Bottomed out Tahoe, Prop wont turn anymore.?

Question

I have a 2004 Tahoe Q4 Ski/Fish boat with a Mercruiser. I was about 15 yards of shore fishing when I decided to go around the corner quickly. Anyways I got half way around and I bottom out the boat and hit the engine. My motor runs and shoots out water still but my prop doesnt turn. Anyone know what I possibly did to it?

Answer 1

can you shift it into forward and reverse, same as before?

when you give it throttle in gear, does it rev but the boat don't go?

paint or scribe a mark across the inner prop hub and rubber bushing, put the boat in the water (don't bother taking it off the trailer), put it in gear & rev it up.

If the mark on your prop is still lined up, then you got bad problems, the gearcase has to be torn down for inspection.

If the mark no longer lines up, remove the prop off & take it to a prop shop.  They'll re-hub it for ya, not too expensive.  (or the flo-torque thing like jim said).  This is the most likely scenario.

I guess we all learn eventually that the depthfinder is not an "early warning" system...............

Answer 2

Shear pin is broken .  Pull the prop off and inspect shear pin replace if distorted/sheared. Mercruiser is vey relyable and has this feature. They are inexpenseve, costing almost nothing compaired to a hole in the bottom! Watch the bottom!  No pushing mud!!! err rocks

Answer 3

I hope you have boating insurance.  From your description, I understand that you can see exhaust coming out of the prop, and it's not moving when you put it in gear.  So, I don't think it's a spun hub.  It's probably a broken drive shaft.  I'd take it to a good mechanic and have him check it out!  Good luck!

Answer 4

Do you still have a skeg?  Is there damage to the prop?  If so, you might be lucky and have spun the prop hub.  On an 04 it should have a flo-torq hub, you can change that  yourself.  Take the prop off and have a look, damage will be self-evident.  If the hub is OK, you have internal damage in the gearcase, phone your insurance agent and take it to a dealer.
