    5.0 efi jets not spraying

    Howdy Sure do like the serial numbers, the only issue is the numbers you gave are for 1998 and up Alpha 1 Gen II outdrives. Could sure use the motor serial numbers or at least the year and which size. There are very few real simple things to fix this kind of thing, but start by removing the...

    ignition wiring

    There is a start relay (some call slave relay) on top the motor. When the key is turned to start it energizes a relay on the motor which sends power to the starter solenoid. Its probably going to look like one of these, or a square plastic cube

    The Gray wire is the 5V reference voltage, and at idle it should read between 1 and 2V on the Lt Green wire

    Westerbeke instrument panel getting hot

    I'm thinking with the amp meter pegged, its the amp meter that is shorting out. Either that or the battery is. This is from the manual

    Bog @ 3400 rpm

    The main carb jets and valves. As the carb opens the air passing causes fuel to be drawn out of the bowl. As the throttle opens the needle valves are lifted out of the main metering jets.

    shift cable head scratcher

    Your shift cable should be routed as in the pic below on the left As for it not shifting correctly I would go to the Adults only section, Mercruiser, then look at Chris's vid on adjusting the cable. As for the switch, I would need to see what your looking at

    Prop hub slip? '95 Maxum 4.3 L Mercruiser Alpha 1 Gen 2

    Suggest pulling the drive and check the coupler. If the drive is out of alignment for long enough the drive shaft will eat up the inner coupling. Given enough time it will eat away all the teeth and start slipping. If this happens you will not smell any rubber burning. Note in pic below this...

    Bravo 3 run up with water supply direct to impeller

    My opinion is using a barrel on a Alpha drive for a short time is doable, but not a Bravo. The Bravo needs the water level even with the drive shaft until it starts being able to draw the water in, a barrel would not be high enough. I attached a 5/8 ID garden hose to my spare B3 drive on a...

    2007 Tahoe Q6 merc 5.0 305 MPI motor won't start after running it

    The rules out the fuel pump, that is when it won't start. All this info we need when it won't start. You have the HVS distributer and many have trouble with the cap but don't see that as the issue now. When you crank over the motor does the tachometer move up around 200 rpm or more? The...

    SOS... Guardian issue

    I do believe your pressure should be above 32 psi and should be in the 43 range. Cannot say with 100 percent certainty because I don't have a manual for your motor, only 31 which is for 2001 and a bit higher. Just for stinkers and giggles, go to the shift plate and find the gear switch. This...

    Engine running rough

    To power an electric pump it needs to have an oil pressure switch inline so if the motor looses oil pressure it will turn OFF the pump. You also need a bypss wire so when the motor is being started the pump gets power to supply fuel to the carb. Something like this A factory install is like...

    7.4 mpi fuel issues?

    Using a 45 gallon tub is not the best way to run the motor, even if it covers the intake holes. Manual shows 43 psi while running, dropping down to 38 isn't bad but would like to see it a tad higher. With it idling remove the vacuum line going to the regulator and the pressure should increase...

    Mercruiser MPI fault 54 and 56

    The seawater pump low is code 23 The sensor is located on the power steering cooler and in most cases its mounted across the top of the rear of the motor. I have the drawing for the sensor and it looks like 24 MM but not sure because its fuzzy. This is what I have for the different ones in the...
