Had a boo boo, prop is rubbing housing.

[sutor623]

My lower unit had the pleasure if acquainting itself with the bottom. Aluminum prop has a few little bings in it. Anyways it was doing fine on the water afterward thankfully. Got home and gave it a good inspection and when I hand spin the prop it runs the housing ever so slightly. I was pissed so to rule out a propshaft I took the prop off, spun it half way around and slipped it back on the shaft and it rubbed in the exact same spot on the prop and the housing. Did that a few times and every time it rubbed in the same spot on prop and housing, so luckily I ruled out a propshaft.

Main question, do you it's think that I deformed the prop a bit, or bent the housing upward? The skeg hit as well as the prop, but I was moving very slowly, at idle speeds. Thanks guys.

Us 'rock smackers' usually check the prop shaft by checking for any 'wobble' at the end of the shaft as it turns. Using the prop just is not as good a method IMHO.

Anyway, if the shaft is OK, then you should get a new aluminum prop.

Gotcha. Well I can break out the ol coat hanger to heck for wobble if I have to! I just figured that no matter where the prop is slid on the shaft, it runs the two exact same spots so if it were a shaft the rub would follow the shaft and not the prop itself. I need to go up in pitch anyway, so mows a good time to do it, but do you think I should go stainless? Is that whole " bend a prop not a propshaft" rumor real or a myth?

To some extent it is true that aluminum may yield enough to save the steel shaft . . . but with bottoming out, hitting rocks, etc, it is all pot luck as to what you hit, how you hit it, etc.

Ayuh,.... Yer Right,.... You can trash a drive with an aluminum or SSteel prop,...

It seems that SSteel props are just more reliable at it,...

If there's detectable wobble, at the end of the shaft,... It'll need tendin' too,...

It would not surprise me if the rubber or insert hub has been displaced a little, making the prop itself run untrue.

Yea luckily for me I'm pretty sure this is wht happened. Just trying to determine if I want an ss or aluminum prop. GOT to be more CAREFUL!!
