HAMMER HEAD DRIVE PLATES

More torsionally flexible than loop drive plates, usually have a smaller diameter element than our other designs but still retain the ability to be mounted either way round on the flywheel and rotate in either direction. Three stage stiffness with up to 9˚of deflection.

HIGH DEFLECTION DRIVE PLATES

Also known as wind up. Softer than other designs with a maximum deflection up to 30˚, slightly larger diameter element and can only be fitted to rotate in the standard direction of rotation (anti-clockwise looking at the flywheel) with the element facing the gearbox.

MARINE HEAT EXCHANGERS

A marine heat exchanger provides the cooling for a marine engine. In basic form it is a bundle of tubes where two cooling circuits meet and exchange the heat. This could be in the cooling circuit of an engine (marine heat exchanger), the oil circuit (oil cooler) or intake air (inter cooler). For cooling water circuits, where possible, look for a combined marine heat exchanger manifold. When these are not available, then a separate marine heat exchanger may be the answer. They are available in tubular form, or with an integral header tank, and models are available to suit engines of various outputs.

COMBINED HEAT EXCHANGERS / HEADER TANKS • Bowman heat exchanger header tanks are extremely universal • Can be engine or remote mounted to provide engine cooling and accessibility • Available in a range of sizes Replacement tubestacks available, see online at www.asap-supplies.com or contact our helpful sales team.

EXHAUST MANIFOLDS & MANICOOLERS

If you are looking for an engine for your boat, have you considered marinising one yourself? There are now many “bolt on” marinisation parts for a range of well known vehicle engines. Most can be easily converted for use in a boat. One important item we can help you with is the heat exchanger manifold. There are various options available from Bowman and Seaflow, including combined heat exchanger manifolds, keel cooled manicoolers and water cooled manifolds. Please contact us if the exhaust manifold you need is not listed and we will try to help you. Or for more information, please visit www.asap-supplies.com
