Sad to say I hadn't had my boat out in the last two years, but I finally managed to get her back in the water this past weekend. I expected some issues as in this time I had to replaced the exhaust gasket as it was leaking and I also installed a new water pump this past week. Since the last time I ran her I replaced all the 3/8" fuel line under the hood and I installed a new primer bulb as the last one didn't seem to get hard when primed and age was unknown. I honestly can't recall if, or how much seafoam was added prior to her setting, but the fuel filter didn't look bad. I usually add seafoam throughout the running season to keep things clean inside and aid in storage over winter. I've never had an issue to date.
That said, prior to running at the lake, I did do a quick decarb, basically 10min of running 3/4 gallon of gas with oil and 8 ounces of seafoam. I didn't do more because my top end is normally pretty clean, though I'll admit the plugs had been a bit dark from running rich due to the exhaust gasket leak last time out. I dumped rest of mixture into tank and topped off with fresh gas. Dual 12 gallon tanks and I added 8 ounces of seafoam to the 2nd tank.
When I got to the lake, she was tough to start in the water, but I finally got her going and let her fast idle for a good 15-30min. Just when I was getting ready to go, I heard a buzzer.....not 100% sure if from my boat or another at the ramp, but I shut her down quickly. I rechecked oil prime, engine felt cool and she had been getting oil judging from the smoke. After re-check I fired her back up and never heard that again....it came from under console. Is that where the buzzers are? I've never had one before?
In any case, low range and mid range where the trouble areas, she seemed to run smooth at 3k RPMS and up. She wouldn't start on normal idle, I had to push lever to fast idle, then quickly move to gear to get going. She did get easier and easier to start as the day progressed and I would shut her off once in a while to see about progress, but never at normal idle.
My thought is I'm sure there is some gunk in the carbs from sitting, but with this is a carb rebuild going to be in future or should I be able to get her cleaned out? I do recall at beginning of seasons she's been a bit finicky with the 8ounce seafoam in the tank, but never like this. I've wondered about any other additive to run in tank to aid in cleaning out any gummed up gas that might be floating around? Is carb cleaner a bad idea to add to tank?
With all of that said, I'm also planning on replacing the fuel line from powerhead to tank(s) to eliminate any possible issues there. I'll clean and possibly replace the plugs and look into cylinders to see if any carbon. I don't think this is a prop issue as I've never had issues with it and that shouldn't affect starting, but thought crossed mind. I also have a new fuel/water separator that I plan to install as that's been a few years as well. *FWIW, last year I pulled the gas from the tanks and ran it in my truck before it got old and I pulled 12 gallons out of each, so minus any possible residue the tanks should have been dry to start with and I added just over 12 gallons at the pump to the 2nd tank and from what I had poured in at home, which was also fresh, I came to about that again on 1st tank, so very confident they were siphoned dry while it sat the last year +, when I realized it'd be this year before I got her going again.
Any suggestions? I think I ran most of the 1st tank which had the remainder of decarb mix in it out and I think I ran most of the 2nd tank out as well, but haven't opened to look. The tanks are hard to see level in. I don't think I've damaged anything, but don't want to either. Do I change the hose and the water separator and try again or am I looking at carb work? If so, I've heard those sonic cleaners do wonders and if I don't have to tear down 6 carbs that'd be awesome. I've done that before and since I don't want to attempt to sync 6 carbs it'd have to go to a shop to have that done.
