Maybe this should be in the trailer towing section but a good example of what happens without enough tongue weight.

Just looked close at th4 capacity plate again. It reads that it is a replacement for the original with owner supplied information. So I guess that we are looking for pre 1972.
I just had to replace the alternator in one of my trucks after 175 thousand miles and this was packed with the replacement. I have no idea if your engine has an ECM but in my case the brown wire feeds the PCM and activates the warning light. The gray wire excites the field coils and duty...
Not saying this is your case but alternators can be damaged if the battery is disconnected while the engine is running. I would check the battery connections, cables, battery switch and the engine ground cable.
At 4800 feet you would be putting out about 17 horsepower. That would give you a speed of around 24mph at sea level. Your speed doesn't sound that far off what would be expected. Get one of those 15 dollar induction tachs and once you get your speed/rpms you may find you could get a small...
Depending on the size of the motor two people can slide it over enough depending on the width of your transom at the splash well. There is usually enough slack wiring and fuel line nothing needs to be disconnected. Connecting up the motor first and the helm second is usually better but not...
The picture shows only 2 bolts being used, I take it you were using three. That puller looks pretty sturdy. As raceone said tighten all three bolts evenly and then rap the end of the puller. There is plenty of pull on the flywheel from the energy it took to stretch them when they are torqued...
Boat speed vs power is not a a linear relationship. If so by increasing your power by 55% would result in a speed of about 58 mph. The truth is calculating speed vs power for a planing hull is very complicated depending on a lot of factors. Even the wind resistance force is quadratic meaning...
I run an almost identical boat (Crestliner 14) with a Tohatsu 30 hp witch is a little more power and a 9.9 inch by 13 pitch prop for a top end of about 30 mph. With my old prop witch was a 12p it would over rev by 150 rpm with only my self on board. Just a guess but if your motor is working ok...
