I've got 200 hrs of wheel time messing with props and such on that set-up. I'm sure its a HO, 1.65 turning a 28 and it came from the factory that way. If you are getting a true GPS speed of 67 or better I would'nt touch a thing! Ive ran everything I could get my hands on prop wise on my 27. Nothing turns better than a 28 bravo. The only thing that you might want to try is a labbed finished 30. The HO stops making power around 5000rpms with a rev limiter or 5150. So if you can get that RPMs up on a stock 30 to 4800 or better I would labbed it and try that. Last but not least the Tachs are not perfect spot on accurate so a second mini tach is also a good idea. Good luck! Enjoy the new boat
Exactly correct. No one ever seems to invest in a way to get accurate engine speeds. Story sounds exactly like mine.
And if you go with the 30 you will have to cut it way down with stock power but if you can move just a little bit of extra water when slip goes up you will still go faster.
You can probably get it to a solid 70 depending on boat, what you have stored in the boat, fuel load etc.

Yeah... it had been a long day for me...
As soon as we got going, I realized that. When you asked, I turned around to think about the prop and it looked right at the time...
So what did you notice when you tried the 27p Hydro on your boat?
