    Fuel Injector Question

    Next question because I can't seem to find the answer in the service manual. What kind of o-ring lube to use? I googled it and the answers are all over the place....use engine oil, ATF, silicone, vaseline. Which one is it?

    Fuel Injector Question

    I went to pull the fuel injectors so I could send them off to be cleaned. Since this is a 2005 boat, this is probably the first time they've been pulled and they gave me a little bit of a fight. Some of the injectors popped off the rail rather than out of the manifold so I hope I didn't do any...

    How to get Navionics on a large screen at the Helm

    You can get Navionics on Garmin. Garmin bought Navionics not too long ago. Also Lowrance supports Navionics. I've been using a Lowrance GPS for the last 5 years along with a Navionics subscription to keep the charts up to date. I love the sonar cartography.

    Battery charger size needed

    I've been reading up on how to determine what size charger is needed. Some things I've read is to take the amp hour rating and multiply by 10%. Based on this, it looks like I would need a 20 amp charger (10 amps per channel - 2 batts). But then I've also read that I wouldn't need a 20 amp...

    Fuel Pressure Regulator - Automotive equivalent

    Why are some regulators way more expensive than others? For my engine (2005 6.2L MPI), 885174, it averages around $300. I know there have been many posts regarding the use of Merc parts versus the automotive equivalents. Is there an automotive equivalent for this regulator? I know there are...

    Red lights above bilge blower switch

    I don't have a fume detector or gen. This is a new issue I noticed this year and now I can't remember if both lights used to be on or off when the blower switch is on. I'll give Chap a call and see what they say.

    Red lights above bilge blower switch

    With my Chap 256 SSi, I have two red leds above the bilger blower switch. One of the leds is lit when I turn the switch on. At first I thought this was an indication that one of the blowers was not working but that is not the case as both blowers are operating. What's the wiring schematic...

    Fuel Injector Boat vs. Auto Equivalent

    Basically just asking the question. Just hearing/reading things where some folks take the automotive part route because it's way cheaper but I also recognize cheaper may not always be the right path to take.

    Fuel Injector Boat vs. Auto Equivalent

    What's the consensus on using the automotive equivalent of fuel injectors on boats? I looked up the price for injectors (Merc #885176) for my 6.2 MPI and of course my draw dropped. What would be the automotive equivalent to this injector?

    Diacom engine parameters

    I called Rinda. For the ECM/PCM-555, you have to read the fault history to get the engine hours along with the breakdown of hours/rpm range.

    Faulty IAC or something else

    Got caught up in some business travel....catching up on this issue. I will take a look at the TB, however, I did go out on the boat over the weekend and it ran fine....no in gear/idle stalling or stinky exhaust smell. I guess I'll just keep an eye on things as the season goes on.

    Diacom engine parameters

    I purchased the Diacom software but I don't see "engine hours" on the list displayed. Is there a way to see this bit of info.

    Faulty IAC or something else

    To continue my investigations, the duty cycle started to act differently this time around and there was no real smell of rich exhaust this time. Run #1 -Engine at temperature -RPM 550-580ish -Removed the air hose between the throttle body and IAC and RPMs jumped closer to 600. I guess this...

    Faulty IAC or something else

    I don't see injector pulse time on the parameter list. Fuel pressure settles to around 40 psi once the pump finishes priming. Sits around 48 psi at idle and around 45 psi @ 1000 rpms. I'm running on muffs so I'm not sure if I can go as high as 1800 rpm.

    Faulty IAC or something else

    Looking at the system info the engine may be a 2004. "04MY 6.2L BRAVO"

    Faulty IAC or something else

    I guess my signature is not showing....I have 2005 Merc MX 6.2L MPI with B3 with the ECM-555. Serial number starts with 0W061xxx. I don't see Injector pulse listed as a parameter. I need to pick a fuel press gauge to see what's going on there so that will be next.
