I just recently purchased a 14ft aluminum V haul for a very good price. The boat came with a 6hp sea king motor that starts right up. However, when I start the motor up , the motor runs and I can increase the throttle to fast but the prop does not spin. I have made sure that on the left side of the motor (if your looking at it from the front pull side) that it is in forward gear, but as I clicked the gear from forward to reverse I finally had some feedback and the prop was slowly spinning but not nearly what it should be spinning at. After I tried this, I pushed the gear back to forward and the gear lever now completely spins in a complete circle acting as if something has given way or has fallen off inside the housing, that is connected to the lever. I can somewhat get the prop to spin now but it seems to have a mind of its own. Can anyone point me in the right direction of what this could be caused by and what I would need to do, if I can do anything to fix it myself? I thought about unbolting the lower unit from under the main head to see if it will expose anything but I figure I should ask first before I mess something up. Thanks for your time!

Sounds like a shear pin has sheared. Take the cover off the prop hub, and take out the pieces. There is a pin that goes through the drive shaft, made out of brass. This holds the prop to the drive shaft. Yours is probably either missing, or sheared. They are available nearly everywhere. Take yours into the shop, and they'll be able to sell you more. Get a bunch, and keep them in the boat.

The point is to protect the drive shaft from a stuck propellor, or a sharp prop strike.

Re: 6 hp Sea King motor issues..

Any idea about why my gear lever can spin in a circle? I have no say of what gear it is in, if it is first right now the only way I would be able to tell is by which way the blade is spinning. Should I go in there and mess with the gear rods?
