Perkins 4.108 Serpentine Belt Conversion Kit – $895

Say good-bye to belt dust, slipping belts, and thrown belts. Say good-bye also to trying to replace your belt in a seaway or picking one up at a NAPA on a Saturday afternoon in July. Foley now offers a six groove serpentine belt conversion kit for the Perkins 4.107/8. This kit is very complete and includes a full set of 3 anodized serpentine pulleys for the water pump, alternator, and crankshaft. These pulleys have been hardened to pass a Rockwell Hardness Test. This kit also includes a required serpentine belt. This will eliminate problems caused by a v-belt. You can drive a higher amp alternator (100 amps is about the very max you can drive with a single v-belt), raw water wash down pumps, refrigeration, etc. with this serpentine belt kit. Your cost is only $895.

Going to keep your boat for more than a year or two? You can also upgrade this basic 4.108 serpentine kit to our deluxe Perkins 4.108 serpentine belt kit. This deluxe kit includes all of the above plus a 105amp alternator and a new fresh water pump. Your cost is just $1495 for this complete kit.
