Fit perfectly - fast delivery
by Scott from St Charles, Missouri on June 23, 2014
This item arrived very quickly and was exactly the part I needed. Received a dist cap, plugs, and wires with the order as well. Before installation, I cranked for over 30 minutes, trying everything to get my boat started. 30 minute install and the boat turned over the very first time. Great advice, fast service, and good prices.

rotor review
by George from Ottawa, Ontario on July 06, 2010
Got this rotor, and the first thing I noticed was that the electrical metal contact was a solid 1/8 inch thick cooper bar at the bottom of the rotor. This seems to work as my boat now idles strongly even at lower rpm.
