New 6.5L Marine OEM engine for all Peninsular Inboard engines, replaces 6.5L Turbo Marine Inboard engines.

This longblock assembly with Fuel System replaces 400 Series Only

This longblock product is only intended for replacement use with the 400 Series Peninsular engines, which are 6.5L and were produced from 1994 on up. This product option does not apply to 379 Series Peninsular 6.2L engines due to age and various obsolete configurations the 6.2 underwent. For 6.2 upgrade replacement support we recommend having the authorized rebuilder perform the changes using the bare longblock products only.

This is the preferred longblock replacement option because the engine is test run, new engine, new fuel system, everything is correct to run. Fuel system is tested and calibrated, and when engine is run the fuel injection timing is dialed in. Engine is ready to be dressed with your properly cleaned and inspected marine components for service. 

Note about Fuel Systems: when an engine is replaced, the old fuel system components should be replaced or rebuilt as by the time the engine is worn out, so are those components.

Current Peninsular Marine Engine Model VS Replacement Peninsular Engine Level

Keep in mind that your current power level engine has been configured to match the vessel and the marine gear transmission. The equipment on the engine matches the original level only. Many engine configurations were matched set with engine, marine gear and prop configuration. The different power levels were available from Peninsular even with similar engine equipment to adapt to the vessel and marine gear limitations. To change power levels from similar engines like a 270 to a 310 could lead to marine gear and related component failure quickly. Power level changes from what was originally equipped are also not covered under warranty due to damage to longblock that can be caused by insufficient engine hardware or from a marine gear transmission or drive failure.

New Replacement Longblock With Fuel System Includes:

  • Engine Longblock Assembly (engine, timing cover, balancer, covers, lift brackets)
  • Temporary oil pan to be replaced with your Marine Aluminum pan.
  • Block Heater (120 volt)
  • Oil Filter (filter and filter fitting)
  • New Fuel Injection Pump, Lines and Injectors, and mounting.
  • Fuel Lift Pump (pump, mounting plate, push rod)
  • Fuel Injection Line Hardware Mounting
  • New Glow Plugs (standard 12v systems only).
  • Timing Tab for Marine Mechanical Injection Pump
  • Block valley drain tube (safety component)
  • New Copper Nickel Engine Oil Cooler (must use).
Engine features all metric fasteners, so if replacing a Pre-1999 model Peninsular Engine, please inquire about a metric fastener kit necessary for replacing your existing engine.

This engine assembly will not accept turbo oil drain plate that mounts to the center of the block that was used on very late model Peninsular Engines from around 2010 to 2017 models. This can be adapted to the former turbo oil drain system where hose is used to connect to the side of the oil pan.

Recommended Components to Accompany New Longblock:

  • Engine Oil Cooler (included)
  • Aftercooler Gasket (aftercooler internal inspection/cleaning) *In Gasket Set
  • Air Filter Element
  • Thermostats - Engine and Bypass
  • Sea Water Pump Impeller
  • Engine Circulating Water Pump
  • Heat Exchanger (strongly recommend with new engine to replace)
  • Transmission Cooler (can be a restriction in cooling)
  • Turbocharger (fully rebuild or replace).
Note about replacement components: The components recommended to be replaced or re-manufactured (if re-buildable) are for the purpose of durability of the engine, these items are the minimum you should consider replacing, there are much more items (like hoses) that should be replaced but can be optionally sourced. Fuel system components are included because when an engine is due for replacement the fuel system components are worn out as well. Defective fuel system components (pump and injectors) can cause prompt damage to a new engine and will cause the engine to perform poorly if not absolutely correct.

Warranty

These new engines have been assembled with these fuel system components and test-run ensuring proper assembly and component functions. The engine assembly gets test run with the options for end engine usage. Injection pump is carefully bench tested and precision calibrated for every power level selected with matching injectors. Injection timing is verified correct per our specification and engine is ready to be dressed with your properly cleaned and inspected marine components for service. This partial engine assembly includes a 6-Months parts Warranty that starts upon delivery of engine, valid only when used with original inboard Peninsular equipment and application, and with proper core return. Retrofits and Re-powers replacing engines other than a Peninsular engine are not eligible for warranty. Changes (increases or decreases) in HP level from original engine to the replacement are not eligible for warranty as this causes equipment mismatch (engine equipment and gear/prop) that can cause damage to the replacement engine. This unit does not service other makes of 6.5L marine engines. Core engine must be returned to Unique Diesel within 60 Days of receipt of new engine, any warranty claims cannot occur without core engine having been returned.
