XB2003 Set-up

bnajackson5 · Mar 9, 2009

I am finishing the rebuild on a Mariner Promax 225 20". It has a 25 pitch 4 blade offshore prop. 12" setback. Speed is great but it is most important to me that boat handle well.
What height would you set motor for best handling?

Need more info on the 25 offshore prop. At 12" I would say a 1/2" below pad would be a good place to start.

It's a 25 pitch four blade. It has vent holes completely around the base of the prop. I don't know if it makes a difference but the mid has had four holes drilled for exhuast relief.

I have the same boat and motor. I am running a 14" set back 3/8 bellow with a 28 Hydromotive Quad IV. It is the best prop hands down for carrying weight and still running into the 90s with a 225 2003 combo. http://www.hydromotive.com/int_quad4_OT.html
