Adjustable props.

[hillrunnerfl]

I am building rigging out of stainless and will be putting my O-470 GPU on an early light weight 15 foot Rivermaster hull. (two guys can pick the hull up and walk around with it).
Running my 470 with my wooden paddle prop on the same Rivermaster, it ran a true 52 miles per hour in deep water.

I am looking to purchase an adjustable composite Sensenich prop.

Now my question???

Two or three blade? I have seen the three blade on several boats, but don't know if the 470's were stock or had dome pistons. (people lie).

My 470 will turn my wood 70-34 Sensenich paddle about 3000 RPM's

Anyone have experience with the three (narrow) blade versus two blade Sensenich prop??

I think if you do some checking that the Power Shift prop will be a better choice.I see more of them and hear nothing but good on the preformance
of the power shift props,Waterthunder seem's to have done some in depth testing on props and you should read what he had to say.

I'll be running a 3 blade Sensenich on my new 0540.

I run a car motor with a box and a 6 blade warp drive and talked to several people and they said that putting a 3 blade sensenich on on there boat was like putting another gear box on it. would like to try it .
