Hey guys, i bought a 2006 Bayliner with 5.0 Mercruiser engine, its carborated..has alpha drive.
my issue is as follows:
-When driving the boat slow under 8knots it is fine and no issues, but then when getting on it, it just wont' plane, the engine sounds strange and constricted, and rpms don't go all way up so its not slipping..then it gets hot and i have to back off or shut off for a minute and it instantly cools back down under 175..i realize my risers/ manifolds are original and need to get done, but it doesn't seem like thats the power issue, as i stay on it, boat won't plane, sometimes does but still struggles, trim tabs work (indicator doesn't work)
i've had the the carb rebuilt i've had a tune up and that didn't help..what gives?? we checked for spun prop and mechanic said thats not the issue..outdrive shouldn't be the issue as RPMS' don't go all way up so its not like its slipping..i don't get it and mechanic can't confirm. I do have a big swim step with 2 chairs on it and a grill but that shouldn't be it..
