I just bought a '82 C25 and saw that the engine mounting bracket has no backing plate (just four 1 in. washers). Is a backing plate recommended? Or the washers are fine? BTW, I have a 9.9 hp Evinrude that weighs about 90 lbs. Thanks for any recommendations.

I have been worried about this same thing. I was planning on making it a Winter fixit job, but didn't get to that one on the list.

mqp,
Have never heard of a motor bracket without a backing plate. My guess would be that it rotted and came off. They now make backing plates made from poly-plastic materials.
At 90 lbs you're in for some real exercise if it's the original Catalina bracket which I think you'll find unacceptable. Can you give us some additional description of the bracket?
You may want to at least investigate the 4-stroke bracket made by Bombardier Johnson/Evinrude.

Steve,
I think what MPQ means and what I am talking about is not the outside mounting bracket, that you put the engin on (I almost said Motor, or is that right). I mean inside the boat where the bolts come through the transom. My bolts are just backed by four large washers. It looks like it would be better served with a larger backing plate here.
Is this how it is on your boat or do you just have the four washers too?

Thanks Matt, in that case it would depend on the motor head dimensions and degree of tilt so it clears the deck and/or rear stanchion.
LOL, (duh!) I just read your post again Matt and yes I think it would be especailly advisable to use an "inside backing plate" with a 90 lb motor.
Sorry guys, too much sun over the weekend.

Don't want to sound like I'm from the Department of Redundancy Department, but if you're going to stick anything bigger than a 6HP engine on the back, you'd better reinforce the inside of the transom - good thinking that you caught that one before it busted off.

By the way, I also just replaced my (rotten) plywood mounting bracket with the CD issue (1/2 metal, half poly) - with the help of a drill, most of the pre-drilled holes (3) will line up ok and will support the additional weight - the Garhauer (black plastic, rated 15HP) mounting plate didn't line up with the Catalina bracket at all - too wide. ;)

There's always something!

I have a 1980 C25FK with a 9.9 Johnson Sailmaster mounted like you indicate. I have never had any cracking or problems of any kind. Now that you have brought up the issue, I may go ahead and be safe and back up with some exterior grade plywood.

I went one step further with my new bracket for a 108 lb. extra-long shaft high-thrust 4-stroke... I put a 1/2" Starboard (plastic) board on the outside as well as the inside of the transom, under the bracket mounts, to spread the stress. It extends well below the bracket mounts, so that the pressure from the deep prop is distributed to more of the transom. I had noticed some deforming of the fiberglass from the edges of the old bracket, so decided to give the fiberglass some relief.

I had to get some 4" bolts to go through the additional inch of material.
