Dyna craft bait boat leak at impella - Boating

Hello, I have a Dyna Craft Bait Boat MKII some time it made the following problem, during operation sometimes stops working, and after a while starts to work again. I have heard the same problem with the same boat, whether it is manufacturing defect and can anything be done to remedy. I think it is something related to the scope of the boat, but good to hear your opinion. Thanks

Take the cover screws out (4 screws) also the screws holding the pipe that goes to the outlet nozzle.You should now be able to remove the cover.underneath is a rubber gasket,replace or reseal
