    Water coming out of bottom of engine area?

    Hey all, i'm helping my buddy with his 2000 Johnson 70hp outboard on his fishing boat, he started it up this year and noticed the pee stream was very weak, so I put in a new water impeller, then when I started it up I noticed the pee stream was still weak and also noticed water coming from...

    Low Fuel Pressure on 2000 Mercruiser 7.4 MPI

    Sorry, I thought it would be better to start a new thread because my original thread was just asking to identify a particular part. Is there any way to do an injector balance test without a scanner or will I need to buy one? I have the mefi 3/4 I had replaced the fuel pump first originally...

    Low Fuel Pressure on 2000 Mercruiser 7.4 MPI

    I've been trying to tackle this low fuel pressure problem on my boat for quite some time, my original symptoms was fuel pressure would go to 40 psi then drop to 20 psi with key-on engine-off, running psi would be 28 psi then 32 psi with vacuum hose disconnected. I've since replaced the fuel pump...

    What is the part number for this regulator?

    Just installed the new fuel pump but my pressure is still the same, running at idle it's at 28 psi and with regulator hose d/c it's at 34 psi. I guess i'll go ahead and try replacing the fuel pressure regulator next and see if that helps

    What is the part number for this regulator?

    I just bought a new fuel pump and it should be here Saturday so I'll install it and hopefully that fixes my problem, thanks!

    What is the part number for this regulator?

    Thanks! I'll definitely get one of those, can't believe they want over $500 for the OEM Mercruiser one, why is that one so much more expensive than the regulator on the fuel cooler?

    What is the part number for this regulator?

    I ran the engine and pulled the vacuum line when it was at idle, fuel pressure only went up from 28psi with line connected to 34psi with the vacuum line removed from the regulator.

    What is the part number for this regulator?

    Ok, I assume this is with engine running and not just key on engine off? I'll do the test hopefully tomorrow if I have time to make it out to the boat, and what would be a test to check if the regulator is bad?

    What is the part number for this regulator?

    I have the service manual for the 7.4 MPI and in the diagnostic flowchart it just says check for fuel pressure and if not correct, go to "OBD Check", then doesn't have any instructions that I can find after that.

    What is the part number for this regulator?

    How would you go about testing the regulator and fuel pump? I have the cool fuel system and the whole setup is in an assembly box that's real tight, not sure how I could get any connector in between the parts to test

    What is the part number for this regulator?

    Hey all, i'm working on my 2000 Mercruiser 7.4 MPI and ran into a low fuel pressure condition, when I turn key on engine off pressure spikes to about 40 psi then drops down to 18 psi, with engine running at idle pressure is about 28 psi. I figure the fuel pressure regulator may have failed and...

    2000 Cruisers 2870 Check Engine light blinking but no codes?

    Just made it out to the boat, so I tested the oil pressure sensor, temp sensor and drive lube sensor by unplugging then to see if any shut off the check engine light but it just kept flashing, also to note with key on engine off the check engine light would flash 2 times and then stop, but then...

    2000 Cruisers 2870 Check Engine light blinking but no codes?

    My drive lube level is fine so I'm guessing it's not that, what would cause a distributor signal interrupt?

    2000 Cruisers 2870 Check Engine light blinking but no codes?

    The check engine light on the console starts slow blinking steadily immediately after starting the engine but when I checked the codes in my Mercruiser 7.4 MPI it just gives me code 12 which should mean system is operational and nothing is wrong? Any idea where I should check to get the check...

    2012 Yamaha F115LA Leaking Lots of Water into Oil

    This one has me completely stumped, I'm working on a 2012 Yamaha F115LA that's leaking a large amount of water into the oil, after a fresh oil change and running the engine for just 3 minutes, the dipstick jumps from the low mark to way overfilled. So far I've already taken the cylinder head...
