Boat was running beautifully (30K @ 4000 RPM) until I moved throttle to neutral for a few seconds, raised and lowered the prop and then throttled slowly forward. The prop did engage and the boat move, but very slowly even though I gradually increased the RPMs to the max. The same was true in reverse. I checked, removed and re-installed the prop pins so I know they are okay. When I ran the boat out of the water, the prop does speed up when the trottle is advanced, it just doesn't seem to do it when it is in the water under a load. Any ideas? Is the problem somewhere between the I and the O? Are parts available for old Johnson I/Os? Remember, the boat was running perfectly fine before all this happened and still cruises at a nomenal speed even when the RPMs are showing the boat shoulod be running much faster.
