Hi
I am looking to re power I have a small go fast boat that weights about 250 pounds.
I have a stock 1977 55 Johnson on it but I am having water pump problem lower
unit will not separate. My cmc power trim unit is set up for short shaft motors
would like to find a good short shaft 1980's 55 hp . They are hard to find I am
currently looking at a Johnson 1987 stock 40 hp short shaft but can you do much to modify that ? I was going about 46 mph with what I had all stock would like to go a bit faster .

Thanks any help on this would be appreciated
