    Merc 3.0 no start, just a click

    And I have also tried to jump red post at slave solenoid all the way to yellow post at starter, but just got a click again. Since that should have gotten 12v directly to the starter, I assume it must be the starter after all?

    Merc 3.0 no start, just a click

    I just tested voltage from the slave solenoid to the yellow wire small post connected to the starter. When I turn the key I am seeing a 1v drop between the slave solenoid and starter (which I think should be zero). When I test from the yellow wire post on starter to ground, I get 9.5-10v instead...

    Mercruiser 3.0 strange sound at low end acceleration

    Wanted to close the loop here in case it can help anyone else - I eventually brought it by a mechanic who offered to look at it for free. It was just a loose alternator belt. Feel like an idiot for not being able to figure that out myself! Humbling I guess… Also shout out to the mechanic who...

    Merc 3.0 no start, just a click

    Thank you for the peace of mind here. Just a couple other questions: What are the typical symptoms of a starter going bad, before it’s totally shot? For example would an occasional non-start as described above be a symptom? How about the starter motor needing to crank for prolonged periods (a...

    Merc 3.0 no start, just a click

    Hi all, Got stranded out on the water today and have done a lot of searching/reading on this site and testing since. I suspect my starter is to blame, but I was hoping for a quick sanity check before I go pick up a new one. This is a 2003 Bayliner with 3.0 Merc. Here is where I'm at so far...

    Mercruiser 3.0 strange sound at low end acceleration

    I have never been able to get it to make the sound on muffs. Seems to only happen when engaged in forward. I had considered whether it could be related to the alternator. When we bought the boat we hadn’t realized the serpentine belt was broken in the bottom of the engine bay (realized it a...

    Mercruiser 3.0 strange sound at low end acceleration

    Gear lube does look pretty clean (at least after removing some grime from around the vent plug). The boat has only been out once since I changed gear lube in the fall.

    Mercruiser 3.0 strange sound at low end acceleration

    Thank you both. I did change the gear lube in the fall before I put it away for winter. Putting in the recommended amount of gear lube at the lower unit left the level at the monitor in engine bay on the lower side of the “add” marker, but not by much. After running the boat for a few hours...

    Mercruiser 3.0 strange sound at low end acceleration

    Hi all, I have been struggling with a strange sound coming from my 2003 mercruiser 3.0 (serial begins 0m64). I bought the boat last summer and this problem started near the end of the year. Took the boat out first time this year today after changing all the oil and spark plugs in off season but...
