Hi,
I have a 1978 17 ft montauk where the battery is currently located at the stern.
I want to move the battery in the center console and am looking for the correct wire to run into the hull to do so. It needs to be waterproof. Is there a go to wire people recommend?
Thanks
Dave
I used tinned marine grade from Genuinedealz.com. They will make them to length with heat shrink and ring terminals you specify. Mine are 16' and (I think) #2 AWG. I can check that when the cover comes off. I used the largest diameter that would fit the rigging grommet on my 2020 Yamaha F90. 1988 17' Montauk
When Boston whaler started rigging Montauks at the factory with the battery inside the console, they did the following:
1. Mount two Blue Seas battery posts with 5/16" studs on the hull side wall near the navigation light terminal block. These come with protective terminal covers.
2. the original engine battery cables remain, and run to these posts. Cumbersome re-rigging of oversize cables into the engine is not done or necessary.
3. #2 AWG Ancor cable, one red, one black (or both black if you don't like the red look) is then run from these studs to the battery. These can safely be run in the boat tunnel. This effectively transfers full battery voltage from the console mounted battery back to the posts, where the engine cables then pick up the full current, just as if the battery itself was still in the stern.
