Duromax motors are cheap and been hearing good things and competition aircraft for prop and hub.

 

them things are homemade. There aint no real universal fan design that fits any and every boat.

 

I thought there might be someone that sold some sort of fan motor package.

 

I have seen something before like that but I cant find it. where do i need to look for information regarding a build plan?

 

Bout as close to a kit as your gonna get, but its not your typical troller fan.

I started collecting parts, and eventually came up with this. 2" aluminum pipe for the pedestal. 2 3/8" flange bearings. Or one flange, and one press fit for the bottom. 3" aluminum pipe slides neatly on the 2". I made steering drums by welding plate to the 3" pipe. Also for the motor mount. A sawz-all cuts aluminum neatly. I bought a tubing roller from harbor freight, and welded the shoud. 6" aluminum pipe for the bearing shells. Stainless cable for steering. Garage door pulleys, and fab your steering drums of choice. I used a go cart sprocket, and a small gearmotor for steering. Arrow prop makes a lightwieght prop. I recommend a two cyl engine over a single. The single will thump. and unseat the carb float. I did go to propane, and it solved two problems. The carb problem, and shutting the motor off. I can still run the motor on gasoline. At least until the plugs foul. Nothing is as easy and it looks, and If I did not have the local scrap yard, and a small lathe. None of it would have happened.
