This is a custom fabricated outboard mount that will bolt to the swim platform of a larger boat. It was built from marine-grade stainless steel to handle virtually any size/weight of outboard motor. There is no production outboard motor mount on the market anywhere near the strength, size/weight/stress handling of this custom built mount. It was built to order by a custom fab shop at a cost of more than $800. Price is $300, FIRM, CASH.
