Any suggestions for an anchor to use for my 150? I bought one from WalMart, but it is a 4 prong style and I think a Mushroom may be better as for storing it on the boat without causing damage. Also, what is a good method of/location for storing it so that it does not damage anything? I don't know how thick the hull is and thinking of it bouncing around in the ski storage area or engine compartment as well as on top of the compartment cover makes me kind of nervous. Any tips?
