My Zodiac Pro 420 leaks too
I just got brand new tubes from Zodiac and installed on the 1987 hull. I took it out for the first time to see how she runs. We could see some water coming in from under the tubes when we were under way and also at the stern where the tubes hit the hull. I also have about 3 inches of non-used space in the running slot that the new tubes do not utilize. Guess I'll fill those portions in with Silkaflex or 3m 4200.
Also, I found areas in the bolt rope slot where the hull is pulling away from itself. Does anyone have a good way to fix this? 3M 4200 or 5200 as a temorary remedy? Glass it and sand it? Duct tape? It needs to be thin as any thickness will limit the installation of the tubes bolt rope slip on application.
And next is playing with the fuel pump......
