Looking for a little advice from the boat mechanics on the green screen regarding my outboard motor. The motor is a 2 stroke 1996 Nissan 40HP (NS40C). I have had the boat (17 foot Tracker) and the motor for 3 years or so now. Initially, I had issues with the motor, however, I found that removing the old gas tank and replacing it with a brand new 6 gallon portable eliminated the issues I was having. (would not run at high speed) Last year, I ran the boat all summer (10 or 11 trips) and had no issues. The first trip this year, it ran great until I got back to the dock and put it in reverse and it died. I got it started using the throttle (which is not normal) and got it on the trailer, but the next day, it was really hard starting and did not seem right when it did start. Normally, when cold, it will start right away after choking it.
That said, I went back to square one and did a quick compression test today and I am showing 130 in cylinder 1 and 50 in cylinder. Back in 2018, they both were showing 130.
Any advice on fixing this motor vs buying another used motor?
Any help is greatly appreciated.
