I have an 18' starcraft super sport rated for a 150hp motor, right now there is a 1976 johnson 135 on it with no power trim, I'm thinking about putting power trim on it next spring but i can't find a stock one for the life of me, so i was thinking of putting one of the CMC units on. Does anyone have any thoughts about this? Will me transom be able to handle the extra leverage from the motor being it will stick out 6"? Also the ones i have seen for sale are rated for 130hp and i have a 135, i have had someone tell me that it will still be fine but i am skeptical.
