I was running long at about 2500 rpm and an excessive vibration started shaking the boat (95 Maristar). I shut it down checked the prop/rudder - everthing was fine. Started up again and it was smooth as ever - no problems. When I pulled the boat out of the water I found some yellow nylon pieces stuck to the prop nut and one arm of the cotter pin was broken off. Appears I hit some nylon rope. Because of the short period of bad vibration is there anything I need to check before I put it back in the water?

I wouldn't worry about it as long as all the line is gone.

Replace the cotterpin?

Should be fine. Another reason to own an inboard. My buddy wrapped some of that stuff up in his I/O, which damaged the seals. All his drive lube leaked out and fried the drive before he know about it. $2000 repair bill.

But if you do wrap a rope around the prop/shaft, it can be difficult on a inboard as you have to dive to get to it, at least a I/O or outboard can be lifted out of the water to make it easier to remove.

That would be why I keep a diver's mask and sharp knife on board.

I know some of you will say "DUH" to this idea but 4 times I have seen people untangling lines caught in the propeller. A mask and knife helps a bunch but if you remove the platform you can reach almost everything without to much diving under the boat.
