On a Prostar 196 or 197 I found a way to get the dog house and rear floor panel out of the way with no assistance, but its not on the ground. Only takes one frail old skier about 5 minutes.
I just replaced the damper plate and relined the doghouse with foil insulation with no assistance.
Before you start, cover the rear upholstered deck with a moving pad or a couple of beach towels so the vinyl engine cover and the vinyl deck are not directly dragging on each other with the weight of the dog house.
1. Remove the screws if any that hold down the floor panel
2. Remove the 2 pressure arms that support the dog house when you have opened it.
3. With motor cover opened, straddle the transmission with your feet on the carpeted floor facing the back of the boat.
Reach down and grab the leading edge of the floor panel and lift it. If you keep pressure towards the back of the boat as you lift, the doghouse well end up -upside down- on top of the upholstered rear deck. Stuff a folded towel or another spacer between the dog house and back of the rear deck because it feels like it wants to roll backward. ( you may need to pry the floor loose the first time with a 30" piece of 2x4 under the leading edge of the floor section )
When your done, just reverse the process.
Probably won't work on other boats with a different rear deck configuration.
