The Mega Jackplate is a meticulously enginered and robustly built electric jackplate system designed for today's large, heavy, and powerful outboard motors. Allowing boaters to maximize the output of their engines while offering more flexibility in shallow water, it is offered in 6", 8", and 10" setbacks. There are 2 versions available: a standard bolt pattern designed to fit engines like Yamaho XTO, and a wide bolt pattern designed to fit Merc 500/600.
