I have a 1985 Johnson 55HP (commercial rated) motor. When I got it I found out it didn't have a starter. It had the right flywheel so that was not too big of a job to add. I had that installed on it and it cranks right up. But, and this is a big one, it doesn't have a charging system. How difficult will it be to add that? It would be nice not to have to charge the batteries every time I take it out. If it is possible< is it something I can do? Also, the water pump is working on this motor. It was set up for I don't know how long before I found it on a pallet in a man's warehouse in Houston. When I got it running it pumps water out the pee hole but after having it in the water a few times I have noticed that when I idle it for a couple minutes like when we are checking jugs the water it pumps out starts steaming. I immediately rev it up a little and it will start cooling down. Does this indicate I should change the water pump out? Also the other motors I have had in the past would push water out the little vents along the top and back of the shaft. This one only put the water out the little pee hope. Why? I am just trying to understand the quirks of the motor better. Thanks for any help.
