Pearson 323 repower - what prop?

I'm in the process of repowering my 323 with a Universal M3-20B (20HP) and wondering if I'll need to change the prop since the new engine max RPM is 3600 as apposed to the old at 2800. Does anyone have a recommendation?

Trans ratio 2.13 - 1

I don't know, but I think those that would know, would want to know what transmission and ratio.

What was your old transmission ratio?

I'm no longer participating on SailNet.

I believe the old drive was one to one. Others were available but all the info I can fined appears to be 1-1
