    help help help overheating Mecrusier

    Did you happen to check for / replace the two o-rings on the inside of the tube that connects directly to the impeller housing and slides into the upper drive when you reassemble? I just replaced my impeller a few days ago for the first time and my first thought when installing was if those...

    Ross Barnett Reservoir Mississippi

    Seems like a long shot that I'll find anybody on the forum here who boats on Ross Barnett in Central Mississippi, but if so give me a shout - lets meet up this summer! I'll be out just about any Saturday that is above 80 degrees (which basically means every Saturday in the Deep South). I've...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    Well I have some embarrassing news. After getting to my hands and knees in the cockpit I made the unfortunate realization that the aftermarket depth finder somehow has the absolute same "beep" as the ignition/engine trouble beep. I only was able to realize that with my head in between the DF and...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    Quick follow up after getting everything buttoned back up. IR readings after 15 min with some revs in the driveway (previous in parenthesis); starboard: manifold 95 (155) riser 105 (160) elbow 95 (155) port: manifold 92 (120) riser 98 (100) elbow 95 (100) Here's to hoping this solves my...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    I had the IR gun on board last Saturday and after a WOT run the starboard riser showed 165, 140 on the port. I figured the impeller wouldn't be THAT bad if I wasn't even clearing 175 degrees. (I also thought they were known to break apart rather than the more 'melted' look of this one). I'm glad...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    What more needs to be done after oil change, filter, fuel filter, new thermostat, new impeller, and gear lube change? There surely can't be too much more :ROFLMAO: I was thinking upper drive / bellows at the end of the summer since I'm not having any water intrusion issues.

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    Got parts in for the impeller, so I cracked open the lower for the first time. I'm wondering if this is bad enough to cause low pressure / high temp and trigger an alarm. It doesn't really ad up given the conditions that alarm triggers. Regardless it needed to be replaced. Also should have a new...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    If the oil pressure switch can trigger an alarm without the engine running, would you be inclined to replace that first just to get that off the list of possibilities?

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    Found serial number tag; L653238. Can ya'll confirm exact engine name so I don't look dumb in the future! As far as other comments go, it is 100% the audio warning buzzer pictured above making the noise (and this is the same buzzer that emits a solid beep when key is turned to run but engine...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    My bad, I thought EFI was the fuel injection and MPI was the carb version. Still learning!

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    On the chance it is engine temp related, I just ran it on the muffs for about 15 minutes and used an IR gun. I've read strbrd/port temps can vary but this is what I got. After idle and some revs; starboard: water pipe 110 manifold 155 riser 160 elbow 155 port: water pipe 100 manifold 120 riser...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    I believe it has happened with just battery on, no key involved, as well as key in ignition but not switched to run or start. This has only happened a handful of times, whereas when I am in the water with engine running idle or at speed, its almost guaranteed to beep randomly. Unfortunately...

    Intermittent Alarm Beep - Mercruiser 5.0 V8 MPI

    I'm starting to lose my mind on this one as nothing adds up. I've brought a 2000 VIP Vixen back to life and she runs great. Had a fun time rewiring nearly everything, new starter, new audio components, trim pump rebuild, oil change, gear lube change, etc etc, and have had a few great days on the...
