I have a 1989 or possibly a 1988 Suzuki DT200. It has been a great motor for many years and today I had a strange problem. Two problems maybe. I don't know if they are related.
First the starboard side water temp light came on and the alarm was also sounding periodically. The port side was fine. Also the pee- stream was good, looked strong and wasn't putting out hot water. Touching the water jackets and it didn't seem hotter than normal and there wasn't a difference in temp between the port and starboard sides. Sometimes I figure stuff gets stuck and so I ran it up a bit to try and get anything stuck pushed through. This is when I encountered the second problem.
At idle it seemed fine, but once I tried to get up on plane the rev limiter kicked in. I've never experienced the rev limiter but I assume that is what I experienced. It seemed like it was intentionally misfiring, which sounds like the rev limiter. It took me a minute to look at the tach, but the rpm's were way too high. The engine didn't sound like it was that high, but obviously the tach thought there was a problem and so the rev limiter kicked in.
I have never spun a prop so I don't know what that looks like, but that was the first thing I thought of. After I pulled the boat out, I engaged the motor and tried to manually turn the prop, thinking it would spin if I had spun the prop. I couldn't get it spin, so I don't know if that was it or not. Can a spun prop still feel firm?
i am wide open to ideas.
