I posted this on the "Head Mistress" board also but I thought I may get some more input here. I have a 91 H28. My 'head issue' has to do with some type of overflow coming out of the holding tank. The fluid is first visible under the engine and then if we are healed at about 15 degrees it overflows onto the cabin floor. This only happens as the the holding tank gets over half full, maybe even 3/4 full (no gauge, just an estimate). I 'sponged' up about a gallon from the floor and under the engine. On getting back to the harbor we immediately pumped the tank. Any thoughts on where this is coming from? I thought if the holding tank was full it would at least stay in the holding tank and maybe back up if we tried to flush more into it. Thanks in advance.
