Mercruiser 1985-1997 4.3L V6 with V Belts *High Capacity for >90F Water Temp's* (Half system) (#5229-6)

This is a High Capacity system designed for 1985 thru 1997 Chevy based V6 engines 262 both sterndrive and inboard applications used in water temperatures above 90F. Block only. Engine block on fresh water system. Exhaust manifolds remain on raw water system.

Especially designed for the low capacity raw water pumps used on sterndrive engines. Will NOT fit most engines with high mounted alternators such as late model OMC engines and/or v-drives, or engines with a serpentine belt. Separate kits are available for those engines. Some engines have fuel line routing and fuel filter location that must be changed slightly. Heat exchanger is 4 1/8" x 23.5" long and fits within overall length, width, and height of most engine conversions. Heat exchanger extends from extreme starboard side of a normal exhaust manifold towards port side clearing most high mounted power steering pumps if any. See above illustration. Plastic expansion tank mounts either on front of heat exchanger or if space is limited on vertical surface next to engine.

Kit includes heat exchanger, heavy-duty translucent plastic expansion tank plus all other components necessary to complete conversion. Some components from engine are reused. Heat exchanger painted black. Brackets and other components painted black or zinc plated. Hose clamps all stainless. Shell and tube type. Special new high capacity design. All copper alloy construction made to the highest industry standards. Heavy-duty dual demountable clean out end covers. Zinc anode protection. Will maintain engine temperature in the 160-170 F range using 160 F thermostat, included in kit. System has capacity safety margin higher than industry standards. Heaters such as galley water heaters and cabin heaters are easily connected to the system by utilizing the cooling system bypass connections.

Very easy installation of approximately one hour, assuming new engine and normal accessibility. Allow additional time for filling and testing. Installation skills are not beyond those of most do-it-yourself boat owners. Complete illustrated installation instructions are included in kit. Ordinary hand tools used.
