    Help with 5.0L EFI boggy

    Figuring without a serial number I would say yes 30psi is correct Boat needs a lot more fuel under load. Your plugs show running rich, but that can happen while idling Can also check timing advance, or if the ECM is getting a knock signal it will retard the timing You may have a MEFI-3 and...

    Main engine harness/starter ignition wire issues

    This is the color and had it made up to show how to start a motor without it being connected to the helm. So pay no attention to it The issue with the 10 to 14 pin is it also only uses 14 AWG wire and the main ground (pin 1) and hot (pin 6) need to be 10 AWG This is the helm harness plug...

    More Bravo overheating problems *sigh* Some advice before I haul the boat?

    Does sound like Bravoits or the inlet hose is kinked. If Bravoits it can be checked by removing the hose at the transom. The issue is I don't know how low the transom is to the water, so might have a problem. Being a fresh water boat until now I would lean toward maybe a kinked hose. There is...

    Mercruiser 4.3 lx gen2 2bbl fuel problem

    Trying figure out why it didn't run the pump when you bypassed the oil pressure switch. One side is feed by the key switch, so when its turned ON it should be there. If its not there then there is a break in connection. The purple wire goes to the ALT field winding's, the coil, oil pressure...

    Vapor lock issues

    Assuming your motor is a MPI (serial number are best) Running the pump by an auxiliary means will turn the pump ON but don't think this will stop VL. Installing a boost pump was something that Merc tried to fix the VL issue, but if you look in later years, this to was no longer being...

    Rinda scanner only test half of engine ?

    The scanner won't do a misfire test for your motor because it uses batch firing of injectors. Only ones that it will do a misfire test are those which have individual fired injectors like the 496 (8.1) This is an example of batch firing, 1-4-6-7 and fired at one time and 2-3-5-8 get fired at...

    Y pipe replacement

    Not for your year. The transom assembly has been changed and starting in 1989. You can have a one piece or 3 piece exhaust Y pipe. The 3 piece has other sealing surfaces which come into play. The bolt patten of yours is different then the more modern one Note the bolt patten is also different...

    Mercruiser 3.0 won't start.

    OK, then power is not making it to the slave relay Power passes from start terminal on key, to yellow/red wire, to neutral safety switch, to slave relay. The other side of the coil on the slave goes to ground. Turn key to start and hold there while slightly moving the throttle handle forward...
