lets see how good you guys are out there. Could you tell me what used to be bolted on the back of this boat just by the size and shape of the hole and the amount of bolts??? i just picked this up with no motor and no outdrive for 200 bucks. I'm assuming its probably a jet drive of some sort. I'm new to boats. the front motor mounts are hydraulic and can raise up about 3 or 4 inches. what is that used for trim of some sort? any help would be very much appreciated. THANKS!!
