    While your workaround may be working for now, I am sure you can appreciate that this is not the way to go. Best to find the issue and solve it. And I know this forum can help get you there. I am unsure of your configuration. Best to post engine serial no. for those who can help better to be...

    2003 Glastron VP 5.0 GL Overheat issue

    OK, so let’s reset and start at the beginning: a new to you boat and had 30 hrs last season of no issues. What changed? Ie did you do an impeller replacement and now it overheats? Please provide in chronological order what was done (maintenance wise) and when started to experience overheating...

    2003 Glastron VP 5.0 GL Overheat issue

    There are many things that can cause an overheating situation. They range from the intake hoses in the sterndrive are sucking air, to the Raw Water Pump (RWP) (aka seawater pump) not working properly to T-stat, to blockage in the output, etc. So before jumping to the conclusion that it’s the...

    2002 Crownline 5.7

    I had a similar problem on my 2005 VP 5.0 GXi-E when I first got it. Kicked my butt and my local marina’s as well (neither of had scanners). Was taking a similar approach (shotgun parts) and eventually found my MAP sensor was all crapped up due to ‘belt dust’. Cleaned it up and ran perfect. Also...

    RPM after serpentine belt change

    It’s not unusual for tachs to go a little wonkery as they age. What typically happens is the 4/6/8 selector switch on the back of the tach gets a little corrosion under it and causes it to misread. My suggestion: get behind the tach if you can with a flashlight and find that little sliding...

    Cant start engine when opening throttle. Mercruiser 3.0

    While there is an issue with the control / neutral safety switch I am curious as to your starting procedure. Reving a cold, just started, engine is not good but I suspect you mean that you have learned it starts best if it is slightly above idle. Post repairs per above, and assuming a carb’ed...

    Engine Not Running

    Frankly I am confused or perhaps simply ill-informed. I do not understand how the engine can run without the intake plenum (manifold) nor do I understand that it only runs a full throttle > is the RPM raging at 3K or 4K and without cooling water?! > or it is barley putting along even though the...

    2006 volvo penta 5.7 rebuild help

    Giving your money constrains and experience my suggestion is let the teardown be your guide. Develop your minimal basic plan on the inspection after teardown. And if still have some bucks to spare start adding in elements a la carte where the menu items are listed in priority order of need with...

    Compression test

    As the others indicated, you should be good to go and if you desire to investigate more, that can be done. However, I am concerned about your symptoms to get up on plane. A V-8 5.0 with low compression (but not that low) on only one cylinder I would not expect to significantly degrade the...

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

    Based on the original symptoms after just putting on a new cap and rotor my thoughts were there could be an issue with distributor wiring arrangement. After your pictures of which wires went were, I felt sure there was some ‘crossed wires’ hence the suggestion to validate. Note: by “crossing” I...

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

    Searay I have been offline for a while so just reading thru your success (congrats!) and next issues. A couple of things if you do not mind. While glad simple as cap and rotor, which we were all thinking, I am curious about the suspicion that a couple of the plug wires were ‘crossed’ and on the...

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

    These sentences appear to be conflicting. Recall you need the snap, snap, snap rapid fire off the coil, less so off the spark plug wire. Is sentence no. 2 for the plug wire and not the coil?

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

    I have not used that particular cap and rotor but its on my list to do so (I too have a 5.0 MPI but VP, same engine base). I see no issues with it and it was recommend. Recall you are our ears, eyes and hands. If you are 100% confident have voltage at both key positions, I will avoid the Click...

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

    I am not positive on your engine, but the coil may get power in two different ways: One while the starter is engaged (key in the start position) Two when the engine is running (key in the run position) Need to find a wiring diagram for your engine, please search around on the forum at the Don...

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

    After some good sleep, well not really > I was bothered by not picking up on your unique wiring numbering, so perhaps a little of that anxiety was creeping into me. First off do not need to replace the dizzy unless it is mechanically compromised. When you try to twist the rotor is ok it twists...

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

    Oh, the great news is the compression numbers! You have a solid engine but I am concerned about the black plugs that indicate its running really rich. With a sound engine, all else is easy, relatively speaking. So you will get this solved. Perhaps that is a pep talk I need post putting foot...
