Author Topic:   CMC Set Back Plates

A recent thread on this topic got me thinking about asking the manufacturer about making a special order for these set back brackets:

"The two piece adjustable manual has 5" of slot adjustment at the motor mounting bracket and 1-1/2" of adjustment at the transom bracket. After height adjustment has been made, tighten the four bolts on the sides to 100 foot pounds to hold the position in place. Available in 5-1/2 or 4 inch set-back."

The brackets' transom mount comes with upper mounting holes, and the standard B.I.A. slotted lower mounting holes. Owners of classic 17-foot hulls that currently have their engines mounted using the "blind holes," have to drill their own blind holes in the transom side of the bracket.

CMC is willing to do a special order, where they place the transom brackets' lower slotted holes to line up with the standard B.I.A. transom blind holes.

Thus, full adjust, with no holes or other modification needed. I'm ordering just the transom brackets, since I already bought the entire set up, but they indicated that they could make more. The price is the same as the original. Orders would be placed directly with CMC, and paid to them. If anyone else is interested, let me know and I'll give you the details on how to order them.

P.S. I'm not getting anything from this, just thought I'd pass on the information. They are running a new batch of these in a few weeks, so if you want the modified version, you will need to let them know soon.

Rob,

I have a friend that is probably interested.
Can you give me a Ball Park figure as he is Cheap... I will pass it on to him.

Joe, I think they charge $157.00, direct from CMC.

Thanks Rob.

I have since found the pricing and you were right on.

And here is there page on Set Back Plates:

I will let my buddy know as the $157 should fit into his budget.

Is there anything special we need to tell CMC about this bracket that already has the holes drilled for the blind holes?

Thanks,
Joe

Sorry to get you guys excited too soon. I just got another call back from CMC customer support. Apparently my special order went to the shop, but the machinist said that to reprogram the computer to cut different holes was too costly, and they can't do it. Sorry about that, back to the drawing board I guess...

Rob, wouldnt it be cheaper to just have a local shop modify your existing bracket? Do some of the existing holes line up only partially? Is there a concern that additional holes would reduce the integrity of the plate enough to be dangerous?

I have been thinking of putting one of the manual plates on the side of the transome to use for a kicker, they are stronger than a kicker bracket, and would be about the same as mounting a kicker directly on the transom If I didn't have a late model with the rub rail that wraps around the corner.

Mike, the only problem is that when the brackets are mounted to the transom in the highest setting (ie the lowest upper bracket holes) the blind hole mounts are too close to the brackets lower sliding holes. The solution is to use the mid-range upper mounting holes, in order to allow sufficient space to drill the blind holes farther away from the lower sliding holes. This means the bracket's sliding adjustment is maxed out, and the only way to raise the engine even higher is to use the motor mount adjustments. I'd rather raise the brackets on the transom than at the engine mounts, as the higher I raise the bracket's sliding adjustment and engine mounts, the more leverage the engine puts on the transom when it powers up. Plus it is a pain to drill the holes ;-)

The brackets may work fine for a kicker, I'd only worry about the kicker's tilt clearance. If you are drilling new holes for the bracket, then blind hole mounting is not a problem...but remember, measure twice and drill once!
