Since the focus of PLUS‑SERIES ENGINES is repower, many parts included in new MerCruiser engines used for new boat construction are not included. Parts such as: transoms, trim pumps, Y‑Pipes, rigging, props, boat harnesses, riser kits, closed cooling kits, steering cylinders, lubes, and many other parts required for a successful repower must all be purchased separately.

Adapting Plus Series engines to specific applications may require some parts to be transferred from the engines coming out of the boat or purchased separately. Examples include:
• Transfer of flywheel housings, couplers, and other hardware to adapt to various makes of drives and transoms
• Changing engine couplers to match specific transmissions, or customer preferences
• Changing engine mounts from front to side, or using solid engine mounts
• Use of various Quicksilver kits to meet your preferences or the specified installation requirements found in the Repower Reference Manual included with the engine
