Can't ID Prop. Have #'s, but, they match nothing. Came off an Evinrude 140 V4 1994

[cerenzio]

I have an Evinrude 140 V4 1994 (I believe it's a 94). The guy who sold it to me and installed it, put a random prop on it It's a mess, and needs to go. Trying to decide on a new prop. I have used this prop for 3 seasons, but my TACH is not working. So I don't have #'s, but, I at least have a feel for it's performance.

I need to know the props pitch, but, I can't figure out how to determine it. I've Googled till my eyes bleed.

In 2 places it says: A155150

in 1 place it says "Vinnie"

I believe it measures at 15" (I've done my best effort to measure correctly). Could this be 15x15?

I can't find this prop # online anywhere. I've tried every combo of those #'s, even replacing 0 with O. Etc.

Can anybody make sense of these #'s? The word "Vinnie"?
.
I know PITCH is a lengthy conversation, but, can anyone at least recommend DIAMETER. Is 12' small? It's on a Stratos DC-200. 19.83 feet.

My #1 question is: What PITCH is this sucker?

Thanks a bunch!

Here are the #'s on the side. same number is inside

 

[cerenzio]

No Title

Does the prob Diameter look to big? Should I go smaller? The boat is an hour away, hope to find a better picture of the prop, mounted, to share.

If I had to venture a guess without any of rpm and pitch information on this prop I would think you should be around 14.5 x 19 or 14.25x 21

Thanks so much! I will have a look at those. Any guess on how to decode the #'s on the current prop, to find the pitch?

Does it say anythting on the side of the prop

 

[cerenzio]

Yes, I posted a photo in this thread. It says A155150 and VINNIE

If you look up props here for a 140 I think a 15" pitch is a good starting point.

Thanks for your input. Would you say the 14.5x19 is not a good idea? As suggested above? Any clue what my current prop is?

I think I'm out of luck ID'ing this prop...

From the looks of that prop its time for the scrap pile. I would pick up a new 19 pitch and go from there

 

[jimmbo]

I think a 17 would be a better choice

 

[flyingscott]

Call a dealer they can recommend a prop for your set-up.

A working tach is a must to get the right prop size dialed in.That looks like a heavy boat,i personally would start at a 17p.

I've got a 14.5 X 19 on, and will give it a test run. Sadly, nobody can ID the old prob. We'll see how a 19 does...

I Agree. I have not been able to identify why the Tach no longer works yet. It did prior to a motor replacement. Hope to nail that down soon. Will be water testing a 14.5x19. I got pretty varied suggestions, and with no idea what pitch my current prop was, I took a shot at one of those suggestions. Thanks for your help. If 19 doesn't work out, I will try lower....

How did the 19 work for you?
