You need to pull up the floor board section to which the motorbox is mounted (at the hinges), and put some sort of reinforcing material beneath the screw attachment points. That honeycomb aluminum stuff was no match for the force of the screws and tiny washers used from the factory. I used a small strip of treated plywood and some large washers and it worked great. You may need some longer screws.
If I recall correctly, your boat has two removable floor pieces, and the hinges are attached to a very small piece. You might just want to replace the entire piece with something more durable and waterproof.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
