H31 Prop....Left or Right?

[Bob Rutland]

I am about to order a new prop for my 84 H31. Do I need a left or right hand prop?

 

[Mark M Smith]

Right

My 31 is rt turn

Probably right hand if Yanmar Engine

My 28.5 had a Yanmar 2GMF, my 34 has a Yanmar 3GMF. Same vintage boats as yours. A friend's 31 in Mississippi has a 2GMF. All these are 1 inch tapered shaft with right hand rotation. Check on your current prop. You'll probably see something like 15 X 15 RH (this is an example only) where you get the diameter and the pitch as well as the rotation. good luck
