    Mecruiser 5.0 EFI injector cleaning

    I have twin 5.0 l mercruisers, Serial # 0M069661 and 0M069669 with EFI and about 900 hrs. I was planning to send my injectors (13) out for cleaning. Before removing, I looked at the illustrated parts breakdown (attached) and it shows O-rings and gaskets (13,14) used in the installation which...

    if you think you have a gas problem?.

    I posted this in the mercruiser trouble shooting board, but since this applies to all boats, I though I'd repost here. I have a Chaparral with twins. At the same point in time, Both engines developed exactly the same problem, pretty much classic vapor lock. I was convinced the gas was bad so...

    Old fuel - Vapor Lock?

    2001 5.0l EFI. I'm pretty sure I have a Vapor Lock issue. After shutting down, engine water gage temp has to be below 125F to start (takes about an hour to cool from 175F running temp). I have twins, both engines act identically. Fuel is about 6 months old (150 gallon tank) and I always...

    Chirp from 5.0l with alpha drive

    I have a 2001 chaparral 280 ssi with twin 5.0l and alpha drives. I have a low frequency ( roughly every 4 seconds ) coming from the starboard engine. It is a "chirp" as opposed to a squeal or squeak. What bugs me (other than not knowing what it is), is that I cannot find anything on the...

    Anyone had issues with "recreational grade" non-ethanol gas

    I know what Vapor lock is and how to prevent it (if you're interested see this link http://en.wikipedia.org/wiki/Vapor_lock.) This weekend, three boats including mine experienced vapor lock. None of them driven very hard prior to shutdown, ambient temp in the mid 80's. All mercruisers, one 4.3...

    Vapor Lock -

    OK, three boats in one weekend, including mine experienced vapor lock. None of them driven very hard prior to shutdown, ambient temp in the mid 80's. All mercruisers, one 4.3 v-6, one 7.4l V-8, and mine, twin 5.0L. All restarted and ran fine after a couple of hour cool down. The only thing...

    Installing Perko Fender Locks

    Re: Installing Perko Fender Locks I am sure a lot of people have had success with fender locks, but not me. I installed some on a pontoon boat and they were broken during the first season. They did see a pretty good load. While rafted to larger boats, wakes from passing boats would move the...

    Flip up bolster for double helm seat

    Thanks in advance for any help. I have a 2001 280 SSI. Love the boat, especially the double helm seat. For this years model, however, it has a failry screwy "flip" up bolster. I've never been able to really use it, it doesn't really flip up, just sort of hinges up in the middle of the seat...

    Mercuiser "lockout" switch?

    I have a 2001 Chaparral with twin 5.0l mercurisers with alpha drives. On occasion, the starboard engine appears to be "locked" out when trying to start. When the key is turned, the alarms sound but zero sound from the starter or starter solenoid. If I start the port engine and bump it into...
