When I first bought my C-22 last winter there was no bilge pump.I bought a 500 gph and after using it got to thinking that it wasn't very impressive.I then bought and installed a 800 gph and installed it along side.They are on seprate circuits and swtiches.What would be a safe minimum?Also there is a boat supply store that sells parts very reasonbly,I would like to replace all the fuses with circuit breakers. Is there recommended? I'm thinking that I have never have to worry about not having the proper fuse at the worst possible time.
