I don't remember ever seeing anyone mention line cutters for their prop shaft seals so I wanted to mention it here. Apparently they are not considered stock equipment, but they are available for almost any lower unit including the older Volvo Pentas. Probably many boaters who do not fish don't really think about making sure they have them, but after talking to my mechanic friend they are a great and cheap form of protection from the fishing lines that can float. Just thought I would mention this and the importance of magnetic drain plugs in lower units since I discovered water in the lower unit of my 250EFI outboard on my Donzi 23' CC last week when doing some maintenance. It had no line cutter or magnetic drain plug.
