Re: [OMC-Boats] Prop for 1970 Evinrude Sportsman

The prop that came with my boat but not on the outdrive is a 381186 14x16 which appears on your list.  My prop had been damaged and the shear pin broken which might partly be a clue as to why my outdrive is not original to the boat.

The prop off of my 1970  has the number 381187 and 14 x 18.  The michigan prop has 012092 which is a 14 x 16. I was unable to locate a michigan 012093 which is a 14 x 18.

Thanks,

Bill

I'm guess here, but I think what you've both run into is the issue we've been discussing at length.  Pre XXX-16C model  (4-cap covers) OMC drives (approximately mid 1967) have different prop requirements.

I've never been totally sure about the Michigan Wheel props, I always assumed they would work in either 4-cap (early) or 5-cap top (late) drives, but it could be they only fit the early pre 67 drives.

DO each of you have your prop part numbers handy?  I have documented these prop part numbers here:  http://hhscott.com/evinrude/props.htm

Interesting you should say that as I had a similar prob.  I replaced the prop with a prop that had the correct prop number but it felt funny going on and would not slip all the way down the shaft.  After having exprienced difficulty getting it back off the shaft with just the merest of hand pressur, was afraid that if I forced it, I'd never get it off.  I took the whole boat to the prop shop and found that while the prop number matched, the shaft was not correct.  They recored the shaft with a new one without the flanges you mentioned and it fits snugly onto the drive shaft.  There in ever so slight give rotation wise that I'm a bit concerned about as though the pin is not as snug as it should be but a buddy seemed to think it was fine.
 
So, I guess in adding to your concern, now much rotational give should there be with the pin?

I replaced my original 14 x 18 prop with a Michigan wheel 14 x 16 that doesn't have the two flanges on the inside like the original.  It seems to fit but has more play in it than the original.  I haven't used it yet, wondering if I have the right one.
