Boat part number 1108655 is a new 2021, 4.5L, 250 HP, Alpha MPI inboard engine from Mercury Mercruiser, part number 40450039U .
Designing a V6 block solely for marine use allows Mercury to build the 4.5L with the ultimate protection system, using cast-iron components where the engine intersects with seawater, and using corrosion-resistant aluminum and composites everywhere else.
Thanks to its new, long-runner scroll intake manifold which draws in more air and converts it into additional torque, the 4.5L delivers a ground-breaking power-to-weight ratio and gives you V-8 power in a V-6 package. The 4.5L’s newly designed rear-facing throttle body, anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel-supply module, and structural oil pan all work together to deliver a superior idle, smoothness and low vibration. Resulting in an exceptional driving experience.
