Prop for my V

smkinnan · #1 05-18-2011, 12:59 PM

ok, I've read and read about the proper porp size for my V. I need a little help because it is all so confusing. Here are the details, best I know. Any help would be appreciated.

Standard V20 Center Console
Evinrude 150
WOT = ? unknown (Ferm or tsubuki might be able to help on this)

I don't know what else I need to supply to help.

I'm running a stainless 14x19 but only get up to 5000rpms at 44mph wide open. A 14.8x17 aluminum did the same numbers. I'm also lightly loaded and only a 40 gallon fuel capability.
Depends on how you tend to load the boat fuel and bow monkey wise as to what might be best.
A load with a couple of guys (non MJ size), 60 gallons of fuel, their food, drink and fishing stuff might do good with a 17 pitch stainless.
Now if you got a couple or few MJ's and a lot of stuff, you might need to go down to a 15 pitch.
I'm still dragging my feet as to getting mine tuned in correctly, I know I need a smaller pitch.
That motor did 5000rpms and 42 mph with the 14x19ss or 14.8x17al in my situation.

tsubuki, do you remember approximately what fuel comsumption was? Just wonderin'...and thanks for the info. Ferm looked at the prop when I had it there and said it was way too much but I couldn't remember what he told me to get. I think the stainless I have on there now is a 21p :(

Do you have a working tachometer?...what prop now on motor....what RPM at present?...I agree w/Genie on pitch (17) but believe these deep Vs need more blade, so my vote is a 15 X 17....make it SS if you can...

tsubuki used to own this motor and he said 5000rpm. I assume thats WOT!?! Not sure if that is what you are asking or not when you say "what rpm".

btw, where is the best place to get a prop?

tsubaki · #8 05-19-2011, 02:48 PM

I'm partial to Michigan Wheel stuff when buying new.
Craigslist will on occasion have good used OEM stuff in stainless say $100 or less.
That motor takes the same as the 2000 I've got, 15 spline.

This was the 14x19ss and 14.8x17al fuel burn numbers.
5000rpm-42mph-19.5gph-2.15mpg
3800rpm-30mph-10.5gph-2.85mpg
1250rpm-5mph - 2.5gph -2.0mpg

I'm not sure what the WOT rpm's are supposed to be for that engine. I just know I never achieved them with these two props.

Might be able to talk these guys into a swap. If not it's good to know people that do this work.

We can fix your prop. We offer reconditioning of ALUMINUM PROP'S for $40 to $75 and STAINLESS STEEL PROP'S for $75 to $250 including welding if needed. We can help you increase your fuel efficiency and go faster. You don't have to buy a new prop when I can fix your current prop for the price of a new one or less. We have boat service as well. We offer skeg repair and we sell Stainless Steel,Offshore, Flats and Bass boat props. Summertime is here and we want to keep your boat prop in good working condition. So if you need a prop or boat fixed CALL OR BRING YOUR PROPELLER and/or BOAT to 24700 E Highway 50, Christmas, Fl 32709 or (407) 568-5506 and ask for MIKE.

thats awesome information....how did you calculate this? How do you get "fuel burn" numbers? And thanks for the link, that place is right down the road here ;)

If I decide to go new, where do you usually buy?
