Mo' prop woes...

Monkey Butler · #1 08-04-2009, 08:53 PM

This is a prop that I got with a used motor that I bought. It is a Gen-U-Whine Yamaha as far as I can tell. Stamped 15M and 14-1/2 x 15.

It was in almost too good condition when I got it, paint all fresh and minty and no dings or dents. Anyways after running about 50 miles and never breaking 4500RPM I never noticed anything until we pulled the boat...

I swear I didn't hit anything and the last blade with it's tip hanging on by a thread doesn't show any impact damage. Anyone seen this happen before?

I have. Most of your import aluminum props don't take well to being reconditioned and I have had several throw blades after they had been welded back on.

Yep that prop has definitly been worked on before and painted to cover it up...Aluminum does not do well in the repair shop,,Stainless may be more expensive to begin but will take more of a beating and can be repaired to original specs.... Aluminum can be used as an emergency spare to get you home

Yea, that prop has been worked on and the repairs failed. What would worry me more is that it seems someone had hit something had the prop fixed and sold the motor. I just hope the damage is only to the prop and the lower unit is OK.

I figured it could be a failed repair. Thanks for the confirmation guys.

That thought scared me for a minute but then I recalled the history on the motor. Guy I bought it from had gotten it on a 23' Grady that he bought this spring. He took it out once and the shift shaft went. I saw it while still on the Grady and it had a SS prop that he said he was going to be keeping for his the replacement motor that he was buying but that he would throw in the aluminum prop that he was getting with it. So, if this prop took a hit it was while it was on the motor that the previous owner of my motor has now. Hope that's clear as mud. I've exchanged a couple of emails with him since so I might give him a heads up.

Be sure to do several checks of the lower unit oil after running until you are satisfied that there are no water leaks in the lower unit seals. With the motor on the trailer slowly rotate the propellor and watch the prop shaft for any wobble this will indicate if there is a possible bent shaft..If water is present in lower unit, possibly worn seals or signs of a more serious problem..After checking routinely and getting the same results you will know how good a shape your motor is in...
