Being the crazy kid i am i did not test the boating waters with a small boat but jumped in with this 37 footer twin 8.1' s. The boat itself was a 'GOOD" deal..it was a bank repo but the down side is no real support. The boat is stripped of owners manuals, shore power cords, stereo face plates etc. I printed a owners manual from Four Wins but think that the lack of info is staggering. First question: The dock i have it at has a single 30 amp outlet...mu Four Winns has 2 30 amp outlets...do i need to buy a y cord for 30 amps to run it or will i blow breakers left and right ? Will i not be able to run A/c if i only plug into 1 boat plug in ? Trying to figure out what cords to buy. Next question is the water in the boat has antifreeze added to it. How do i discharge the water ? How do i flush it ? It appears that it non toxic rv type antifreeze. I am open and appreciative of any help at all.
