I have a 95 Evinrude 90HP 2-stroke. I have lost my top end power. When I push the throttle to max power it jumps to 3800 rpm then falls to 34-3500 rpm. It used to run at 4500 rpm at full throttle. I can't even come close to getting up on plane now.
I have replaced all the sparks plugs...
I had my jet boat on the river last night and I lost my top end power. It happened when I slowed down for a shallow area and when I tried to power up again I had no power to get back up on plane. It idles fine and I have about 1/2 the power it normally does.
-I checked for rocks in the jet...
