    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...

    Here you go, A - 12V B - Ground C - Wake (ignition ON) N - Crank (Start) They also make a 10 to 14 pin connector so you can do it the old way :)

    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...

    Cracked Bravo 3 Gimbal Housing

    Howdy Have not seen one like that cracked. Transom bolts are torqued to 23 FT LB, so over torqueing will cause some issues. Other possibilities can be from having a soft transom. In any case its my opinion that your not going to fix it, it needs replaced. And you can upload pics after...

    4.3 GL won't run over 2000 rpms under load.

    Yes, or even harbor freight, just google "vacuum fuel pump gauge" it will show several. The issue is getting the fittings to fit the pump to carb with a Tee. You could order one of these which fits between the fuel line and carb. Might have one at AZ

    New motor installed and won't start

    Not a VP guy but do know your motor is not timed using a timing light. You have the HVS distributor and the motor is brought around to TDC on number one. Then the distributor is installed as in the pic below. There is no further adjustment unless its not running very well

    Volvo Penta MD2010 InstrumentPanel with Start button, electrical unit problem?

    My thought is this is something inside the alarm module. Your alarm module is part number 873737 Have been searching for the wiring of it and have come up with some older ones but not this one. In most cases a slight change is made and then another part number is used. The first one below is...

    Thunderbolt V timing

    The TBV has to be put in base timing mode to set. If you have a MSD box, I don't know. To put in base timing for TBV you ground the Purple/White wire and the set timing

    Alarm tan/blue tracer wire

    The wire is hot when the key is ON, but should not be when the key is OFF. Power comes from the purple wire going to the alarm. The alarm ground side is the Tan/Blue and goes to lube, temp and oil.

    Engine coupler swap out

    I would suggest not using the 92 one either because it is also worn. Note the points on the teeth, all are worn
