Mercruiser MPI 7.4L big block engines and gearboxes.

A pair of Mercruiser MPI 7.4L big block complete engines and gearboxes. They are 454 cu inch, 350HP freshwater cooled, approx1992, paired with Borg Warner Velvet Drive gearboxes. One motor is counter rotational. They are old school with Rochester Quadraport Carburettors, coil and distributer. They were rebuilt in 2018 including stainless steel valves, rebuilt carburettors, rebuild starter motors new alternators and come complete with maintenance records. They have been serviced annually since rebuild and have been used for approx. 400 hours. They are in good used condition. I am happy to negotiate including spares such as new manifold and riser kit, and Thunderbolt Ignition computer.
