This Plus Series 300 HP 100% New Quicksilver Inboard Engine replaces all makes of Standard (LH) Rotation small block 5.7L & 6.2L inboard engines.
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.
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
NOTE: Dealer must change driveplate if used with 71 & 72 V-Drive transmissions.
NOTE: Because this is a completely new engine and not a major repower assembly, the old engine being replaced is to be returned per EPA 1068.240.
