Any tips or tricks?

Repair shop says exhaust valves in cylinders 2 and 6 are tuliped. They recommend to replace the entire motor due to age and "unknowns".

Boat has less than 500 hours, I'm the 3rd owner...bought in May 2020.

Boat ran great when bought. Quit on first trip and found rotor cracked. Replaced cap and rotor and it ran like crap. Took it to the repair shop and that's where I'm at now. They've checked everything, found it "way out of time". Not sure how it went from running great to "way out of time".

Machine shop said there SHOULDN'T be any lower engine damage, as the tuliped valves was most likely due to timing issue. They said I'll probably be good with getting both heads done ($400), shop says to replace motor (they haven't gotten me a price yet).
 
Get a Chevy crate motor and change the freeze out plugs, start fresh but affordable
