    5.7 EFI TBV won’t start unless spark plug boots reversed

    SOLVED!!! I got ahold of my Mercruiser buddy north of me. Distributor CAN move from the spindle at the oil pump. When replacing an oil pump you must be very delicate or have to retime your engine. Moved engine to Top dead center compression on cylinder number 1. Marked where cyl 1 is on my...

    Yes. The dist is identical to that diagram. First part would have been cap and rotor but a lot at one go before test running

    Agreed. I always make sure the notches align for install.

    Also, on these timing covers there’s a raise with a Notch, is that for TDC? In effect a replacement of the “teeth” that came on the engine

    Not at a dealer currently. Service shop yes. Hope to work for a dealer in future to get back on G3 diag and such. I’ve had crossfire before. That was from a Bad plug wire though. Will check for that here Will also try the old cap and rotor

    Should I set initial timing if the distributor hasn’t been removed? Boat ran well last season

    Copy on all. My tune up annually is oil, clean connections, fuel treatment year round. Fuel filter. Oil filter. New coil coming due to rust and just simply want to write everything off 100%. I’ve done all appropriate testing. Inline spark test, spark gap, plug gap, fuel pressure, etc All...

    Replacing Gimbal steering seal?!

    A lot of surgery and a lot of patience. That coming from a marine tech. Even I hate doing it. Follow the step by step thought and you’ll be fine once you get through the season

    Starts and runs when swapped. Fuel is there. I checked spark. Spark is there. EFI injectors going strong. IAC whistle comes and goes. Concluding that it’s working(to a degree. Spark present means ignition sensor in the distributor is working. Any other ways the timing could have been thrown...

    5.7 EFI TBV won’t start unless spark plug boots reversed

    Pulled my Merc 5.7 EFI for a bunch of tune up work as I re did the transom assembly. Put it back in. No start. Figured somehow I had the plug wire placement wrong so I flipped them around. Then it started but “lean” pops and sputters a bit. It will idle but barely when under load and sometimes...

    Replacing Gimbal steering seal?!

    Hey Mark, Just finished screwing with this. Go to JR marines website and find their videos for installing their kit. Good videos. Things you’ll need to watch out for: Gimbal ring being stretched(need a new one cuz it won’t tighten down) Needing a new u bolt and nuts. Do this regardless...
