My father recently gave me a 1990 Cajun with a 1991 Johnson 90Hp V4 on the back. I need some advice on repair or cutting my losses. I'm a fairly advanced shade tree mechanic so large\complex repair I can most things but I'm also not wanting to dump a ton of time\money.
Some BackGround.
1. Boat had been sitting for 2+ years.
2. My father said the boat has always been hard to start & idol since he has had it for around 6 years.
3. Once it was running said it always ran great once warmed up.
Current
1. It hates to idol and will really only crank with extra throttle applied
2. Took it on the lake and after bogging\turning very low RPMS around the lake for 30 minutes it would slowing ramp up and run really good and fast. If I slowed down it would take another 2-3 minutes to get up to a decent speed again.
4. Took it home and changed spark plugs and had nice solid looking spark on each wire.
5. Drained all the gas and sprayed 2 cycle carb cleaner in the carbs
6. Took it back on the lake and it would never plain back out and gain speed.
7. Ran a compression test today and everything is between 60-72 pounds :-(.
Just needing options if I should cut my losses or maybe try new head gaskets and carb rebuild kit. I got about 1k invested at this point between the batteries\title\and floor repair.
Thanks
