170 470 conversion kit MerCruiser 3" to 4" exchanger
This kit converts 170 and 470 MC 1/0 engines that presently have 3" exchangers (77319) over to our high capacity 4" exchanger. This exchanger is designed specifically for this kit. This is the very best way to handle 470 cooling problems, and is the top-of-the-line quality. This company supplied MC with these for many years! We reserve the right to ship a like brand at no substitute in quality or increase in price if there are supply problems with one or the other. You must buy short length of hose not supplied with kit. (You should really change all your hoses when changing any heat exchanger)
