470 conversion kit MerCruiser 3" to 4" exchanger
This kit converts 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 and has the necessary hardware, and the fittings are placed where they would be on the 3". This is the very best way to handle 470 cooling problems, and is the top-of-the-line quality.
