    1994 mercruiser 5.0 LX carbureted ran fine, barely fired, now no start

    Use an ohm meter between coil + and coil - and ypu should get a reading and again between coil + and coil tower, can’t say exactly what the reading is as I don’t know which coil you have but an open circuit reading meabs a bad coil, if you have a reading then it points towards ignition module or...

    1994 mercruiser 5.0 LX carbureted ran fine, barely fired, now no start

    Does the rev counter flicker when you crank, if not then check you have 12v on the purple wire on the coil + if yes then connect a test light between the coil - grey wire and crank, if the light flickers then the ignition module is working and there should be a spark from the coil king lead...

    Bypassing lift pump

    Did you bleed it at the injector? Slacken the nut on the pipe at the injector and crank until fuel leaks out, tighten and it should start.

    Volvo Penta Hydraulic tie-bar

    Sorry I don’t have the part number and it wouldn’tbe cheap as there are several hoses which connect to the hydraulic manifold on the transom between the engines. The procedure is to connect everything up with the hoses rising to lead the air up out of the system, you bleed by filling at the helm...

    Mercruiser 4.3 V6 rebuild fail.....so next step?

    The block is not divided so should fill equally from the water pump. Is the engine raw water cooled?, as the water passages between the block and head can get eaten away by rust which means the hole is too big and the copper ring in the head gasket which should crush and seal between head and...

    I have replaced several of these, its located under the top cover of the motor and is a small blue object attached to the motor top frame,. Its available as a spare part if you look on the spares list. You will have to split the plastic housing to get to the motor so try to obtain the sealing...

    Mystery OMC Outdrive

    You will always need to shim the gears when introducing new parts to an existing gear housing as there are variations in machining of the parts which is accommodated by different shim thickness. There will be a procedure in the manual as to how you do this step by step, the only parts I have...

    What Volvo Penta engine is this?

    These are originally Puegot engines, their weakness is the water jacket around the exhaust manifold. Its corrodes through and lets seawater run into the cylinders.

    Make sure its up to spec i.e. hardness of the metal, if it breaks it will trash the upper section of the drive.

    That is for cable operated systems, a DPH drive is totally hydraulic.

    Volvo penta autopilot

    A DPH drive only uses a small capacity pump as its not operating a cylinder but just opening the shuttle valve so that the servo pump pressure moves the steering rams. If its too high it will react violently and almost put the boat on its side doing an abrupt 90 degree turn as I found out after...

    Volvo D4.260 steering issue

    Helm pumps rarely give any trouble apart from leaks from the shaft seals, it sounds more like the shuttle valve is stiff from corrosion and not floating back to its neutral position. If its slightly off centre at rest it will admit high pressure from the servo pump to one side of the sytem. I...
