Thanks to the 1st time homeowner tax credit I will have have some money this spring to get a newer 4 stroke for my 15' Gregor. Right now its got an older 30hp with a prop, but I'm really leaning towards going with a jet. Looking at the Yamaha 40/30 in a jet, or the Honda 30 if I were to stick with a prop. Not sure how well the jet would perform on this hull (its an MX model w/ side console), but I know I will have to remove the last 3 feet of the keel to make it work with a jet. Another issue with these boats is although they are welded, the metal is pretty thin compared to most river sleds, so wouldn't want to take it anywhere too extreme. The boat would be used about 50% of the time in lakes and salt (maybe a trip to Seiku, E. Vancouver Is.), but I'm wanting to be able to use it on rivers and tidewater areas the other 50% where I would not feel comfortable with a prop. Just curious if anyone has made this switch. Do any of you jet guys run out in the salt too? I know the ideal situation would be to have 2 different boats, but I can only afford to make it work with 1. Any input or suggestions are appreciated.
