I don't have much experience with motors, but am wanting to learn, so I thought I'd ask you guys if this is a major fix or not. I noticed this small oil leak today while I was coved out. Its one of the lines from the oil filter. Are these easy to replace and if so do you replace just the "rubber hose?"

Not much you can do but replace the whole line since its crimped there. You can also Areoquip it, using -10 hose. Use the Hp series hose w/ the red and blue fittings. It will look cool and you'll have no more hose problems.

Probably a stupid question, but I assume I replace both the rubber hose and the metal tubing? Any suggestions on where to buy the Areoquip hose and fittings?

I have the same problem. I priced those hoses on Mercury's website and they were about $60 a piece. I wonder if I can get some braided steel ones made for less $$.
