Re: Motoring RPM
Had this boat with this engine. Before blowing the bucks please check the throttle cable. Unscrew the four screws at the corners and lift the access panel in the cockpit sole out. Detach the linkage to the engine. Have someone push it stop to stop and make sure there’s full range of movement. With cable off move governor on the engine and make sure it has full range of movement. Then reattach cable and check for full range of movement. There’s stops on these things. They maybe set wrong. The cable maybe binding or kinked.
You report no smoke, easy starting and normal running. So would check the simple stuff first.
Loved this boat. Never liked the weird way you get full engine access.
BTW had the 3 bladed maxprop on this boat. Dramatically improved low speed handling. Especially backing up.
