Re: 25 hp Suzuki problem
The red light indicates a "problem," but you already know that. It also indicates that the rev-limiter is activating, and the engine will begin to misfire as you accelerate. If you've had no problems in the past, I wouldn't envision too flat a prop being the answer--unless you've changed boats. The "pee hole" isn't an answer unto itself: it'll show discharge as long as the water pump is working, but if the thermostat is sticking, or there's another source of water flow interruption that you don't notice at W-O-T, that may trigger the rev-limiter. It may be also that you don't notice the "pee stream" stop, because you're being a safe boater; it comes back as you reduce speed, but the engine's still hot, and the rev-limiter still engaged. You could have a simple, or complex problem here, and it may end up being something to involve a dealer with.
