Hello, looking for a few ideas of things to check on my 06 Crownie with a 4.3 TKS Merc Alpha I/O.
Boat was idling like crap, stalling out etc. My trusted mechanic recommended rebuilding carb. Boat now runs like a dream on muffs. Run PRETTY MUCH like a dream on the water, but has picked up some minor surging since the carb rebuild. Between ~1.5k - 3k it has a 200 RPM surge. WOT runs beautifully. Also desiels a little bit after some hard running. Mechanic is in a tough position because the issue only happens when the boat is under actual load.
My next idea was to try to re-do the idle mixture and curb idle settings when the boat is on the water and hot. Does that sound reasonable? Any other thoughts on what I can check? This didn't happen before the rebuild. Also new fuel filter, cleaned up the distrib rotor, clean gas.
Boat is so close to being "perfect" after running like crap for a couple years! Appreciate any pointers!
