Are there pumps/intakes available for most makes of outboards? I know they make them for Yamaha and Merc. What about OMC, Honda?
I don't think it would be a good idea to try to convert my little 15 horse Honda to a jet. What would the net horsepower be? Probably about 10? It's not enough now, but if I ever found a little bigger outboard, I'd like to know if it was convertible.
