Author Topic:   Adapting CMC Power Trim to 1965 Evinrude

Hello Folks. I am considering a CMC power tilt and trim for a 1965 40 hp Evinrude that has screws and clamps--and original paint on prop. This is for my 1963 Boston Whaler 13-fotoer. With the unit at $520 and adapter at $60, I might find another motor with tilt and trim, however, the Evinrude is in super shape and fits the era. I do hate to put holes in a Boston Whaler hull even if sealed, however, my back would sure like a power tilt. [Readers who can impart] knowledge of CMC are much appreciated. Good boating, Bill

I have (my brother has it now) 1962 whaler purchased brand new. Till this day we have not drilled holes in the transom to hold the engine on. We have used the clamps that are on the engine. We have had engines from 18hp to 40hp on the whaler and all of them have been clamped on. Just check the clamps each time you go out for tightness...good luck

I do not see a small boat electrical problem associated with drilling holes in the transom. Is there something we could help you with regarding the electrical system on your small boat?

Sorry jimh, I thought I was in the repairs/mods section. Maybe I wasn't clear on the tilt/trim unit from CMC. I was hoping for input from readers on any experience with the power trim/tilt by CMC. Thanks.

I put a CMC on my 13ft Boston Whaler with a 40hp Johnson... it worked VERY well. I had the CMC in my 13ft for about a year, and got rid of it when I switched to a Honda four stroke.

The weight is a bit much, combined with a 40 horse Johnson, and is comparable to a modern four stroke in weight.

My 13ft is a 1975. My Johnson 40hp was an 88.

You can see a picture of my setup in the water here:

I like my Honda 40 better than my Johnson with the CMC. The Honda is much quieter and better behaved. The Johnson was nosier and smellier - but MUCH faster once mounted on the CMC.

One major benefit of the CMC was how far out of the water it kept the lower unit of the motor, as seen in the photo.

I did have a problem with the auto reset circuit breaker that came with the CMC. It lasted all of a couple months under the cowling of the Johnson, and then I started having problems tilting the motor. It simply rotted to pieces in a salt water environment. I replaced the circuit breaker with a fuse and never had another problem.

All that aside, don't you have a cut out on the transom? If you add the 40 pounds of the CMC, will you have a problem with water coming in over the transom? You may want to solicit information from others with the cutout.

Have fun,

Russ

Again, I do not see any relationship to Small Boat Electrical topics in this discussion, and I am closing the thread to further comments. Please resume this discussion in REPAIRS/MODS. Thank you.
