Product catalog summary

Specifications:
The Westerbeke 80 is a marine diesel engine characterized by direct injection and natural aspiration. It operates on a four-cycle, four-cylinder inline configuration with a displacement of 230.2 cubic inches. The engine has a bore of 3.86 inches and a stroke of 4.92 inches, delivering 75 horsepower at 2600 rpm. It features a compression ratio of 16.5:1 and weighs 943 lbs. The cylinder block is a cast iron monobloc with wet-type liners and five replaceable main bearings.

Engine Components:
The engine includes a cast iron cylinder head with renewable valve guides, a nylon-coated steel crankcase, and a dynamically balanced crankshaft made from special alloy steel. The camshaft is a steel forging with integral cams, and the pistons are forged aluminum with a toroidal combustion chamber.

Fuel and Lubrication Systems:
The fuel system comprises a distributor-type injection pump with a mechanical governor, a fuel transfer pump, and a single-stage fuel filter. The lubrication system features pressure lubrication with an engine-driven gear pump, a full-flow lube oil filter with a spin-on element, and an efficient oil cooler.

Cooling and Electrical Systems:
The cooling system is fresh water cooled with an engine-mounted heat exchanger and a rubber impeller raw water pump. The electrical system includes a 12-volt starter motor and a 12-volt, 55-amp alternator.

Gears and Installation:
The reverse and reduction gears are hydraulically actuated with multiple disc clutches and a full capacity reverse band. Installation data includes mounting centers of 22.5" or 20", with a maximum installation angle of 12".

Standard and Optional Equipment:
Standard equipment includes a fresh water cooling system, raw water pump, heat exchanger, alternator, flexible mounts, propeller shaft coupling, hydraulic reverse gear, and a full-flow lube oil filter. Optional equipment includes an electrical instrument panel, high capacity primary fuel filter, 120 amp alternator, and spare parts kits.

Economics and Design:
The Westerbeke 80 is designed for marine use with a focus on dependability, durability, and ease of service. It offers excellent fuel economy, low service costs, and high resale value. The engine has been updated to meet modern environmental, power, and service standards, with improvements in valve size, combustion chamber, and injectors for better efficiency and fuel economy.
