Mechanical Installation Manual (750, 750 Quad)
2.2 Forces Applied to Hull
While underway, the Controllers transfer high forces at each of the mounting locations to the hull. Careful consideration should be given to the transom strength and condition to ensure it can hold the loads created by the Controllers.
For aluminum hulls, verify first the aluminum boat transom structure can withstand fast, repeated, and high forces created by the Seakeeper Ride Controllers during use before applying to the mounting surface.
Note: If an aluminum sheathing protects the transom structure of the vessel, then the load must be transferred from the sheathing to the transom structure on these installs.
