hello and thanks in advance for your help, I have an 87 liberator with twin 350 alpha 1 gen 1 drives, last weekend i hit a log or something and the boat will go in gear forward and reverse, operates fine at slow speeds, but when i try to get it on plane the engines rev up and the boat wont get up, like its a slipping clutch, done really mess with the interals of them so not surewhat could be the problem. boat is still in water so i cant really see anything, taking it out this weekend. I did shut off the engines when i hit it didnt see any fluid in water as if a case cracked. the props didnt have any damage either.
