Headed back in today and couldn’t get above 4K rpm...
Here we go again!

Starting with fuel filters this weekend then ordering VST, gaskets, msc., and May send the injectors out locally...

No long trips in my future for a while... grrrrrrr

Ray, same symptoms I had last year. Among other things it was the high pressure fuel pump. Sorry. $400+

This is why I hire out all my outboard work.... Season is too short. I am sure I could save a few bucks winterizing and commissioning engine, but he knows and can recognize stuff that I would be guessing at.

Up and running!
Changed out bulb, micron filter, plugs and OEM filter..
Emptied out most of the fuel out of the 10 micron mini filter, shook it, dumped into glass , got this...
65338
Not sure what that orange stuff is, feels a little gritty

The black stuff is definitely rubber IMO

Got her up to 5K RPM good enough for now...
Ordering VST filter to change when I have time..

Ross, totally agree. That's what I did before I sold the boat.

Is the orange stuff varnish?
I know my brother ended up replacing his tank and all the lines to end his fuel problem.

Hmmmm, I dun know but the aluminum tank is 14 yrs old, I worked on it last winter because it had come loose. I knew I should have replaced it then but .... :smash:

It’s the rubbish in fuel these days it turns to a jelly. As a full time mechanic it’s only getting worse. This year I’ve had more problems with equipment that sits over the winter then I have in the past 8 years. I replaced all the fuel lines in my boat last year and for the short change it cost prob do it again. The lines will degrade and break down push particles through everything. Makes me appreciate the short line I have from my little 6 gal tank

That's true Ray but I am not a good mechanic.

LOL
couldn’t remember, was it last year? Or year before!
Pretty sure I got a bad fill up of chit gas and it went right through the engine, had the injectors cleaned also and now back up to over 5K rpm....
Now I’m down to a fuel line leak that dumb arz me didn’t catch before putting it all back together...:smash:

Nice to see progress towards actually fixing a motor problem, I never got past the gremlin I was chasing in mine last summer :)

Unrelated to your RPMs, does that steering knob squeak like the #^&#^&#^&#^&ens for you? I think I’ve got the same one and have been trying to think of the right lubricant to get the damn thing to shut up!

spend 10k on stuff you don't need and the wife will drown out the loudest noise you can think of.... just a thought.
