    Mercruiser coil output

    How long have you had the boat? Folks replace perfectly good coils every year. Being a 1980 I'm going to assume it has points unless you advise it has been changed. The 9.5 to 10.5 volts at the coil is within limits with key turned ON. You should get a full 12V only when the engine is being...

    Bravo 1 Corrosion or Something Else?

    Went out to my shop and had a look at my two spare drives. They both have a hole in this area, and this is the channel which supplies water up thru the drive. The issue with yours it looks like the hole casting was not cleaned out. This should be a square sort of hole. The way yours looks...

    I'm wondering if the outside of the cable is loose from the brass tube and nut? Also is the nut tight

    Bravo drive won't go forward, was fine when I shut it off??

    The puzzler is the drive shifts when the drive is off but not when on. The cable is attached to the bell housing, check that the cable jacket is tight and does not have any play, so it is not able to slide in or out. When I said clutch previously I'm actually was thinking shifter assembly...

    '74 merc outdrive won't go into any gear

    That should be the reverse lock valve. Don't know what motor you have but do think the adjustments should be the same. Maybe achris can fill in the blanks, but here is some from manual 2

    Mercury trim & tilt is jammed and only goes down halfway. Video included.

    Howdy There is a shinny stiff wire under the motor that gets flipped up or down, then the drive gets dropped down. If it stays up its used to help hold the motor up. That wire is appears to still in the up position. Raise the motor and flip it down/up and then lower the drive

    Base Timing using electronic tools

    Being a 2002 I'm going to bet you have a distributer cap that looks like this If you do then you cannot adjust the timing with a timing light. It is done by positioning the distributer in the correct location, and only very slight adjustments can be done

    Trim help..89 Celebrity Mercruiser 3.0

    The drive should not be trimmed up more then the trim limit position with the motor running. If your using the trailer switch the drive can be brought up past the limit. While running at low speed or high I don't see you going above this limit because the boat will be porpoising and/or the nose...

    5.0 gl-a starter ignition problems

    Howdy Get a voltmeter and start checking fuses and cables for 12V. When you turn the key to ON do the gauges turn on? Check for 12V on the start relay (item 17) on the small yellow/red wire Check that your 50 amp breaker has not tripped

    Mercruiser 4.3 TKS won't idle

    Yes attach the hose to the ear muffs and cover all the holes on each side of the lower section of the drive. Turn water on full, and don't rev the motor over 1500 rpms. Just let it idle will be more then enough

    Any Carburetor Tuning Tips for a first timer?

    Your plugs look more carbon fouled, so a bit to much fuel, weak ignition system/timing, gap and/or incorrect heat range on the plugs

    1988 Marlin 4.3 alpha 1

    Ran into this issue twice this week, and it would be installed this way IF the filter stone was used. Before all the small paper filters and screens with a plastic body, we all used those stone filters. They have all gone by the way side these days

    87 OMC Cobra 4.3 engine wiring issues

    Howdy May not be a marine ALT, if that is the case then NO it should not be on the boat. The auto ALTs are not ignition protected. OMC used a 3 wire ALT like Merc, see drawing I would get a internal resistor coil and run a new non-restive wire to feed it The hour meter can be connected...

    Putting down out drive in winter and solenoid failure?

    If the trim limit on the drive is not working this will keep the trim switch from working in the up direction. As before check the continuity with the three prong plug

    5.7 LX EFI random idling stall - electric fuel pump?

    The VST pump should be running so long as the motor is running. Any pressure on the fuel line to the injectors which exceeds the regulator setting is released back to the tank. The tank is just like a carb bowl, and the low pressure pump keeps the pressure there until the float drops and...
