CMC Transom Wedges - 2 Degree

Great Results

Have a 1977 Robalo center console that is very butt heavy so the bow rides high with trim fully down and couldn't control bow in a chop the way it should. I doubled up the wedges for 4 degrees of additional down trim. It has completely resolved the problem. Single plate 2 degrees would have probably been good enough but I like having just a little more if needed so the double plate was the right choice. Great Product

Wedge effect on my boat

I bought a “performance” aluminum hull to access waters mainly for hunting and fishing. What I soon learned is that often you can’t just put an outboard on these boats and get a good ride. Even with an adjustable jackplate, tilt and trim, and having a prop shop add “cup”, my boat porpoised (at full throttle) when I had a passenger. I found out several people used wedges to give additional “negative” trim, slightly changing the motor angle, an enhancing performance. In the context of setting up a boat and motor, the cost of wedges is minor so I thought I’d give the 2 degree a try. I chose the CMC 2 degree wedges because they are machined from an aluminum billot, fit standard outboard bolt pattern, and can be used for additional negative or positive trim angle (installed thick part up or down). Another big consideration was that the CMC wedge design (length) did not extend beyond the length of my jackplate. I’m pleased to say after installation I can trim (at wide open throttle) for a smooth ride, with or without an additional person on board. I didn’t lose or gain speed, had no negative effect on hole-shot, but it was enough adjustment to enhance performance. Well worth the price and easy to install (if you have a hoist).

boat porpoise issue

put the 2 degree plates in between boat transom and motor transom gave me enough angle to eliminate porpoising... Easy Mounting, nice product!
