    1998 Volvo Penta 5.7GSi High Idling Issue

    I'm not a VP guy just trying to help until one of those guys come around. Not all but many times when the IAC is unplugged the idle will increase because some require a voltage to close the valve, otherwise its all open. If this is the case for your motor then I would suggest checking to see...

    Mercury 350 magnum problems please help

    Could be, but could also be the regulator is defective. You could test it without the motor running. Block off the return line coming from the fuel regulator going to the filter. Turn key ON and watch pressure. Turn it ON and OFF a couple times to see if pressure comes up. It should...

    mercruiser carb

    Either the internal passages are still clogged or the accelerator pump isn't working or adjusted correctly. If you can very slowly increase speed and get it going, then its the accelerator pump or circuit. If not much is working then it could be the carb, float, cleaning or adjustments. The...

    No power to ignition switch, other electrical still works

    You might have blown the 90amp fuse on top the starter. In any case your going to need a volt meter to see where voltage is not. Suggest starting with the 90amp fuse (item h)

    mercruiser carb

    Don't have a Merc carb view but plugs in a carb are used to close up manufacturing holes. The carb base is fist cast in a mold, then the casting has channels bored into it to pass fuel for the jets and accelerator pump. The channels cannot be bored any other way do to their size. With your...

    7.4 mpi no power

    The fuel pressure is a tad low (43) bit should run better if this was the only issue. I would suggest checking for codes. You can either have it scanned (easiest) or build one with a paper clip and an led with a built in resistor. Turn key to ON (do not start) and install clip and led. You...

    where do my trim sender wires go?

    You should have a Brown/White and solid Black wire near the rear of the motor. The Blk is ground and the Brn/Wht goes thru the engine 10 pin main connector plug. It makes no difference which wire goes to which wire on the harness. Here is how the transom goes together

    Lower unit oil reservoir on Alpha Gen 1

    It will work, this is the same setup Merc started to use before changing the transom plate to accommodate the lube bottle. Appears to just be missing the bracket to hold the line. There has been other threads of installing one, but I know of none which have come back with what they did

    Mercruiser 230 pumping water into bilge. Please help

    It looks to me to be the speedometer hole. Only issue is it might only leak when in gear going forward, it might not leak when just running.

    Mercarb question

    The pic below is for a Rochester but the workings are the same. The ball below the accelerator pump allows fuel to come in but not out. The one under the venturi does the same thing. Accelerator pump sucks fuel in when throttle is released to idle, the venturi one keeps air from being sucked...

    zinc anode in exhaust mannifold

    The manifolds are not as anodic then other metals on the motor. In short the aluminum drive will fail before the manifolds do to galvanic corrosion. In the table below note that cast iron on the left side come into being more anodic when placed to stainless. The aluminum is far more attracted...

    Mercruiser overheat

    OK that clears up the hose issue. There is a flow issue, so if the impeller is good we need to look at anything which can cause the restriction of flow. The gasket in your pic shows 4 long holes. The Mercruiser part number for the gasket should be 27-863724. This gasket has 2 large and 2...

    Mercruiser overheat

    With only 4 hoses then your motor should be a 1996 or newer and have a thermostat housing like this one If this is the case then you may have a restriction between the thermostat housing, hose, exhaust manifold and the riser. It might be the gasket between the two

    Mercruiser overheat

    In your first post you mentioned And English not being your first language I'm just trying to understand your issue before making a comment. Your boat is a 1996 but appears your motor s are 1995 or older. I make this assumption because of your pic. The pic shows the older style thermostat...

    1979 Mercruiser Manifold Conversion
