Another ? for FusionKing

[Showdog75]

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.

If you'd like, being an ex-captain, yachet transporter, I could show you, I've been under more bridges than I've been over, lol. The run from Nashville to Knoxville is the most impressive run that I can think of. Short list of Captains that make this run.

Just do it by hand but make it as perfect as possible and make sure there is plenty of "air" between the beveled parts when you tack it up. The hardest part is grinding the pocket where the anode sits and making it presentable.
Don't overgrind the original piece or you will either have to build it back up or use bondo.
I would recommend a decent belt sander with about a 36 grit on it for making sure it looks flat and showing up low spots.
I am doing right now (I am busy again) about 4 of these a week. That is both skegs and cav plates.
Most places that sell skegs also sell the cav plates too.

Fusion: I know you and I and several others on here, have had discussions on these skeg and cavitation plate fixes before. If I can throw my .02 in: I use a die grinder and a square ended burr to shape the anode cavity after weld up. Carefully of course, as the aluminum cutting carbide burr is quite capable of chewing out some serious metal very quickly. With a bit of caution the dress up of the anode cavity usually goes well.

The skegs and cavitation plate replacement parts are available from the prop shops and they have part numbers from the engine manufacturers like Mercury, so you can get them from the outboard parts jobbers and repair shops. Recently I had a repair on a skeg from a Verado engine. One of the fellows that is a member on this forum helped with part numbers for it as none of the after market people where making them yet.

Got started today but had to pull off for a more pressing job. I think this will be a straight forward repair. A pic with my current progress. Thanks and I'll post more pics when I finish.

Some more pics.

Looks like you have gotten the hang of it.
Almost makes you wonder why you even used that piece of metal doesn't it?

This is looking good. Nice build up with the tig.
