I have a 86 32' carver mariner and found a deal on a 5k generator in another 32' mariner like mine, I'm pretty mechanically inclined. What should I watch out for while installing a generator
What kind of generator are you installing? If it's in a Carver, I am going to assume it's a Kohler 5KW (or 5e, or 5cfz). Here is the installation manual for all three. Section 6 of the manual details actual installation. READ THE ENTIRE THING FIRST!! Make sure you pay special attention to the fuel delivery/filter section and the siphon break section. Pay extra attention to your thru-hull fittings!
Here is the service manual for the same. It details routine and emergency maintenance, including trouble shooting, wiring schematics, pluming information, hardware sizes, and expanded views of the unit.
