Hey guys i was on this forum two years ago when i had my first boat 2452 Bayliner, Now I need some help!!! Two Days ago I decided to buy a yacht that needs work. I bought a 1992 Carver 33 aft cabin. The problems that it has with it is the battery compartment got water in it after the snow storm in 2010. The canvas in the back broke fell and blocked the drain. the water started to come in through the door and got on the battery and shortened all 3 of them and the bilge pumps stopped working so the water got on the bottom of the engines and on the bottom of the generator. After that they cut all the positive wires, rewired the bilge pumps to work directly from the spare battery. Them the boat was winterized and never was attempted to start. The Engines were rebuilt 3 month before the storm I got all receipts for maintenance with the boat. Yesterday I spend 3 hours and cleaned all the battery wires and got all my electricity to work on the boat through the battery's. Now I dont know what to do!!! Should I drain and change all my fluids, drain the gas, and unwinterize the boat and try to start it? or should I check something else? The boat has twin 7.4 Volvo's. I am not a mechanic just trying to save some money and do few things myself. Thank You Anton.
