Boat was driving fine today. Came back a few hours later and started it up and smoke was coming from the exhaust and it was sputtering a bit.

I talked to a neighbor and he seems to think that I need to clean my water filter or my pump is overheating or failing. I have a 98 moomba outback. Has anyone had any experience with this or can help me out with any advise to start with

Thanks guys!
