I'm reviving a 1980 PowerSlot, have a leak on the driver's side of the main stringers, not sure if it's exhaust but wanted to ask you to clarify if you could have removed the exhaust out the back of the boat or if you/we do in fact need to pull up the floor? My dealer said the muffler will pull out the back of the boat along with the 4" hose that goes to the exhaust manifold, the connection between the two is under the floor. I'm trying to avoid ripping up the floor to check the exhaust system for leaks. I might pull the gas tank out and try to reach around the floor board to feel for a leak. My PO replaced the stringers so there isn't another (bigger) reason to rip up the floors.
