Looking for some straight forward thoughts on this. Picked up a 21' open bow jet at the end of the season last year. Super clean 20 year old boat, I'm fine with the issues it has, it's used. Started my process of going through every detail of the boat a couple of weeks ago to get ready for the season. I'm a pretty decent garage mechanic, came out of high school in the early 80's and went to work as a mechanic in training at a couple of old school service stations. Grew to hate it as a job after about 5 years. Enjoy it when it's my stuff. Previous owner told me engine was rebuilt by a old guy they know who used to build engines not to long ago, hoped he was one of the good ones, not so. Compression check all over the place. Attached in pics. This boat I won't run hard ever, it's to hang out and enjoy the water. I have a different go fast boat for that.
My thoughts are I can get through this coming season with the rings not being so great, #6 the worst. I'm thinking I'll oil all of the cylinders (Marvel Mystery) and run a compression check again to confirm. My real concern is the evidence of water in cylinder #7. I could pull the plug after every trip to see if it's getting worse. Water is the unforgiving part, too much and boom. If I'm gonna rebuild it I'm gonna have to do it right and I would prefer not to spend the money right now. Previous owner told me there's a oil leak, either the oil drain hose, I hope, or because they set the engine to low I hope the pan didn't rub the intake. Drive line was binding, I could feel the vibration at idle when I ran it a couple times. Angles are off. I'll correct this too. This CV-19 shit hasn't affected my business that much, but this is one of those unnecessary expenses I would prefer to postpone.
