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...
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). The confusion comes from the fact that I don't see the wear plate listed in the Mercruiser...
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...
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...
Bought a used 2005 Mercruiser 5.7 Horizon MPI engine - things to inspect/replace before I drop it in?
I purchased a used 2005 Mercruiser 5.7 Horizon MPI engine setup for a Bravo drive, serial number 0W3285##. The engine has 1050 hours on it, verified with VesselView. I got the engine at a fair...
I found another motor that I am considering purchasing and I was wondering what is the easiest way to verify the engine hours on a ECM555/PCM 555 equipped motor? One option which I think would work is Mercruiser's VesselView Mobile, which can be bought for ~$200, but I was wondering if there's...
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...
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 3 outdrive, approximately 800 hours on both. I am getting a slight vibration in the engine with the drive removed, usually around 1000RPM. With the drive installed, I get the same slight vibration in Neutral, around the same RPM. Once I put the...
I have a 1995 Mercruiser 5.7 TBI/EFI with a Bravo III drive of the same vintage. I am going through my pre-season checks with the boat sitting on a trailer and I seem to have some sort of vibration, which is most noticeable at fast idle - 800 to 1000rpm. The vibration is present with the drive...
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...
I know that I would most likely have to re-power sometime in the next couple of years, and I am simply trying to gather some information ahead of time.
Currently I have a 1995 Mercruiser 5.7 TBI/EFI with a Bravo III. The engine has a MEFI-1 computer and a Delco EST/HEI distributor.
If I was...
I am trying to find the correct procedure for setting the base timing on my 1995 Mercruiser 5.7 TBI, engine serial number 0F293683. The engine has MEFI-1 ECM and a Delco EST distributor.
I had to remove the distributor in order to replace my intake manifold and now I need to set the correct...
