There was an individual who repaired aluminum
outboard tanks, including the Waterwitch tanks,
but he got burned out. He told me- “I want to
work on my own stuff”. He was really good at it
but its not a fun job. I’m not aware of anyone
else that is doing tanks for others.
Tubs.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
