I've got another marina repair I thought you might could give me some insight on. It's a lower unit[foot] that has a broken piece that I'll have to make a new piece for. The piece is gonna be the area up to and around the anode and I was curious if this is something you'd have to have machined to make fit just right or do it all by hand. I plan to use a piece of aluminum that matches the thickest portion of the area and blend it with a 4 1/2" grinder with a sandpaper disc.Sorry I can't take a pic tonite but will first thing tomorrow. A pic will show you exactly what I'm talking about if you don't already.
