I'm terrified to try a pitch higher than 19. I have tried a 4 blade 17 pitch as well as a 3 blade 17 pitch (I'm now running the 3 blade 17 pitch, I haven't tried getting up behind it yet though).
The 4 blade 17 pitch seemed about the same holeshot as the 3 blade 17 pitch, but a little slower...
Well, turns out the vibration I'm getting is due to cavitation. It's putting cavitation burns on the prop.
Prop guy wonders if the prop sits too low in the water. His theory makes since. This boat you can't hardly even use the trim unless you're going below 10mph.
The reason I'm using a 15...

I was wondering if...
I think it's actually a 15.25" prop (for the record)
This does have the catalytic converters.
Also, the soot is something I just noticed after the visit to the dealer. I will show them.
On the vibration, it doesn't happen with other props. I'm taking this prop in today for an inspection...
I am noticing a little carbon build up on the propeller shaft, is that a problem?
Also, I do get a little vibration at certain rims. I think around 2k, wondering if the propeller has bent or something. I do see a little paint peeling off...
2025 bayliner vr5 with about 55 hours on it.
4.5 liter 200hp mercruiser with alpha one stem drive.
I've been trying different props to pull me up on a slalom ski. Finally got that going well after 4th prop.
This is a 15" 15 pitch 3 blade EMP propeller. Boat goes 39.5 to 40mph at around...
Also, to address a couple of people's comments.
When I took to the dealer, they checked for codes and engine issues, none found.
The swim deck has drain holes in it, I do see water draining from them often, so water does get in there... not sure if water is getting in from those holes...
Ok everyone, I'm hesitant to believe the issue is resolved, however, I have very positive news.
The dealer installed the se300 hydrofoil I bought (I paid them), and had them change the oil and other recommended 100 hour service even though it was at 45 hours.
So, it pulled me up on a...
Saying put a hydrofoil on it and/or trim tabs. They're putting the SE300 on ALL their VR5s new. warranty isn't covering anything to do with this weakling boat. even with the 15 pitch prop it has trouble pulling my 180lbs son up on a slalom (he just learned though!).
Lastly, Bayliner did...
Supposedly, but bayliner keeps telling me I need to talk to the dealer that sold it to me.
Otherwise, I'll have to spend a few hundred $$ for debug/diagnose or what have you, and they may say it's fine engine wise. Though what happened yesterday made me wonder.
Regarding the ski I have...
