Drivers seat ideas

[idruthrbfishin]

I run a 1648 modified vee with a 60/40 jet outboard. I have a center console, and I'm looking for ideas for a stand-up style drivers seat mount. I have an open floor plan, with 1/8" aluminum screwed down to the ribs. This will have to be a sturdy mount that will be taking a lot of abuse as I run rocky shallow rivers. Basically I am looking for a very sturdy way of mounting the seat to the floor/ribs. Screws will eventually work loose, and I can't really bolt it down to anything with thru-bolts. Any pics and or ideas would be appreciated.

Since the floor is screwed down you can unscrew it where the seat will mount and attach a piece of plywood under the aluminum floor. Then put the floor back down and mount a seat base / pedestal.

On our G3, the seat doubles as a livewell and is a two person seat, but not a standup. I don't remember the floor thickness, but it is certainly less than 1/8", and is screwed in place. With 1/8", I'd think that would be plenty strong for a screw attachment. Use some sealant on the screws to prevent back out.

Just thinking out loud. I'm envisioning a tubular framed seat structure with flanges that mount to the floor at four mounting points. Guessing 3.5-4" flanges. If you feel you need more support, go to a larger flange base. Say 6-8" diameter of 1/8". That would thru bolt to the existing flanges, and provide more screws around the perimeter with stronger support. You will need holes in the floor for the thru bolt clearance and a beveled edge on the new perimeter to minimize stubbing.
