Hi everyone. I want to put a MaxProp feathering prop on my H34, I'd like to know if any H34 owner did it and if so did you go for the 2 or 3 blades model and also what diameter and pitch did you use. Thank's Yves Langlois S/V Opium

Suggest Ask Max-Prop
The prop listed under "The Boats", and in "Boat Models and Specs" for the H-34 is a 15 x 15 inch and the shaft is 1-inch diameter x 50.75-inches long. I believe the OEM shaft was bronze. The three-blade is significantly more expensive than the two-blade but should have less vibration. This can be discussed with PYI (link below). They're good people to work with. I went with the two-blade on our H-35 over 12 years ago and it's worked just fine for me. To further reduce vibration suggest changing out the bronze shaft with a stainless one and ensure that it is "true". The pitch is adjustable in increments on the Max-prop and the instructions will say what the pitch is for a paticular setting. I pitched mine up one notch and the black soot on the stern essentially went away. Simple to use; after the sails have been hoisted and trimed just turn the engine off and shift into reverse - the prop will automatically feather. Great addition to the boat and no sail changes are needed! Oh, and don't let your zincs wear out.

MAX PROP is great
I installed a 15" 3 blade on my 33.5.The preformance is incredable. Backing up is a pleasure. I do not remember the pitch but i changed their recommendation by 2" and i missed top r.p.m. by 400. I need to drop two more inches of when i haul out.Send me your e-mail address and i will let you know the correct pitch. My address is bullpin29@mediaone.net
