Re: kicker motor installation - pic of transom
It does not look like you have a lot of room on the transom.
Is your beam near 8 feet wide. Maybe it is just because of the size of your main motor.
If you get a bracket I would suggest you get one way over rated.
Like rated for a 20HP 4 stroke and Stainless for Salt water.
I had one with a lift of 15 inches and rated for 20 HP 2 stroke.
On it I had a 15 HP Johnson 2 stroke in the picture and it worked ok but a little hard to lift.
Later I added a second one of the same type then made mounting board to tie the two together.
I had to also tie the two release levers together also.
When complete it works very well. The second unit took all the side to side movement out.
Also made it easier to lift.
Now when I release the lever it will go about half way down then to get all the way down
must push on the top.
When all the way down and release the lever comes about half way up then have to lift from there.
I am not sure you have room for the bracket.
My brackets are about 1985 models and new one cost more but are better.
This year I converted mine to a 15 HP Honda 4 stroke and it works but could be stronger.
