Propeller selection info and speeds

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

Ha! She's 20 weeks pregnant with our 3rd boy - I'm picking my battles wisely!

[Big Block Power]

Liquid what did you get? I never heard the results. You disappeared for the end of summer.lol no internet or cell up there?
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.

I got an update on this but it's a looooooot of info. Will post soon.

[Ytmsn]

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

[Big Block Power]

Yea he's in his place just relaxing and us hanging. Prob doing more research. Maybe by next year:-)
Just BUY one damit. Lol

[liquid]

Hahaha! I just reread the entire thing and couldn't believe i left myself hanging!

I was like "what the f, self?"

YT - long story short I kept the 3 blade aluminum that Cobalt recommended. The 4-blade was good but I can't explain it, just didn't feel right. My brother thinks I'm crazy but I notice different things than he did. he says it vibrates more with the 3 (even though it's unnoticeable to anyone else when trimmed properly) in the mid range. It turns better with the 3. The wake is better with the 3 - don't know how to explain what I mean by saying that.

The hole shot was not noticeably different with either. The kicker - the 4 was a little bit faster. consistently 49 on gps is slight chop with two guys and a half a tank. 3 was 47 - 48 on a different day with same conditions.

Double kicker - I couldn't get to 4800 RPM with either. 4300 ish on both. I was perplexed a little bit and ran out of time last summer so i went the path of least resistance and stayed with the prop Cobalt recommended. Then I had a baby. I still want a prop but I want a prop that someone has used successfully on my set up. Enter Fozzy. Time to Frankenstein this thread in the 190 section.

Also the 4 blade was a little wonky for docking.

Still confused Oscar. Did you buy one yet?

How do you tell what pitch prop you have? I don't think mine is stock beings it's stainless.Is it stamped somewhere?

Yes it's normally stamped on the barrel of the prop or on the end of it where the nut goes. Not YT either a nut that holds the prop on.pictures if you find them we'll help you once you find them.
