Re: alphaone/gen 2 - exhaust flap?
Yes... it prevents you from having to replace the engine... ask me how I know that
You need to fix it.
Just posted the following in another thread:
"Regarding the flappers... you should have a rubber exhaust hose that comes off your risers/manifolds and attaches a steel Y shaped exhaust tube that allows the exhaust to leave the boat through the drives. Where the exhaust hose connects to the Y, the flappers are ususally right there. You will likely have to take the riser off as just removing the exhaust hose will not give you enough access... but you can try. Use a large flat bladed screw driver to gently run the tip around the exhaust hose where it slips over the Y tube to break it free after you remove the clamps.
Your flappers should be "closed"... meaning they are gently resting against the side of exhaust tube. They work by letting exhaust and cooling water to push them open to escape but prevent backflow from the outside water coming back up the exhaust from outside the boat and flooding your engine."
