What gear ratio are those things?? That seems like a lot of prop for a 40hp
Agreed... Considering my 60 merc only spun i believe a 16 chopper. Maybe it was an 18 but i dont think so.... On a voodoo. And it ran tits imo
There was a 60 merc on that voodoo when I got it and he was running an 18 pitch chopper on it. Those mercs have a ratio of like 1.64 or 1.67 or something like that. The OMC's (40 or 60) are 2.42-1. Gonna be way different for prop. 18" on a 60 merc would be like 23" on a 60 omc (just guessing) and the 40hp will need much less than the 23 I'm sure.
