my exhaust blower quit working while on the water. When I got home I opened the hatch. When i turn on the blower switch a pump starts. this pump appears to have hydrolic lines and a reservoir.. my question what is this pump. it is on the port side

    Should be your trim pump.

    It shouldn't come on with the blower switch. Some wires must be crashed somewhere. If the oil is white it must have water in it. That's not good. Does that pump come on when you hit the trim button?

    Wredskinsfan32 erased his original post and marked this as "problem solved". I've reposted the original question for archival purposes just in case anyone else needs to find the answer to their questions.
