Holding tank or Type 1 MSD for Cal 39
I have a 1983 Cal 39 with a 9-gallon holding tank mounted under the V-Berth. The tank is too small, the hose runs too long, and the whole unit smells bad. There is a manual pump for overboard discharge, which probably causes some of the smell. I need to overhaul the whole system.
Does anyone have experience with the Electro-Scan Type 1 MSD? How does it compare with a holding tank? I am considering replacing the existing tank with a 25-gallon tank made to fit the space under the V-Berth, and replacing the manual pump with a macerator.
