A few months back we bought a 2003 20i Tige ski boat.
Took it for a test run before buying and it ran great for the 30 minute test run.
In the months since buying it I’ve had some upholstery work done, I put on FAE stainless mufflers, and I fixed a few other cosmetic items.
Last Saturday everything was finally back together, so Sunday it was lake day! Boat started up great, idled out of the “no wake zone” great, and I hit the throttle to get going fast. Fifteen seconds later the motor throttled down by itself and started “coughing”. I pull the throttle back and the engine coughs then dies. I check around under the engine cover and everything seems fine. Start it back up and it’s idling great. At this point my daughter is on the tube floating behind the boat and wants to get pulled around. I pull her in idle foe about a minute and everything looks/seems/sounds great, so I throttle up. It’s running perfect for about 10-15 seconds then it chokes and throttles down by itself, and ultimately dies.
This happened over and over, so we yanked the tube and just went for about an hour idling cruise, ate lunch and headed home.
I’ve worked on engines quite a bit when I was younger, and the only things that came to mind was bad gas, in-line fuel filter, or fuel/water separator. So yesterday I changed filter, separator, and I put an addictive in the fuel. Hooked up to water in the yard this morning to test out. Idle was fine, but at 2500 rpms it lasted 15-20 seconds. Next I took the air filter off. Now I got 2500 rpms for a full minute! Thinking I need to get a new air filter, I was just about to throttle down and shut off. Well, the motor beat me to the throttle down, same issue.
All local boat mechanics are 3-4 weeks out, and I have a house boating trip planned in 2-1/2 weeks!
What is the next thing that I check?
Your help would be very much appreciated
