The boat in the picures below was a carbon copy of mine.

The only 2 differences were the barefoot plates (Mine is HYD and his was Manual) and the props.

The way the 2 were propped his would spool up faster out of the hole, I had more mid range power, and he had more topend.

The second picture is why I can simply just see what was being used on that boat. All any of us can remember is that it was a 3 blade prop.

13.7 x 19.5 is the one I like the best.

It seems to preform better than the other 2 but the big difference I see with it, it does a lot better on fuel.

Sorry for the thread jack

Eric, I got a '93 ps190 and I'm turning a 13.7 x 17.5 four blade at 5100 ish rpm at 47 mph on gps stargazer. Can I turn a 19.5 or what do you recommend.

The second picture...
Yes, looks like a big pile of carbon!

Don't think that will buff out though...


Johnny-Where you been at these days for work?

48.5 @ 5100 IIRC

I will have it out in a couple of week and take note of some various speeds/rpm.

The 2 pieces of the puzzle that you need to supply are:

1) Where does your boat make its peak hp? (I would expect a NA 6.0L to peak in the 5400-5600 range... not sure if/how the SC affects that).

2) A known data point (WOT RPM vs. GPS speed with a known prop).

Then you prop it to turn at or near the peak hp level at WOT. That will maximize top end. If youre currently overpropped (which may very well be the case) then if you go to a prop with less pitch, you should gain holeshot, midrange power and top end as well.
