shaft diameter 8/71N and 8/71ti

[MarioG]

Pascal is lending me his props to have as spares for a trip to the Bahamas. the question we have is that is there a shaft dia. difference between 8/71 naturals and 8/71ti? i have 2.00" dia shafts. i think the N has the same 2.00" shaft dia but different pitch.

I checked, they are 2" shaft. 28x 28 4 blades, assuming they're the original spec'd props... I never used them so i'm not sure if that's what they are... Pitch has to be different between N and TI but but they will get you home...

dont' come too early, we're going sailing this afternoon... i'll need a hand to get them out, will probably need to pull the dinette table and open the stbd hatch.

I believe a 1970s 53MY with 8V71TIs was spec'd with 2" shafts and stub shafts and 28X31 props.

you can just go into the engine room and measure the shaft.

Although I think 2" is the likely size for both.

I have an extra set of 28x28x2 4 blade props for sale if you are interested in having your own spares.

Mario,

Our 53 MY has 8V71 N. Swinging 28 X 28 on 2 inch shafts.....

Interesting on the pitch. Our '72 48 Yachtfish has 28X27 props. According to the owners manual that is what was originally put on the boat. Seems that a 53 would have less pitch than a 48.
