Hi all, this is my first post and I am new to boating and do not know anything about props. I have a Blue Wave 189T, Yamaha C115 (w/Stingray), PowerTech M90PFB4P16 prop.
During rough conditions, I can't get the boat on plane. But when it is relatively calm, it will be about 3000 to 3500 rpm at WOT and then rev up as the boat slows almost like the prop cavitates. Also, in reverse, the boat will not go even as I increase rpm.
The prop is a stainless 4 blade 13"x16". I think I need a 3 blade 13.5x19 according to yamaha's website but any help would be appreciated.
