QUICKSILVER PLUS SERIES ENGINES

QUICKSILVER PLUS SERIES ENGINES

The PLUS‑SERIES ENGINES from QUICKSILVER are 100% new construction, and contain all the parts a CRATE ENGINE lacks. These are
drop‑in‑ready new marine engines. Based on popular MerCruiser and Mercury Remanufacturing models, these are 100% new engines that are built
with marine‑grade engine internals and other NEW marine components. QUICKSILVER PLUS‑SERIES engines are 100% new factory engines for
repowering classic boats built before 2008 in California, and prior 2010 for the other 49‑states. Because these are completely new engines and not a
major repair assembly, the old engine being replaced is to be returned per EPA 1068.240.
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 customer preferences or the specified installation requirements found in the Repower Reference Manual
included with the engine
