Hi Again
If the orginal prop is 1.34 " dia then Its just slightly bigger than 34mm not 32mm. What i'm getting at with talk about the prop being efficent is it will go faster with less power . The orginal plastic prop being rather flexible,it will waste some of your power when it distorts. A X430 will likely be too small for many uses in this big of a boat. The X432 metal prop works for almost everything. If I had the out drive on my bench I would make a different short shaft that would have 4mm threads to make use of the Graupner line of K series CF props. They work great and are about $6 ea and come in a great many sizes. From 29mm up to 45mm. I do a lot of custom driveline work and specialize in motor couplers. The advice to cool the motor is right on and should be done when possible. Always oil the prop shaft and motor bushings. I have seen too many prop shafts seize up because of running dry. A great many racers that I know lube em up before every run. n.h.schmidt
I think I am going to go with the 432 but of course it is out of stock at offshoreelectrics. Anywhere else I might be able to pick one up? I think after adding the cooling and prop I am going to call this boat complete. It is plenty of fun just the way it is. It's fast enough, jumps out of the water, handles well, and just plain looks cool. My next boat will start with an empty hull so I am not paying for things that I will be replacing right away. Maybe a 12th scale hydro since proboat is dragging there feet with the Elam. Thanks everyone for the info!
