I bought a 4 cylinder (1984 ish) Mariner 75hp outboard in the winter. It's just come back from a service with my local Marine Mechanic and I've been told to "get rid of it"
Basically it starts OK and if you can get it WOT it flies. Problem is as you open the thottle it can die. It's really difficult to re-start when this happens. Youv'e got to open the thottle at just the right rate, it's impossible to cruise at slow speed. I'm told the crank and seals are worn and it's not worth repairing. I've no real reason to disbelieve the mechanic, he should know better than me but if he's wrong I may be scrapping a perfectly OK engine that needs a $100 fix. I suppose I just don't want to believe him! Anyone seen this engine problem before? He says it's common on these engines.
