Default Props.

Greetings!
Can anybody tell me what was the standard set up for a Scarab III with twin 330 HP Mercruiser 454 magnum's? I bought the boat with Quicksilver 14.5 x 3 x 23P Cleaver props. I'm not an expert, but this has to be wrong skrews. The drives are TRS's, the boat is a 1983 model and it's supposed to go 50 knots +. I can only get 42 knots on the GPS, and then the WOT rev's are 5200. It should be around 4800. So, any suggestions?

42 knots sounds about right = ~ 50 MPH
5200 is to high,,but if u go with 4 blade or 24 pitch ,,i think they are going to be to big .
