Mounting William Racing Motor Mount CC 2028 Help

[Biscutz]

Hello,

I need a little advice on mounting a William Racing Aluminum Motor mount for my Cast 2028. I will be installing this in a 47" deep v. My concern is getting the aluminum mount to stay put with epoxy. I was thinking of reinforcing the hull as well while I am at it. I went ahead and drilled a bunch of holes along the base of the mount and I plan on scrapping the base up with 60 grit sandpaper. Is there anything else I should consider before I glass/epoxy this thing in? The 2028 is going to have a lot of torque, so I want to make sure the mount stays put.
Thanks.

Give the hull a good scuffing and clean it all with degreaser, I've changed to JB weld for mounting motors, killer stuff. Mounted 4 or 5 now with it, no problems.

[Biscutz]

Is there a type of JB weld you have used or just the standard stuff at HD? Should I make sure it gets through all the holes I drilled on the bottom of the base?

Which William’s mount is this? All of the mounts I've gotten from Jim us fasteners of some sort (i.e. through the bottom of the hull or onto a couple of rails in the hull).

Later,

Mike,

This mount does have screw holes at the bottom, 4 to be exact an all four corners. I was planning on using epoxy to fasten the mount to the hull. I really didnt' want to use wood if I could help it but if it makes more sense I can do so.

This is my personal opinion, but I ALWAYS avoid bonding in a motor mount. I would reenforce the bottom of the hull....

Nevermind, I just noticed that you putting this in a mono hull (deep vee). I would much rather have a couple of nice wooden stringer in the hull and us a rail mount system rather than glueing in that huge chunk of nicely machined aluminum... Buy, hey, that's just me.

Good Luck!

My very limited experience has suggested a problem with epoxy bonding to a reinforced, CF/Kevlar lined hull. Seems as if the additional items have a difficult time bonding to the hardened epoxy. Obviously everyone here has done this with limited or no problem, but I would like to come up with a better option. I am beginning to think that the rail system may be more reliable. I think I am going to attach all mounts prior to hull reinforcement on my next build. The as shipped hull has a rougher texture and I am wondering if the other items will be more secure this way.

All you need to do is scuff with sand paper the hull ware you want the epoxy to stick. A rail system will eliminate flex if it goes all the way to the transom in a mono.

the slow drying JB weld is stronger than the fast drying
