Adjustable boat engine bracket (jack-plate)
VERSA JAC Bob's Machine Shop

"Made of high-quality, aircraft-grade aluminum, the patent pending Versajac™ has the same look as Bob's popular line of hydraulic jacks. It is rated for engines up to 300 hp and is available in 4", 6", 8", 10" and 12" setbacks as well as our mini jack plate line. Adjusting the jackplate for optimum results is easily done while the boat is in the water.

When it's time to upgrade from manual to all-hydraulic operation, converting the jack is simple. Using a few basic hand tools, remove the Versajac's manual screw assembly and swap it out for the new hydraulic cylinder kit. Then install the pump inside the boat. All BMS's hydraulic pumps are designed to mount inside for longevity and protection from the elements. Jack plates have "limited lifetime warranty" and pumps have a 3 year warranty (excluding water damage).
