The Porta Hydraulic Transom Bracket is a travelling parallelogram that combines the best features of two products, the transom and the jackplate. We have two gently used TWIN engine brackets. 21"setback 15"liftt 46"Long. They are the f-series and can hold up to 800 horsepower. Only thing it needs are the hydroponic pumps and they are relatively inexpensive compared to the whole unit. 2500$ a piece or 4,500$ for both.
