    Trim pump not working in down position

    The drive was up all winter, I do usually run it up until the pump loads. I will check later this afternoon to see what type of pump I have. I will post a picture.

    Trim pump not working in down position

    I have a 1989 Alpha one mercruser stern drive and just this weekend the trim pump has stopped working in the down position. Unit comes up just fine but no downward movement. When trying to get the unit to go down, the pump sounds different than it does in the up cycle. The unit worked fine last...

    Transom repair

    I have a 1998 25' invader with 350 GM stearn drive, I believe my transom may be rotten. Do larger boats such as this have wood sandwiched inbetween the fiberglass like smaller outboards do? If so how do I go about getting to the rotted area. I know that the motor and drive unit have to be...

    Stern Drive transom lower right bolt fell out

    wow!! pulling the engine was not something I had even considered. I have had this boat for two years and all I have done is throw money at it. Seemed like a reasonable deal for the year boat. The engine was just out before I bought it.

    Stern Drive transom lower right bolt fell out

    Is there a way to reinstall this bolt? It would come thru the transom down in the bowels behind the motor so I dont even know if I could see where it goes. Anyone else have this issue. This is on a 1989 mercruser outdrive.

    89 Mercury outboard 100 hp shift shaft alignment

    I replaced the water pump in the lower unit and now I have nothing at the prop. I tried the method listed on another page of turning the lower shaft all the way CCW until it clicks and this should have been neutral. But I still have no drive at the prop.I have changed several water pumps and...

    1989 Mercury outboard lower unit rebuild

    I am getting ready to replace the seals and gaskets on my 100 hp 4 cylinder outboard lower unit. What seals should I suspect is leaking water into the gear case? I will replace the water pump while I have the unit apart. I have done the water pump 4 times in the past, but I wonder if I should...

    Mechanical fuel pump gph question

    Yes the motor has run higher than 3500 in past, the motor was rebuilt 3 years ago with maybe 50 hrs on it. I doubt its tired yet. I drilled a few small holes in the transom to check for rot or water. I got wood shavings out of the holes with no sign of rotten wood.

    1989 25' Invader cabin crusier fiberglass stress cracks

    Would it be normal to see stress cracks in the gel coat of a 1989 Invader cabin cruser? The cracking is in a radial pattern around the stern drive on the transom.

    Missing transom bolt on Mercruser outdrive to bellhousing.

    Do you know what size bolt it is and thread pitch? Once thru the transom what does it thread into? The bell housing?

    Missing transom bolt on Mercruser outdrive to bellhousing.

    I see your point, its a money thing. I would never complain about hardware being replaced during a rebuild, especially when the failure results in a sinking boat. The outdrive was rebuilt at the same time.
