No props. A set of Kamewah water jets. If you want to quibble, the water jets substitute impellers for propellers. In some cases they are harder to access too, but in general they're less troublesome IMHO... just like a big pump... in fact that's what it is. The trade-off is that they're less efficient at low speed because the intake velocity gives the impeller/nozzle a boost just like apparent wind for a sailboat. I don't know from my own experience, but I've heard it said that they don't give as much kick for maneuvering at low speed, but don't have prop walk so that's good. One of the interesting water jets I saw was on a 21' light trailerable sailboat. The water jet came out the back through an extended nozzle about 4" above the water line. Fresh Breezes- Doug King |
