    2005 Mercruiser MPI 5.0L misfiring(?) when in gear, idles fine

    No you are correct. I missed that this was your unique wiring system. Yes, the front of the boat is front of vehicle. This just goes to show you that when I post past my bedtime, i miss stuff. I will think on this more... sorry...

    2005 Mercruiser MPI 5.0L misfiring(?) when in gear, idles fine

    SeaRay, You’re welcome and I tend to be verbose as well, so we share that habit but it just saved you. Also, I sense that anxiety creeping back in :) There is NO reason to get another distributor. Your wiring to the cap is incorrect. I used your pic and put in blue text the correct plug...

    2005 Mercruiser MPI 5.0L misfiring(?) when in gear, idles fine

    Searay, please pardon my jumping in late on this. First off, I really appreciated reading your complete and descriptive postings. Believe it or not but a lot of folks will say: “Motor will not run, please help.” What you understand is that you are the eyes, ears and hands for those trying to...

    2004 5.7 GXI Overheat - Pump? Impeller?

    OK, now time to get to work :-) Do all that backflushing and checks as per above. Pulling off the hoses will be much easier with a tool set like this link. If you do not have one, trust me, get it. Also while pulling hoses give them a squeeze in the middle. Does it feel like you are crumpling a...

    2004 5.7 GXI Overheat - Pump? Impeller?

    Correct, on muffs, do not run it up, perhaps 1500 max but only for 10 seconds or so. Also, you may be able to run it on a hose without muffs connection. Read the attached. While you cannot replicate running it on the lake you can still do your investigation per above. Also please provide what...

    2004 5.7 GXI Overheat - Pump? Impeller?

    Let’s see if we can get the conversation started and get you back on the water with confidence. First off, a small drip fm the Raw Water Pump (RWP) would not impact the temps. And putting in a 150 t-stat is not addressing the root cause. A little more info on the boat would be helpful...

    5.0 GXi fuel problem

    You’re welcome. But the key to getting this solved is to answer the questions fm Scott and All Dodge. Do not be shy about asking questions, it the only way folks can help but in return you need to answer theirs. Troubleshooting is a logical step by step approach and without data / info, the next...

    5.0 GXi fuel problem

    Not technically a fuel cell but it is an assembly of a low and high pressure pump, hence referred to as a cell sometimes. Yes, these pumps came with internal paint that would flake off over time and cause havoc. This thread (link) is a collection of good info on this and what to do about it...

    Tensioner Replacement

    There may be a pin behind it to keep it fm rotating on that single bolt so be cognizant when reinstalling to get it all lined up correctly

    Volvo/OMC Raw Water Pump Repair/Replacement

    Unsure if you will get a consensus. My recommendation due to the age is get a new pump. While a seal kit may do the trick the 30-year pump may be worn in its shaft, chamber, etc, such that even with a new seal kit it will still leak. This post by @Scott Danforth (link) may lead you to an OEM...

    Won’t Start in the Water

    Solving the starting problem is great news! And how frustrating on the next issue. Keep thinking about those grandkids! Is the 'not matching what you expect due to RPMs' the same for forward and reverse? If yes, it could be a spun hub for the prop or a bad coupler. I am not familiar with your...

    5.0 GXi fuel problem

    I believe this a MPI engine and thus subject to the VP fuel cells had internal paint that breaks down with ethanol gas. The resulting chips / goo can easily plug up the pressure regulator and / or the injectors. This issue is typically associated with a fuel pump whine as well as the pump...

    Is my motor healthy?

    The idea was to compare the motor idling with and without the belt. Both new vids have the belt. Also did you check the pulleys as suggested?

    3.0 exhaust manifold over heats

    Ah, I see. You are right of course! I was looking only for water downstream of the manifold and saw that. No coffee yet is my humble but not worthy excuse. :-(

    3.0 exhaust manifold over heats

    Lou, Thanks for the validation about the oddity of no flow in manifold until t-stat opens > I am always trying to learn so I appreciate the follow on “why” as well. For the elbow getting constant water, it seems it does via the ‘bypass’. I pasted a section of the diagram below highlighted with...

    1998 Volvo/OMC - When shifting to forward, the motor stalls. It runs fine on muffs.

    Lou, Not sure I understand about the water. OP can start the boat post launching and after stalling, able to restart and run it up in neutral. Thanks.

    Gauges don't work

    “Sad diagrams” still carry the point, so all is good, thanks for the info. While I am not familiar with the older boat designs, current boats (I assume) follow the protocol of the fuses protecting the wiring and not the device. For example, my 2005 Larson does not have fuses for each gauge. The...

    Gauges don't work

    As highlighted, these are daisy chained together and thus if other gauges are working, then is probably not a fuse issue. Example: does the Oil Pressure gauge work? If yes, there is power and ground to that daisy chain. While it may be a the daisy chain connection to these particular gauges...

    Is my motor healthy?

    Agree hard to compare. Also do not run it long without the belt but that is a good troubleshooting technique. With the belt off grab each pulley and spin it by hand and also try to rock it back and forth (using two hands, put one on each side of the pulley and push with one hand while pulling...
