Stainless Prop and Sand
Quick question: coming into my beach today my stainless prop hit sand for a second or two before pulling my motor up--should I be concerned? I always hear SS props are unforgiving. I looked and couldn't see anything different, not even a "shinier" spot.

no problem. SS is very forgiving of such things.

The drive shaft can be damaged with prop looking ok. Hope not, but just mentioning, not forgiving.

One can do a fair amount of roto-tilling in sand at low power with nothing getting damaged.
If your personal paranoia is seeking a new outlet, I suggest getting the prop shaft run out measured via a dial indicator after your season is over. I would not do so. |

Last time my kids did this on our Four Winns it was $700 for:
"labor to pull lower unit.replace Inner propshaft, reseal, reshim, put back on boat and lake test." They noted vibration on inspection. |

I'll be taking it out again next weekend and will pay close attention to vibration. It was really deep, soft sand (as opposed to a thin layer on top of hard pack), so I'm hoping I'm OK. Thanks, all!

I assume you were at or near idle speed, if so, and there was no "BANG!" or "CLUNK-CLUNK-CLUNK", there's really nothing to worry about; especially if the engine did not stall, ut if it did stall that's not necessarily bad.

You would notice vibration if you damaged the shaft. Also, how do you know it was the propeller that hit and not the skeg?

I boat on Cape Cod that has a LOT of sand. I have run through sand a zillion times with no damage I wouldn't worry about it.
However, a couple of times were to the extreme and clogged the cooling system and I had to disassemble the hoses to clean them out. Not fun. But really, unless you have vibration or your "engine overheating" alarm going off, don't worry, be happy. |
