Yes. The combo of exhaust
gas & saltwater is very corrosive and can cause clogging and even a rupture of the mixing elbow
over time. If the exhaust
is restricted then that would also restrict the amount of air getting into the engine
Also, if you are new owners it could mean the boat was sitting for awhile before it was sold. If so, it could also be the injectors. When they sit they can foul over time, and that usually means too rich a mixture.
Then again, I'd also be inclined to try DeepFrz's suggestion of running the engine
w/o the air filter. As he pointed out, it's one thing that's changed. Besides, it's easy! Fwiw, my Westerbeke's don't use air filters, although apparently other marine
engines do. Something to check out . . . .
Anyone care to raise Tellie's wager, or should we just call?
