Original prop size on Oday 34 with Universal 5424

Does anyone have the specs for the original prop used on an Oday 34 with the Universal 5424 motor?

Our 1982 Oday 34 came with a 15RH8 3-blade on it and another 15RH8 3-blade under the seat. However, when in gear, I get white smoke, and if I rev the engine above 2000 rpm, it overheats.

I'm trying to figure out if the previous owner over-propped the boat or if I have a low-compression or injector issue.

In normal conditions I can make about 5.5 knots at 2000 rpm with little puffs of smoke. There's no smoke in neutral, only under load (unless I really rev it up high, then I can get lots of white smoke, but I think all engines do that).

Thanks for any help.
