MerCruiser 5.0 (305) / 5.7 (350) V8 gas parts: good
Factory standard engine — you entered “MerCruiser gas V8 inboard (1985 on)”
GM small-block Chevrolet base engines, so internal parts are everywhere. Marine exhaust manifolds and risers for 1983–2002 small blocks are sold by many aftermarket makers (Sierra, Barr, Osco and others) through Power Boat Supply, Hardin Marine, Basic Power Industries and similar stores; Mercury sells genuine parts through dealers.

Common problems (2)
-
Manifold/riser failure and water in cylinders exhaust
Cast-iron manifolds and risers rust internally or their gaskets fail, letting water back into the cylinders; small amounts cause hard starting and rough running, large amounts hydrolock and wreck the engine. Service roughly every 7 years in fresh water and about 5 in salt.powerandmotoryacht.com · forums.iboats.com · justanswer.com
-
Overheating from scaled manifolds cooling
Rust and scale inside the manifolds restrict cooling flow and cause overheating under load.powerandmotoryacht.com
