I know there are a few TMC members who also have houseboats, so I thought this might be relevant. I replaced the inverter on my houseboat and have the old one plus some parts available. Shipping is going to be a challenge if you're not local, the inverter is HEAVY (60 lbs.) and I don't have the original box.

** This is a marine rated inverter/charger (use shore power or generator). Please don't use a non-marine inverter on your boat; If you ever have an issue with the electrical system your insurance company will find YOU at fault for not using marine grade components and could deny your claim! **
This inverter has been tested and is guaranteed to work, it was removed from a houseboat when the power system was upgraded.
