I want to mount my Mk 25 to the transom of my boat. The transom is wood with fiberglass over it. Would a rubber pad be sufficient to protect the transom? What do other people use?
I was thinking about buying this: https://www.jamestowndistributors.com/u … obot_crawl
Thanks
Jason.July 11, 2017 at 9:54 am #61407I like to use an aluminum plate that is on the thinner side, maybe 1/16" or so. 1/8" is better if it will fit. Be advised that Mark 25 clamps don’t open as far as OMC and may not fit on some boats with heavier transoms.
Long live American manufacturing!
July 11, 2017 at 10:49 am #61409I’m kind of surprised they are still making those rubber pads. They were pretty popular back in "The Day". Whatever you decide to use, make sure it prevents the motor from torquing itself off the transom.
July 11, 2017 at 12:59 pm #61419what ever you use bolt the motor on.
July 11, 2017 at 1:43 pm #61425Whatever is used, I’m a believer in the old school safety chains. I don’t bolt to transoms because I switch motors too often and don’t want several sets of holes in my transoms. A lot of older motors don’t have the bolt holes anyway; but if the motor is going to stay on the boat, and it has bolt holes, yes that’s the best way – my pontoon motor is bolted on.
DaveJuly 11, 2017 at 3:39 pm #61433I bolted a 12 by 2 inch steel bar plate which had a small " lip" on it’s top edge .
I figured it would stop the motor from slipping of the plate if ever the screw pads came loose.
you can make one by trimming down one side of a piece ce of angle iron
if the lip interferes grind a passage way flat for the pads and slip the motor sideways against the lip section or slide the motor sideways from the edge of the plate and guide the pads below the "lipped" section

Would stainless steel work?July 11, 2017 at 3:59 pm #61437well it won’t rust and it is better than punching holes in a soft transom !

July 11, 2017 at 7:04 pm #61443I use 1/8" alum on both sides. As stated above make sure what ever you use the clamps open wide enough.
July 11, 2017 at 7:10 pm #61444I have one of those rubber pads on a Thompson wood boat. It has a piece of aluminum on the inside and the outside of the transom to protect it from changing motors. When I ran my CC Commander on it, It had some vibration noises at certain speeds, mainly at trolling speeds. i’m hoping the rubber pad will eliminate that issue. The motor seems rock solid with the rubber pad installed, but I have yet to water test it.
