Aluminium prop for small long tail

Postby duckland » Fri Sep 13, 2013 3:36 pm

I'm in the process of ordering all parts needed to build my first small 7hp long tail. I would like to hear what you think about SPS propellers for a small long tail. Is it better to pay 150 $ for a stainless prop or buying few spair SPS aluminium props at 15 $ each that will serve also as a shear pin for the drive shaft ?

I've never driven a Mud motor before. I have no idea how long an aluminium prop can last in the mud.

Keep in mind that you will have to machine a taper and a keyway for the SPS prop. With the stainless mud props you just need a 3/4-10 threaded shaft....

My hunting buddy has a machine shop. He'll do the tapering job for me. Witch size would you recommand for a 6.5 hp ? 6.25 x 5 in or 6.5 x 5 in ?

I'd get the 6.5 or 7.
