Hi guys,
I need some help and advice with my prop problem. The boat is 1998 Bayliner Ciera with a 5L Merc and Alpha 1 drive. I bought it two years ago with a 14 ½ x 17 three blade aluminum prop. It has been working OK, but my WOT is just above 4000 rpm and I have been having problems getting on plane with more then four people. I thought that going to a 14 ½ x 15 would give me an additional 400 rpm at WOT and make it easier to plane, but I was in for a big surprise. The boat would run OK on low rpm, but the prop would spin every time I tried to increase the speed. What went wrong? Did I reduce the pitch too much or is it the OD rather than the pitch problem? Any other possibilities that I am not aware of?
Thanks,
Andrew
P.S.
Anybody interested in a brand new, original, 14 ½ x 15 Mercruiser Vengeance SS prop?
