    should I just smelt it down and make sinkers?

    No interest all summer in this prop, should I just melt it down and make sinkers from it?

    Chortle , might be interested , may be more wheel than I need. what diesel you running, a 3208?
    I will need to confirm shaft size this evening, I think its 1 1/2''.
    it will be on a 36' wood boat with a 460 gas w 2;1 gear.

    See link for the data I reported with my repower from a Cat 3160 210 hp to a Volvo D6 330 hp, maybe this data will help? I also still have my old 21x18 1-1/2" bore Ellis bronze prop that came with the boat. It was overpropped for the Cat, but I think the load per blade would have been too high for the 330 hp D6, don't know how it might work for you but likely the same issue, too many hp for the blade profile.

    I've got a 21x19" three-blade on the Nauset, seems to be the perfect pitch for the 350hp 3126. Wouldn't mind making it a spare and going to a four-blade if I wouldn't lose RPM; currently turning 2900 at WOT (rated at 2800). Plenty of room to swing more diameter compared to a standard Bruno 35 so that's not an issue.

    What's the conventional wisdom with inboards? With I/Os I always had to drop at least an inch of pitch to go from 3B to 4B. Is it the same on these?
