Both engines can't reach more than 4000 RPM under load. I suspect previous owner may have installed bigger propellers but I have no reference for comparison. Can't find original propellers spec for that boat anywhere. Would anybody know what the original propeller pitch/diameter is for this boat? The boat will be temporary out of the water in a few days so I would like to check and compare.

Went trough "List of possible causes of low WOT" thread in adults only section and its really pointing in this direction (propellers size).

Thanks,
