Did I spin a prop?

[63chaos]

Took advantage of a great July day in October yesterday, It’s the end of a long season the outdrives are covered with barnacles and crap! When I powered up the port engine RPM’s went way up to 4500 and the starboard was at the typical 3000 – 3500. It was difficult to get up on plane and could not get the speed I usually get. Did I spin a Prop? They’re nice stainless steel props, no sure what kind?

Are you sure that the prop is still there ??.

I had one come off while crossing the lake :wow:.

Ya It's still there, Can you spin the hub on those SS props

Im not an expert by any means but when I broke the hub on mine I couldnt go more that 5 knots, none the less get close to on plane.

I didn't have ss props so I don't know. I guess anything is possible.

Can you put a mark on the hub/prop then put it gear to see if the mark has moved.

I'm not much help to ya but trying. :smt001

No thanks for the input I'm an electrician not a mechanic so any advice is greatly appreciated. I seams like the starboard engine was doing all the work. Is it possible the prop is slipping under heavy loads.

Yes it is poss to spin a hub on a ss prop. each case is different as far as when the prop will spin on the hub. Fairly cheap fix when you pull the prop and replace the hub.

Yes, I had a prop do that before.

We spun the hub on a SS prop on our last boat. Took both of them in and got both serviced. Think the bill was under 150.

Thanks for all of the info everyone, this is a great site. Its a sad day when you know the next trip on the boat is to the landing when it will be yanked for the season. But 2011 has been a great boating season in Falmouth and the islands. Can't wait for next year. I will have both props serviced.
