What is this gadget ? It bolts straight to the diff banjo , It's either a retarder , a planetary reduction of some sort or a hydrostatic or electric drive unit . It would be more than just a pinion housing .
Mercury switches cut the fuel off , killing the engine before the oil pressure gets low enough to shut the engine down via an oil pressure sender unit . Which would be a better method of shutting it down as if the engine is at full noise and relying on the low pressure unit to send the signal the crank could do another 500 revolutions before it stops . Which is plenty of time to melt Babbit Metal and destroy the engine .
