    5.0 cuts out

    Still trying to figure this out. Seas have to be radical enough to make this happen. Motor doesn't completely shut down, but will misfire, when the boat gets vertical. Have eliminated sucking air as a possibility. Can water in exhaust run back to the engine? Water separator isn't picking up...

    ocassional stumble

    Posted this problem before. On any smooth or moderate day, my 2000 5.0 efi runs perfect. 245 sea ray. Bucking 3 to 4 footers with high winds at about 3200 rpms, it will stutter and drop down. Never dies, and runs smooth at a lesser rpm. Turn this boat around, never a problem in following seas...

    water in fuel

    Doesn't look easy, but does anyone have a technique to get the water out of a 70 gallon fuel tank in a 2000 sea ray. Pickup is at the top. Not sure what it looks like inside of the tank. Could I suck it dry from there? The sending unit is in the center, and not easy to get at, because of the...

    Big time rumble hard left and hard right. Pulled the drive. U joints are tight and smooth. Gimbal was well greased and turned smoothly.
