Thank you for that.

It looks like an 18x16 if the D2 engine is similar to a TMD22

Unless you would like to get overloaded and black smoke or lack of speed/ power at full revs, consult your VP agent for the proper propellor. Diameter and pitch are given factors, just guessing from lists can create poor results..

The TMD22 is a very different engine from the D2 75. It runs at much higher rpm, I think 4500 rpm whereas the D2 75 is rated for 3000rpm. They use the same reduction ratio of 2.47 so the shaft speed for the D2 will be much lower and therefore a bigger diameter propeller. My calculations based on 75hp @ 4500 and 2.47:1 reduction in a 49/50 gives a 3 blade 16*10.

Do you have an existing propeller to get a guide as to size?

[breath2000]

yes and no
The propeller has no numbers and is so electrolicized that I can't determine the diameter.

The size should be stamped on the hub. Often difficult to see because of a build up of paint

Suggest you try Frank and Jimmies in Fort Lauderdale who list Volvo Saildrive propellers on their website
