    Please revisit this stalling with me.

    2001 310 Sundancer w/2011 5.7 mercruiser horizons. It has been very, very difficult to find a mechanic to come out to the boat and scan. Long story but I've been trying to get the scan done throughout the many posts. With that said, I really appreciate your patience and help. -The engine...

    Missing fuel filter

    2001 310 Sundancer with 5.7 mpi Horizons. I can't find the fuel filter/water Sep on the starboard side. The one on port is attached to the fuel tank so you can't miss it. Finding a big white can shouldn't be hard but I don't see it. Thoughts? Thanks John

    Why is my fuel pump roasting its 20 amp fuse?

    2001 310 Sundancer with 2012 v-drive 5.7 mpi mercruiser engines. Drove the boat 10 hours straight. It ran perfectly. Right after I throw the dock line the starboard engine stalls. Help here led me to a 20 amp fuse that was blown. Replaced the fuse and it started and ran great as I moved it a...

    Fuel pump turning on independently

    Hi everyone, my starboard 8.1s horizon engine has been acting strange on my 01 380DA. I'll turn on the batteries and a few minutes later I'll hear the systems monitor beep, with a message about a starboard engine issue. At the same time, the starboard engine fuel pump will activate for 2-3...

    2005 240 Sundeck, replaced electric fuel valve, still won't stay running

    5.0 Bravo 3R, the boat has an electric fuel valve which has a line from the fuel tank to the cool fuel box with the fuel pump. The valve became too hot to touch and the boat would not start. I just replaced the valve. My understanding is this valve shuts off the fuel in case of a fire and has to...

    So I am finally going to install fuel boost pumps on my twin 4.3MPI engines to hopefully once and for all fix my vapor lock problems I've had over the years. My simple question is...for those that have them installed on their 280DA (or similar twin engine Sea Ray), where is the boost pump and...

    Anyone ever replace the port side cool fuel pump assembly on MPI engines?

    So I'm an issue keeping my engine from running. The engine shut down on me a couple weeks ago while at idle, docking the boat. Couldn't restart. Dug out the fuel pressure gauge and determined I had no pressure, and then realized I couldn't hear the fuel pump prime when the engine switch was...

    Vapor Lock 2013 Edition

    And so, the saga continues... Over the last couple of years I've been battling vapor lock in my twin 4.3MPI's. I've gotten better about dealing with it and preventing it but in some circumstances it's hard to avoid a scenario that will make it happen (re-fueling at a fuel dock, fishing). Over...
