Thumper, is that a 16 foot grumman canoe? I have an 18 ft Formula Vee with a 115 Yamaha jet and wish I had a 150 (Prop HP of course).

XSTLHEADER, I don't know what kind of river that you will be running, but suspect if it is not like the waters we run here in the northwest, that you may be better of with a "macs" propguard. I have these on both of my kickers and they have saved the day many times.
Like they were saying, you lose ALOT of power when converting to a jet pump. I often reinstall the lower prop unit on my sled and it will hit about 53 mph top speed (Best conditions) but with the pump, I am lucky to hit 35 mph. It takes much longer to get on a plane also, and I have a stainless impeller to boot.

Dad, think that if I practice hard, they'll let me participate in the SRC ?
