I've got a 165 Navigator with a tiller steer 40hp. Mercury. Over the last few years, the screws that hold the seat base to the floor have stripped out. I'm about to pull the entire floor up (which means removing both rod lockers on the sides of the boat), unless somebody gives me a better idea. I removed the floor piece over the gas tank, thinking I might be able to reach under the adjacent floor panel to hold some nuts while I bolt the pedestal down, but alas, the gas tank is inside an aluminum well, so there is no way to reach through. Any thoughts?
