My Etec has packed it in

90 opti is only $12000 fitted.

first thing you need to do is detimine what caused the failure.

i have had a few insurance claims approved for contaminated fuel before.
if it still leads back to mechanical failure i then i would be contacting brp via phone and request if you can purchase a powerhead at cost or if they have a demo engine you can purchase.

Really sorry to hear about your issue.

This has me confused: could some one 'please explain' how contaminated fuel could cause a big end failure in a direct injection engine?

I am sure if you provide BRP an indication of the findings they may provide a list of potential causes other than fuel quality. One would suggest the oil system needs a thorough going over by an independent mechanic, you can be sure your dealer won't put his hand up if it's something he did wrong.

Bazza contamination of the oil be it with air or water is where I was headed. Lots of toluline, paint thinner, acetone in fuel can kill the pulse lift pump diaphram and wash oil from the crankcase at a longshot. Also cause detonation / knock and extra load on big end. Big ends are so oversize to start with in that motor and rarely ( if ever) fail so unless there is a oil pump/ injector failure, with alarm failure etc etc it might just be a bearing collapse from badly manufactured bearing or one that for some reason had a oil pipe kinked at some point in the motors life.
A badly dribbling injector may at a long shot or computer EMM injecting late and sparking too early?
Too much fuel causing carbon , then hard carbon and bore scoring then overload big end?
Water in fuel, injector siezes. No combustion means no gasflow so reeds don't open much so little oil / air mix vaporises and bearing after many hours gives up due to extra loads an dbore scuffing due to lack of oil.


BRP know the big end is overbuilt and unless it was a manufacturing fault, no oil or water in there they should last forever so are doing the blanket - "not our problem" . Sort of sucks especially if over serviced by them and if on further ivestigation a cause can be found like the EMM is stuffed. Colour of bearings , type of piston scoring , impeller condition and so on should tell a good mechanic a little about what has happened and should be able to find the cause.
Stuffed airflow sensor - emm puts in wrong mix.
This could be a simple stuffed impeller ( badly fitted, cracked housing, no key in it) with a dodgy engine temp alarm , wire not attached and the big end just happened to be the last thing that broke before it stopped .
Barometer in EMM amy be stuffed giving wrong fuel oil map.
Replaced injector without EMM coefficients being updated
Dodgy fue - 20 % ethanol fuel - EMM runs it lean and as boat is heavy for a extended journey piston expands or just gets too hot scores and overloads big end eventually kaboom- failure.
Head gasket failure, water washes oil off bore , scores, binds
Sucks the screw that holds the butterfly on in the plenum - jambs in main or scores bore. Reed sucked in.

I'm with you I would have had the dealer check warranty history of the motor,check all the service work just done, pull it down with a independent engineer beside him and discover exactly what went on and why starting at the beginning proving all alarms were working, downloading the EMM report , checking external fuel , filters, all startic injector and drop tests etc etc and then oil system check, oil quality then start the wrench work stripping it.

A quick look at thngs can rule out 90 % of possible causes by someone who wants to know the right answer.

The thing about all the directed injected motors is the computers on them are really smart and compensate when power is lost in one cylinder by adjusting the timing and injecting more fuel to try and make the same power output at the % throttle position from the other cylinders. They are so smooth and balanced and adjust the idle automatically Etec don't have a exhaust temp or burn sensor / oxygen sensor so the computer assumes all is OK if it makes teh revs and doesn't overheat. It just asumes a extra 10 fat blokes got on board with eskies or you are running it just off the plane . Even other brands only have one combined exhaust sensor so one cylinder can still have a problem and if within in the parameters in the Computers map no alarm sounds. In a perfect world you want to know the correct oil , fuel and air mix actually made it into each cylinder and combusted to produce exact power not a average combined guestimate from all cylinders and a assumption that a single temp sender will tell the whole story quick enough to stop a implosion. .

A shot big end would have been banging its head off well before any rollers or large enough metal escaped to stop the engine.
Did you hear any noise, like BANG BANG BANG BANG?

another thread with second hand motor purchase http://www.ausfish.com.au/vforum/sho...w-boat-project

Keith Falkenhagen from Jeffers MotorSport Marine at Burpengary is a Suzuki dealer and originally sold this motor to one of his clients who wanted to upgrade to the new DF140a with lean burn. I paid $8500 fitted and serviced. It's an '07 model with 560 hrs in very good nick and had been regularly serviced by Keith since new. I was very impressed with Keith and his team. I suspect there will be more on the market soon as others will no doubt want to upgrade also.

I think cormorant is on right track i would be talking to BRP i have two 130s done in access of 600hrs done a starter on one at just under 600hrs spoke to BRP though my local dealer and they replaced it under warranty worth a try.

Why is it so?

[ozscott]

I thought anti corrosion coating had got a little better than that.

That's some serious pitting in the piston.

Cheers

[Chimo]

But why? Is it lack of oil or what?

Sorry guys just put the pics up between customers at work.
I went and picked up the boat yesterday afternoon and the mechanic told me it is nothing to do with lack of oil or water it was just a bad piston. From what he tells me the small bearing up inside the piston would of went a long time before the one at the end if it was from lack of oil and also the marks around the outside of the piston would have been a lot more extreme. I am going back early next week to pick up the rest of the engine and to get the emm report which will show any fault codes.

[Spaniard_King]

Looks to me like the piston ring locating pin has come adfift and floated around inside the combustion chaimber, seen this before in the mid 90's V6's

The sandwhich plate looks consistent with salt build up not corosion

Have you had it since new RC?
I'm surprised you never heard anything I was standing about 20' away from one at the ramp & couldn't even hear it running so you'd think you could hear that kind of damage going on.
It got me thinking of retro fitting an etec muffler on my old bomb.
Broken bearing cage letting the rollers out? You'd think they would just fall to the bottom, there must be a hell of a cyclone going on in there to push them up to the combustion chamber.
Terrible thing for a relatively new motor.
