Thank you, @alldodge. That looks like it's on the drive... I can't tell from the parts diagram but any chance it can be looked at with the drive in the water? Or will I have to haul the boat.
And just to confirm, this shift linkage/cam assembly is still a likely culprit even if the boat still...
Hi folks,
I think I've narrowed down the problem on the shifter. And I think the shift problem is an isolated problem.
I have a bravo 3, which shouldn't shift without the engine running. As it turns out, my lower shift cable moves with no resistance even with the engine off. When I disconnect...
Thanks scott. I'll check the pump and tstat.
Question on the neutral only button. Do you mean the button on the helm control? I was able to go into reverse just fine. If the button was just stuck wouldn't that stop be from going into reverse as well?
Hi all,
I have a Mercruiser 5.0L MPI engine w/Bravo 3 outdrive that has mostly been running great once I got some of the major problems resolved (new distributor/wires/plugs, etc.).
I've taken it out or at least run it on the dock probably once a week for the last 3-4 months. During that time...
Thank you! I will check the muffler, although a very preliminary check today with a stethoscope suggests that the noise is coming from somewhere near the rear (possibly).
To answer your question about the plug part number, I put in 8 new NGK BPR6EFS plugs. They are not iridium but it looks...
Yeah it's so weird. The strangest part is that this noise was NOT there last time the engine ran not even a week ago. I am trying to think through what I actually touched on this motor recently.... spark plugs, plug wires, spark arrestor, distributor cap.... I really think that's it. It's so...
Hi all,
First, I want to thank everyone who has helped with this so far. I completely redid everything "downstream" of the coil and the engine was able to fire up. I am not convinced that I would have been able to get this going without help, and I want to express my gratitude to you all...
Ooops! Yes, good catch... I meant:
1) I feel like I have very fast consistent spark off the coil....
2) Yeah when I sometimes DO get spark off the plug, it's not very often and it's definitely orange.
I'll edit my original post now to prevent future confusion but I appreciate the catch...
First off, I might be a hostile witness.... I would consider it more like an "accidentally ignorant" witness but I think the end result is the same :)
I feel like I have very fast consistent spark off the coil but I will take a video to confirm, so other can see the timing and double check my...
Thank you! This distributor actually has a repair plate already, it just wasn't on for this picture as I had to remove all of that to get the cap off. I think I misspoke... I didn't mean to make it sound like the cap was moving. By "very little play" i mean more like I felt like I could maybe...
Thanks all. Some responses for you all here....
I have verified that the rotor spins... kind of. The first thing I did when I got to the boat today was pull the dizzy cap off and after checking the compression in all cylinders, the rotor was in a different position. So it moves at least a...
Haha yeah, I definitely confused things with my "custom" numbering! My suspicion is that when I go to match up the wires with your diagram, they will be either very close or right on as the boat was running pretty well before. Whatever this issue is, it's something that could progressively get...
Thanks. Just to confirm.... that distributor photo that was in my post followed my (almost certainly incorrect) numbering on the engine diagram that was also in my post. So I think I confused things by using my own numbering and just tossing it out there.
Can I confirm that this is the correct...
Thanks for saying this! I appreciate the pep talk and the reassurance that at least one person appreciates all the detail... sometimes I worry that people see a wall of text and find it annoying :)
Anyways, I have more information. Three new pieces of info:
1) Compression test seems good...
Ok, so new information.
I went down today with a spark tester. I tested a few plugs and was getting no spark. I tested the wire coming from the coil to the distributor and I was getting nice healthy spark coming off the coil. So, the issue must be somewhere between the coil and the...
