    Bravo 3 gear lube change gone wrong

    I've been servicing my outdrive and doing all the maintenance on my boat for the past 8 years, but yesterday I made a silly mistake. I drained the gear oil, cleaned the overflow reservoir, and proceeded to refill the outdrive. I always fill the outdrive until oil comes out of the vent hole...

    I have a 2005 Mercruiser 5.7 MPI Horizon and I am using a West Marine oil extractor with a garden hose adapter, but no matter what I do I can only suck about 3 quarts out, maybe 3.5 if you count what's in the oil filter. It is my understanding that the garden hose adapter is the preferred method...

    Can you help ID my sea water pump - something doesn't add up

    My engine is 2005 Mercruiser 5.7 Bravo Horizon MPI, serial #0w328501. I have a bronze sea water pump with a bronze cover, but my water pump cover has a replaceable SS wear plate (part number 8M2014176).

    Mercruiser water pressure sensor

    It appears that my water pressure sensor is faulty, which I understand is a pretty common problem. I found an older thread on this forum discussing possible alternatives for the "OEM" sensor, which costs about $140, and New Eagle was mentioned as possibly being the sensor manufacturer. I was...

    Mercruiser 5.7 MPI with Cool Fuel 3 module - should I add an additional fuel filter?

    I have a 2005 Mercruiser 5.7 Horizon MPI with the Cool Fuel 3 module. The fuel module has a built-in fuel filter, but I was wondering if I should add an additional spin-on fuel filter / water separator or not. It seems like a good idea, except I am not sure if this would cause too much of a...

    Mercruiser 5.7 repower options - the day has come

    Well, it finally happened. My 1995 (pre-Vortec) Mercruiser TBI gave up the ghost yesterday, right in the middle of our short boating season. Not a huge surprise considering it was a 24 year old raw water cooled motor with approximately 1100 hours on it. The question now is what to do next? I am...

    Aftermarket Mercruiser 350 harmonic balancer part number?

    Does anyone know what the correct aftermarket equivalent to Mercruiser's 75420 harmonic balancer? This is for a 1995 Merc 5.7 TBI/EFI. I believe mine is wobbling a little and I would like to replace it, but for whatever reason Mercruiser wants almost $400 for that part... I know that several...

    I have a 1995 Mercruiser 5.7 TBI/EFI with a Bravo III drive of the same vintage.

    1995 Mercruiser 5.7 TBI - tach not reading

    I have 1995 Mercruiser TBI/EFI engine with a Delco distributor, engine serial number 0F293683. I started the boat for the first time this season and I noticed that my tach is dead - it is not reading anything. The gauge itself is only 3 years old so I suspect the culprit is elsewhere. Where does...
