Motor mount area.

[Boris]

Pulled the motor out of my ski yesterday for a general cleanup and to survey the 3 new holes I made in the bottom after collecting some rather large rocks (had a blast just the same).

Anyway, my motor mount perches (those raised areas with the inserts in them) are looking rather rooted.
They started to ware away some time ago when I had some AM motor mounts that worked them selves lose and things are getting worse every time I check.
The right front one has about a 1/4" of material already gone and even the brass inserts are starting to disappear. The others have groves dug in ranging from 1/8" to 3/16".
I grabbed what I had on hand (JB Weld and some liquid nails) and filled in the voids which might work for a bit but what would be a more permanent solution ?
Glass in some metal plates ?
Guild it back up with some resin ?
Start transplanting all my stuff into my other hull ?

Engine alignment is starting to be a peal pain with the motor mounts being lower and lower.:laugh2:

Here is my solution... Each motor mount is about 5" long x 3" wide (with extra to spare). Grind down each of the mounting pads. Buy some 6061-T6 aluminum bar stock. I'd say buy some 1/4" thick x 3" wide bar. It'll take 2 ft of bar to redo all four mounts. I'd say buy the "random lengths (10"-12") and just cut in them half to make things easier and save a little money but a regular 2ft bar is $7 so it'll be cheap either way. Drill and tap the new plates and line them up. Once aligned, just epoxy the plates down and put a layer of glass over top. Now you have brand new mounting pads made of aluminum and it probably cost less than $20 in overall materials.

Here is a link to the metal.

The aluminum plate idea is what I was thinking about for a more permanent solution. Actually I was thinking of using stainless as it handles salt a bit better.

Right now I'm just going to booger it up with JB Weld and see how that holds up. This hull is starting to show it's age so I don't mind experimenting on it.

If you're just looking for more temporary solutions, what about some hard plastic from lowes or something wedged between the mounts and the hull? As long as the inserts are still there, it shouldn't be an issue.

Stainless steel would be nice (maybe a little overkill) but I can't tell you how much I hate cutting, drilling, and tapping stainless.
