I've done it many many times on a 24, just wondering what it is like on a 25. I need to mount a bilge pump.

Where are you going to mount the pump?

The old Attwood v900 plastic mount broke. I was able to find a replacement on ebay, so I'm going to mount it in the same location under the engine. It will be a lot easier to get to it with the seat out. I also have to mount a transducer and clean up the old glue/resin from the previous owner. While I'm at it, I might as well replace the impeller. I think I could tackle all those jobs and maybe a few others with the seat out to make my life easier. I just got the boat.

The back rest is held on my lag bolts to the fiberglass base the base is held down by visible screws around the bottom, the hard part is the center arm rest things. You have to take the circle covers off from inside the bench and reach your arm up and take the nuts and washers off from inside the wall on both sides. Unhook the battery switch and it should be out. Any questions let me know done it to many times.
