Re: Engine Repair Recommendations?

Hey, thanks everyone. Just want to get something straight, is this the nut that I'm loosening for the injectors?

That be one of em!

Take your intake breather off for more room...

You can also spray a little WD40 in the intake when cranking to see if she will/wants to start a bit... If so, you're verifying a fuel delivery problem...

Or a low compression problem :-) WD40 which is fish oil is somewhat easier to lightoff then diesel.

I expect he has a loose banjo bolt or somebody stole his fuel. A bad lift pump would do it too, but rare to go out quickly.

A paper towel wiped around the fuel hoses, specially between the lift pump and filter may show a fuel seep. air leak. Not too uncommon.

Oh I see how it is now.... Ring Showoff...

Oh man... re fish oil... reminded me of being a young mechy on the line at a Nissan dealer... tranny's and rear ends were shipped with fish oil in them... Owner was to bring them in @ 1000k for first service to swap out the fluids... many went waaaaaay beyond that... Seriously one of the nastiest smelling things ever...

I'm down with ya on the air leak/seep/lift diaphragm leak....

Re: Engine Repair Recommendations?

Well thanks everyone. Believe it or not I JUST got it fixed today and it's running like a dream. After driving myself insane bleeding the system and trying a bunch of other little things, Marty from Bay Marine came down and figured out it's actually my exhaust elbow. It was just about totally clogged. Had it replaced in 2 hrs. Great dude.

Re: Engine Repair Recommendations?

See! We told you it was a fuel problem, just the the wrong end.

Re: Engine Repair Recommendations?

Yanmars and clogged exhaust elbows.

Will wonders never cease.

Glad you found the culprit.

The reality is that the design inherently causes this issue and has been BTDT all over boating forums. You're now a new "convert' who understands the issue.

Re: Engine Repair Recommendations?

Yup! The bright side is that I really understand a lot more about the engine now and I've now had plenty of fuel system bleeding practice. Not sure if you can see by the pic, but the thing was a total mess. One modification I'm going to make one day, is replace the mixing elbow with a straight nipple/barb. That 45 degree turn catches a lot of crap too.
