Product catalog summary
Introduction
This document provides an overview of marine engine cooling systems, focusing on water-cooled marine petrol and diesel engines. It discusses the limitations of direct cooling and keel cooling, and highlights the advantages of heat exchanger cooling.
Marine Engine Cooling Systems
There are three primary methods for cooling marine engines: direct cooling, heat exchanger cooling, and keel cooling. Direct cooling with seawater is discouraged due to potential engine damage. Keel cooling is suitable for small boats but has limitations due to external pipework. Heat exchanger cooling is the most effective, isolating seawater in corrosion-resistant components.
Bowman Heat Exchangers
Bowman heat exchangers are high-quality products with advanced materials and features. The tube stack is fully floating to minimize thermal stresses and can be easily removed for cleaning. The design ensures the system is self-venting and prevents aeration of the engine water circuit.
Installation and Configuration
In marine engines, components in the seawater circuit are typically arranged in series. The gearbox-oil and engine-oil coolers are on the suction side of the seawater pump, while the heat exchanger and any seawater-cooled exhaust manifolds are on the discharge side. For turbocharged engines, the charge air cooler should receive seawater first to achieve the lowest possible air temperature.
Exhaust Manifold and Additional Features
A water-jacketed exhaust manifold is necessary to reduce engine-room air temperature. Bowman offers a combined water-jacketed exhaust manifold with a heat exchanger and header tank, suitable for small series-produced engines.
Conversion of Automotive Engines
When converting automotive engines for marine use, the existing centrifugal pump should be retained for the freshwater circuit, and an additional pump should be fitted for the seawater circuit. The seawater pipe bore should be selected to maintain appropriate flow velocities.
Recommendations and Best Practices
Ensure the seawater outlet from the heat exchanger is from the upper connection to keep the tube stack full of water. The gearbox cooler size depends on the transmission type but is usually smaller than the engine-oil cooler. Freshwater-cooled oil coolers can be used but require larger sizes due to higher water temperatures.
Conclusion
Bowman provides comprehensive solutions for marine engine cooling, emphasizing the importance of proper installation and maintenance to ensure optimal performance and longevity of marine engines.

Bowman Marine Engine Cooling There are three methods employed for water-cooled marine petrol and diesel engines: direct, heat exchanger and keel cooling. Direct cooling of the cylinders and heads by seawater is unsatisfactory, because the engine – which was probably originally designed for radiator cooling – will run too cold and the sea-water will eventually ruin the cylinder block and heads. Keel cooling is suitable for small boats operating in shallow weedy water, but the need for pipework external to the hull is a severe limitation. Heat exchanger cooling is the most common method, the seawater...

Bowman Le Refroidissement des Moteurs Marins Le refroidissement des moteurs marins – à essence ou à diesel – étudiés pour être refroidis par eau s’effectue de trois manières: par circulation directe, par échangeur de chaleur ou par la quille. Le refroidissement des cylindres et culasses par circulation directe d’eau de mer est déconseillé du fait qu’il tend à refroidir excessivement les moteurs prévus pour refroidissement par radiateur, qui marchent alors à une température trop basse, et que l’eau de mer finira par attaquer et endommager le bloc-cylindres et la culasse. Le refroidissement par...
