I see
Well a great prop but wrong size will still leave you flat, or worse, broken, you understand.

Something is amiss, continue to be patient with our inquiries, and we'll get you sorted out and undo what has been mismanaged prior to it getting to you.

A run of the mill 13x14 federal should still pull 3 footers on that boat so its not like you should need to experiment with an unproven recipe to get similarly good, solid performance.

Somethings very odd with that prop. Besides the key, I wonder about the taper in the bore.

Look on the end of your prop hub where the nut butts up against it, you might find the dimensions stamped right there.


Some have it on the other end too.

Sounds good thanks. How about the acme 425? It’s a 13x13. All the 13x14 are no longer available for some reason

You put a 451 on it it's going to frag the engine


451 that must be a case of inverse, modified dyslexia or something

You better turn the key off and hide it somewhere till you get something like Gotta Ski mentioned as a starting point to keep the RPM's down

Right I was looking at 541 prop, one on mine measures out to 11” and makes me cavitate past 6000 rpm

What's up with the stop collar?

And that's a LH prop, we determined that when you first arrived

Should be 13x14

Haha makes sense, how about a RH prop would that cause it? Print is hard to make out except for one code. Does this look like an RH prop?

Also measures out to an 11” prop.

I’m not sure I’ll have to take a measurement, but when I punch the throttle at 30 or so it cavitates. Out of the hole it doesn’t cavitate though, guessing whatever on there is wrong

In your case you need a LH prop with your 1 to 1 transmission that turns the same direction as the engine.

Not exactly knowing what you're using the boat for, I'd say you might want to do a little more research before getting a 541 with your 400 ish HP 454 in the boat

What's on it now as far as pitch and diameter?
