I installed an old-school battery isolator in the jetboat. I had it out today for the first time this year, first time with the house battery and isolator. Will be replacing the isolator with a Battery Doctor/Wirthco isolator later this week when it is delivered.
The isolator had ~13.6v coming in, but only ~12.4v going out to each battery. At that rate they'd never reach a full charge.
I'm thinking about scrapping the old-school isolator in the Sun Stream and replacing it with a Battery Doctor/Wirthco unit.

Not a huge deal for the MoHo since most of the time the house battery is charged by the power center with either shore power or gen, but with the old style isolator the starting battery isn't going to reach a full charge.
Anyone replaced their old style isolator with a newer, lower-loss isolator? Good/bad/otherwise?
