    Merc 350 Mag fuel problem

    You can purchase a decent fuel gauge on Amazon for $30. I am going to create a bracket to hold the gauge and an old iphone or GoPro and record the pressure as it would be difficult to watch the gauge under power with the engine cover up. Any thoughts on this idea.

    Merc 350 Mag fuel problem

    Is it safe/feasible to do this test while cruising on plane? It is good to know that I can spend the time necessary to try and duplicate the problem. I think I can replicate the problem during the first ten minutes of idle given enough attempts from a cold start. The problem is very erratic!

    Merc 350 Mag fuel problem

    My mechanic replaced the fuel module in my 2009 Merc 350 Mag engine after it failed and only allowed me to idle into port. Since the fuel module replacement I have had erratic starting and occassional engine stuttering early on in my cruises. Once underway it will cruise for two hours with no...
