    5.0 Mercruiser MPI Question After Stalling On Me This Weekend

    Need to try adjusting your shift interruptor switch first. If that works then your good to go. If that is no help then need to replace the shift interruptor switch.

    1999 7.4L mercruiser fuel pressure regulator crossover part?

    Reg is used on your L29 and some 8.1 is a damper on fuel rail Should be 43 psi (same as cool fuel Reg) but unable to verify. Other part numbers are 802630T01, new 8M0069803, (43psi) Sierra 18-7663, Crusader 49063 IMO the part should interchange but maybe @Fun Times might have some insight...

    It runs fine for 5-10 minutes, then it starts missing and plugs 4-5 are black and wet. Plugs 1-2 look fine (cream color or brown). Compression is around 150 on all cylinders. Something listed above is not correct Even if the firing order was not correct would not produce what is listed
