Across these eight sections, this Chrysler Marine LM318/360-BW manual gives a technician everything needed to move from routine upkeep into full mechanical overhaul work on either displacement variant of this 90-degree V8. The specification tables carry parallel 318 and 360 cubic-inch columns side by side, so a mechanic working on either engine reads the correct clearances, torque values and service limits without cross-referencing a separate book. The narrative sections on cooling, carburetion and charging system diagnosis read like a bench technician’s notes rather than a dry parts list, walking through disassembly, inspection and reassembly in the same order a shop would actually perform the work.

Engine Identification and Firing Order

One section of the manual is devoted entirely to reading the Chrysler Marine name plate correctly — decoding engine model, carburetion and final drive letters, propeller shaft rotation, and reverse gear reduction ratio directly from the stamped codes. This matters because the LM318/360-BW manual also documents that firing order differs by rotation: R10, R15, R25, R30 and L19 engines fire 1-2-7-5-6-3-4-8, while L10, L15, L25, L30 and R19 engines fire 1-8-4-3-6-5-7-2. Getting this wrong during a rebuild or a distributor timing job leads directly to a no-start or a rough-running engine, so having the manual’s own decoding chart on hand before you start is worth more than guessing from a generic small-block reference.

Own This Chrysler LM318/360-BW Manual

With this manual a technician can carry out a complete cylinder head rebuild, water pump and thermostat service, Quadrajet carburetor overhaul, alternator and battery diagnosis, and full winter lay-up or spring fitting-out on either the LM318 or LM360-BW engine, using the exact clearances, torque figures and procedures Chrysler Marine’s own service department wrote for these units. Working from the correct factory figures rather than a generic small-block guide protects against reusing an out-of-spec bearing, mistiming ignition on a reversed-rotation engine, or overfilling a crankcase whose capacity actually depends on pan style. The manual downloads instantly as a PDF after checkout — no shipping wait — and can be read, searched or printed from a phone, tablet, laptop or shop computer whenever the engine is open on the bench.
