Depends on the engine, transmission gearing, etc... more information would be useful. I'd highly recommend you read the POST in my signature to help you get the most out of your time here. It has tips on searching sailnet, writing a good post, etc.. Welcome to the asylum.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I recently bought a new prop through West by North.

I'd highly suggest picking up the phone and calling them. You might want to find the transmission gearing as SD suggested (google is your friend). WBN will take care of you from there.

You must state the motor and the gearbox reduction and the direction of rotation of the prop, and the shaft size and the shaft taper.

If you don't know the gearbox reduction, mark the flywheel and the final drive shaft and turn the flywheel until the final drive turns exactly once. Count the rumber of flywheel turns it needs to do it.

The Volvo MD17C turns the final drive shaft once for every 1.92 turns of the flywheel (the crankshaft, effectively).
