I saw replies in other post of a few Enertia users. Can someone measure theirs?

Could any Enertia user please measure their gearcase diameter? OR their prop hub diameter? Please.

I am running a Vengeance on my SB525. I am going to do a better comparison next week between the 15p of the stainless and my original 13 aluminum. You should be able to just look up the correct prop that you need for your motor. What are you trying to figure out?

I'ld be glad to, but what do you mean by barrel diameter? The hub or the actual inside diameter of the props "exhaust port"?

Inside diameter of the prop exhaust port, at the front of the prop (towards lower unit) is 4 7/8". Its tapered from there to the back. Hope that helps!

I don't know why this is so hard. The outside diameter of the tube/barrel the blades attach too. I have combed many documents and is not mentioned at mercury anywhere. The hub is incorrect terminology because it is internal to the prop
barrel, or maybe body would be appropriate

OR MEASURE YOUR GEAR CASE AND IS THE PROP SAME SIZE OR SMALLER. I.E. the gearcase of my 175XRi is 4 3/4",
but Trophy Plus is 4/1/4"
Thanks I hope, finally, also trying PowerTech RED3. Any experience?

BEST prop for my boat. Just look up doesn't cut it. Not from Merc prop guide for sure.

The outside diameter of the prop, towards the lower unit is 5 1/8". My Gearcase diameter is 5 1/4. its not so hard when you ask the correct question. There is no such thing as a tube or barrel. Its called an exhaust port. Its ok, you'll learn!

The outside diameter of your prop is probably 15" plus.

Right question?
Oh, learning. bought this 1988 hull in 1990, first hung hopped Chrysler 115, After burning too many pistons, went
to a 175XRi in1991. Late upgrades are Bob's machine plate, SeaStar steering, Trophy Plus prop 26P. I just learned how to go 70mph, stone stock Livorsi GPS speedo.

Sweet boat! Had a 76 Checkmate with 150 Merc when I was a kid... Wish I still had it!
Prop is still off if you need me to measure anything else for you.
