View Full Version : 1998 Prostar190 - I need a back seat

07-08-2014, 08:20 AM
Purchased my PS190 without a back seat years ago. It's was used as a demo boat for watersking. I am now wanting to build a rear seat similar to the factory specs. So it can be used for a rear sundeck as it was intented. Does anyone have build info, advice, and dimensions? http://img.tapatalk.com/d/14/07/08/u5a8ajuq.jpghttp://img.tapatalk.com/d/14/07/08/9amabaja.jpg

Here was my re-build

I just re-did mine as the aluminum honeycomb was trashed in one corner. I used 3/4" marine grade plywood, and coated it with polyester resin. I also screwed a piece of angle iron under the seat for additional support. It is more sturdy than the original, but weighs twice as much. If I had it to do again, I may not use marine grade plywood because you make about 5 of them with treated plywood for the same price. Here is a print I drew up from measurements of the original honeycomb seat:

Also, here is a link to my thread, though I didn't do a very good job actually documenting anything.
