Honestly, no. Because of where the thru-hull and manifold ended up, I would have to pull the seat box and floor up to get to it..........boat would sink long before
During this off season, I am reconfiguring the intake in order to solve this dilemma. I'm honestly not worried about a leak sinking the boat. With all the fitting below the water line 5200'd and all hoses double clamped, the odds of a failure are slim to none but the piece of mind of having a cut-off is nice.
