I say get the power tech 4 blade. I know nothing about that line of props. I love the rev 4 but not sure you could turn it good enough. I ran the high 5 loved those props. I would buy that aluminum 4x19 on cl it's cheap for a spare

I already have the 3 blade 21, dealer will exchange for the 4 blade 19... point is if it doesn't spin well I'll be a jackass if I go back and ask them to exchange it again....

So i"m left with keeping the 3 blade for the summer and getting the SS 4 Bade power tech in a bit once my wife forgets the word prop... or switch out the 3 for the 4 with the dealer and hoping it spins well.

It will spin the 4x19
I'll see if there is a high five out there too. But not sure if a19 or 21 on that. Did prop god give you a pitch on that?
I used to only run a high five till I ran the rev 4 I had another buddy that has a rev try a enertia and loved it. He has a 350 carb 4barrel. My other buddy is running that 17p rev has a 5.0gxi and is happy with it. The good thing with those props which I did is buy them cheap on cl and if they didn't work I just sell them again. They are very common props. I also ran a 21p vensura you could prob spin a 19p that was my 4 blade speed prop. Held water great good hole shot and still great top end.

Just a few I found. Not sure how a rev 15p would be, but you will get one Heck of a launch and mid-range.

Thanks BB - truly are going above and beyond. Talked to my dealer and they're going to let me exchange a few props here as figure out what i want.

I'm giving them useful data to begin with so as long as i don't mash the props should be good.

So here's my plan:

Going to run all three props in the same conditions at WOT and figure out RPM and use an independent GPS Speedometer app.

14.3 x 21 x 3

14 x 21 x 4

14.25 x 19 x 4

All OEM Volvo props.

Once I find my sweet spot and then Find my SS!

That's cool they are willing to help you. Maybe try to time to on plane time as well as speed. I always play with mid-range punch as that's where you boat at allot. Props perform so different at different rpms. I always figured a 21 stainless will perform like a 19p alum at hole shot and like a 23 alum at top end. That's just one of the advantages of stainless.you have to get one mounted. Your killing me :-) yell the wife I let you use one of mine for the year.lol

I just ordered these yesterday for the new to me boat. I love boat bling :-) She's going to be a rocket out of the hole and great mid-range. It will be neat to see what wot does.

Liquid, seriously? I read this en tire thread, and when I got to the end you just left us hanging...
