Sunsation 288 SSR Prop Recommendations
Hello
I have a 09 Sunsation 288 SSR with the 496 HO. I am thinking about getting a new prop and would like the groups input.
I am running a 24p B1 prop. RPM vs Speed info is below. Boat weighs about 4500 pounds. I usually keep the fuel tank full so assume about 90 gallons of gas in the tank plus some gear. So maybe another 1000 pounds for a total weight of about 5,500.
RPM----------------Speed (MPH)
2000 RPM---------12.5 mph
2500 RPM---------20.5 mph
3000 RPM---------27 mph
3500 RPM---------37 mph
4000 RPM---------50 mph
4500 RPM---------58 mph
4850 RPM---------64/65 mph
If I trim the boat more I can get up to 5150 RPM (Rev Limiter). But I will lose a MPH or two.
Time to plane if I use the Tabs is about 8.7s and if I don’t use the tabs it takes about 10.6s. The prop does cavitate for an instant when getting on plane. It happens when the nose starts leveling back out again.
I have googled props for the 288 a few times. Seems many would agree that the B1 props seem to be a good combination for the boat. I have also read that some guys run 26p and 28p.
Past owner has said the boat would go 72mph. I have read some others get that speed. Have also read that others run more like 68-69.
Wondering if it is possible to get in the low 70s with a prop change?

I believe the 288's came from the factory with a 26P Bravo 1.At least that's what mine was set up with. 496HO you should be seeing 68-70MPH.
I have an 05 288 MCOB. Pulled the 496HO and stepped up to a 525EFI, running a 28P Bravo 1. Boat does 78-79MPH all day long.

Thanks for the information.
I talked to the factory. They told me that the 496 HO boats came with the 24P and the 502 boats came with the 26P.
I wonder if the 26P would get me a few more MPH if I could get to the same RPM. Seems mid range cruise would be faster if I look at the math right.
