Replacing motor mount
« on: February 16, 2017, 08:50:07 PM »
Hello,

I need to replace the wood on my com-pac 16's motor mount.  Is marine plywood the only way to go or are there any other options?  One of the sailors in my neighborhood says he actually cut a think plastic cutting board and it's worked well.  I like the idea of non-wood but not sure about a cutting board. 

If I use marine plywood, does it have to be treated at all? 

Thanks

The stock mount on my 23 has some type of polymer material, not sure what it is.  Probably acetal, HDPE or UHMW.  You can usually find small pieces that would be appropriate for a motor mount on ebay.  I would suggest UHMW if you have standard woodworking stuff to cut it with.  Be careful about chip removal when cutting with a table saw it will bind up the innards in a hurry.

Marine plywood, depending on the type gets that designation as a result of specifications that limit voids in the laminations, surface imperfections, and because it has a waterproof glue used to laminate.  That does not make it impervious to water unprotected.  If used, it should be sealed with epoxy then coated with the UV resistant coating of your choice.

Com-Pac yachts home page has a link at the bottom the page for "Parts List"  They have the following for the CP16

Part # RA00M0132  Poly Board for Motor Bracket   $45.90 each.

I don't know what you were expecting to pay but you can have confidence that you are getting the right thing when it comes from Com-Pac.

Thanks Jeff. That might be perfect. From what I've seen, marine plywood isn't cheap, plus the time to construct it.
