    Choke valve position cold engine

    it may have been flooded or overly rich. Opening the choke and throttle will help clear a flooded or rich condition. when operating properly the choke will go fully closed but pops open a bit when the engine starts, then slowly opens more to full open when the engine warms up. Get it running...

    No water coming out of the exhaust on muffs

    Exactly -only time I had an issue with the no choke was when I took the boat out in mid october (upstate NY) cold wet and rainy weekend in the 50's. a few min of warm up at fast idle was good to go.

    No water coming out of the exhaust on muffs

    either of them the element can be turned to force it open. When I had the element on my old boat just twisted the element such that it never came on. Ran it like that for many years, don't really need it much in warmer weather anyways.

    No water coming out of the exhaust on muffs

    No the opposite, if choke was closed the whole time it would explain why plugs are black and soot covered. When doing a cold start stabbing the throttle a couple times does two things. Sets the choke as when cold the choke will close , second the accelerator pump will push some fuel into the...

    No water coming out of the exhaust on muffs

    Depends on if it was loose enough that choke wouldn’t open. If choke stayed closed would expect it eventually would foul the plugs and not run Watch what the choke is doing when u get it running

    07 mercruiser 4.3 no start

    Use a VM to test Key switch could be the issue- so are you getting 12 v out of the key switch in run? If no probably the switch. if yes, then where are you loosing it from switch to coil? On a lot of boats the 12v come from key switch and daisy chains through the gauges, and probably a fuse...

    Only 3 Drain Locations?

    that may be depending on what cooling system you have I think you could have as many as 7 or as few as 1 (single point drain). issue is to make maintenance "easier" they hose over what were separate drain locations to a central or a fewer number of drain points. while in theory this is great...

    replace Mercruiser 2.5L 1989 with Mercruiser 3.0 1994

    I am assuming your old boat does not have power steering and the new engine does? the 8-10" long metal tube in the water intake hose is a powers teering cooler, this cools the PS fluid on the return line. Leave the cooler in the water inlet hose, remove the PS pump and 1/2" or so diameter hoses...

    Help me set up my new edelbrock 1409

    The over flow fuel line on the intake helps the fire start faster, so you don’t waste time just getting a whiff of smoke… the marine edlebrocks have a gold irrodite or similar finish vs the bare aluminum that the street carbs have. The bare aluminum corrodes in a car sitting in a garage … the...

    Rebuild my choke to Electric. What with the "holes"

    Yes and we know you have enough pictures already to start your quadrajet only fans site… if you know the principles of how it should work you don’t need a manual and can figure it out.

    No what do lugs on cap look like? Mine tend to get green oxidation after a few years.

    Over heat alarm

    There are three switches on engine which can make alarm sound - high engine temp, low oil pressure, and low drive lube bottle . All three of these switches make the ground connection to the block for the buzzer. Thsee are completely separate from oil pressure and temp senders that work the...

    1990 mercruiser 4.3 no spark

    Turn distributor while cranking. If backfiring yes timing is wrong reading this wonder if you had a grounding issue on distributor to block . Not sure if third wire off sensor is a ground which would nix my theory… but if clamp is loose …

    What prop are you running. I had zero issues with aluminum annodes in fresh when I ran aluminum props. went to a big 4 blade revolution 4 and had some pitting like u mention. This is lift kept not in a marina not connected to shore power. also found better results with oem merc magnesium vs the...

    07 mercruiser 4.3 no start

    Cycle the man overboard switch if it dies when you put key to run it’s loosing ignition this way. found that out the hard way … when starter is running ignition is powered via starter I think, when you turn key to run if man overboard is tripped there is no longer 12 v going to positive side of...

    Rebuild my choke to Electric. What with the "holes"

    that is it if you click on the pic of this intake manifold off a 165 (just swagging the engine has to be a 3.0 or 165 st 6 by pic) you will see the tube you mention https://www.marineengine.com/newparts/part_details.php?pnum=MER58759A13 if you can find a welch plug like used in carbs that...

    Rebuild my choke to Electric. What with the "holes"

    whats the serial number on the engine you are working on? this will help see in parts diagrams what should be there Usually the hot air style chokes had a tube inside to heat the air to the choke from the exhaust gases. On an old V8 this would be in the exhaust crossover in the intake. The...

    07 mercruiser 4.3 no start

    Loose battery cables or dead battery. Man overboard switch ? Heavy throttle - is the float bowl overflowing flooding the engine ? opening throttle wide is the way to clear a flooded engine.
