.

Sure wish I had a master Tech in our area! The one I have used...charges 150 to hook it up and test it and I've heard from way too many people that they seriously don't do the right job!

If its not to much trouble, I'd like to hook up a indicator for that oil level.

Your expertise here is priceless!
