People have told me this Tommy to just weld them on but think it will be better if I make them adjustable, there's just way more room for adjustment, the bend it down method well I bend usually to much. When I build this 70/130hp motor i probably won't need the trim tabs.... really been thinking of building a boat with a pad rather then add a pad to this one which I think is to long anyways. A boat maybe 13'7 or 14'7 something like that would be good for this motor and want it skinnier. I need to try and find a program i can buy and take my ideas and put them into a program and see if they will work or just go for it.
By the way Tommy the original set is to dam short they measure like 8"Lx2"W while these adjustable ones will be the entire length of the back of the transom. In theory I'm hoping more surface area the water is running over the tabs and i don't need to bend them down so much and get the same affect and gain more speed. This is what a lot of drag boat racers have I have seen. If it don't work cutting them off and back to drinking some Sake and putting my thinking cap back on LOL
