I just bought my first boat a few weeks ago, a 14' Landau with a early 90's 2 stroke 9.9 Suzuki.
The compression is the same in both cylinders. The previous owner said the motor runs but that it might need some carb work. When I got it home I put the motor in a trash can of water and got it running without much of a problem. Last weekend I decided to take it out on the local chain of lakes to see if it had any issues.
What I noticed is that at first if it idled for too long it eventually stalled out. Then after about 30 minutes on the lake I noticed that the time span of idling got less and less before it stalled.
After that, I decided to take the boat back to the ramp. As I was cruising around in circles at a low speed (but not idling) waiting my turn to use the ramp the motor started smoking and then cut off. At that point I didn't bother cranking the motor back up and used the trolling motor to get in.
Does anyone know what could cause these issues? Is it the carburetor or something else?
I'm fairly handy, like learning new things and working on projects. Is there a list of troubleshooting things I can go through to properly diagnose the issue myself? Does it take any special tools to work on outboards? Do you think I should try fixing myself or just take it to the boat mechanic? The compression is the same in both cylinders at 40/40. The compression seems low, but I don't know if that is standard for smaller motors. I was able to find the manual for the motor online but it doesn't say what the compression should be.
Any advice would be very much appreciated.
