Suggestions on which prop size should I use running a 5.7 sbc in front of a volov penta 280 (1984) In a Bayliner Trophy FG model 2459. 3 or 4 blade to reach max WOT.
Question: Would a broke spring located on the shaft pin on the portside of the retaining pawl mechanism cause the outdrive (280) to cavitate above 2000rpm?.:confused:
