well here it goes, first off i am a mechanicaly inclined person but am far from a marine mechanic so go easy on me if i do not use the proper terms for parts. recently i have been considering fixing up a boat I own that has not been run for about 3 years. This is after my bass boat died last week. The boat in question is a 1976(pretty sure anaway) Starcraft 20 ft aluminum, bow rider style with a mercruizer inboard/outboard drive system. it has a chevy 4 cylinder(cast iron block-iron duke to dirt track auto racers) i am fairly sure it is a 2.5 140hp. the engine runs great! it has less than 300 hours on it and the hull is in good shape also. the last summer i had it on the water the coupler that bolts to the flywheel connecting the engine to the splined shaft on the mercruizer drive melted where the rubber is inside the coupler. i replaced the coupler myself. while working on it i noticed that the bolts that mount the wooden engine mounts to the hull of the boat were loose. i figured this is why the rubber burnt out of the coupler because the block wasnt bolted down solid. so i tightened the bolts. i talked to a local marine mechanic who turned out to be a crook, about the problem. he told me to put the coupler in and bring it to his shop so he could line the drive system up with the engine. i thought this made sence. 3 weeks went by with no work done by the mechanic. i showed up to see what was going on with the boat. Even though the trailer never moved from where i left it with grass growing up around the tire, the guy told me he lined it up and charged me $20. next day i was on the lake and the coupler again burnt out.
my questions- is there even a tool to line up the engine and drive system?
what causes a coupler to burn up?
would the loose wooden mounting blocks cause this?
thanks for any help-adam
