I just picked up my first river runner. It is a 1995 G3 with a 1996 Yamaha 25HP outboard. First let me say that this boat came with a tank of gas that was about full so I have no idea how old it is. My engine idles great at half choke but the second I take the choke off it starts running at an extremily high speed. It revs up so high that my wife took off running because she thought it was going to blow up. In reality it was probably only revving to maybe 3500 RPM or so but it scared her none the less and it surprised me too. I let the engine run for about 10 minutes on muffs in my back yard before I ever took the engine off of choke. So please help me understand why my engine revs up so high when I take it off of half choke???
