I just bought a 97 sunsport that I have some questions about.

To access the drive shaft how do I remove the floor plate in the rear. It seems like the engine cover has to be removed and then looks like the plate slides out but is there any screws or latches holding it in place because it seems like it does not want to budge. It also seems like the rear seats are resting on the plate holding it in place making it more difficult to get out. I would like to replace the packing as it leaks too much for my comfort level.

In the ski locker to the stern of the boat there is carpet and upon lifting up the carpet there is a round disc plate in the middle floor exactly like the bilge plate by the ski pylon that has a small black circular thing in it with two wire connecting it. Does anyone know what this is?

Also in the same locker if you are standing on the swim platform facing the bow of the boat on the right wall nears the top there is a circular hole that has a white plastic insert with a hole in it that I can not figure out what it goes to?

It also has on the stern port side of the engine 2 white dials one with red dots and the other with blue dots screwed into the plastic cover plate of the pro boss gt40.
One hose is grey in the middle and the blue dial has a blue hose and the red dial has a red house....It looks like its a onboard shower and I am wondering if the rear bilge plate holds the pump and maybe the hole in the ski locker is where the hose comes out of.

I will get some photos to help explain but did not know if this was factory or add on. Obviously skiers choice had little information.

If anyone has any manuals/diagrams/brochures for this boat it would be much appreciated

Thanks
