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.

Mercruiser Rotor
by John from Mashpee, Massachusetts on December 11, 2015
These are pesky little buggers to get off. Always good to have an extra on hand. At this price quality, there's no excuse not to. Perfect fit works great!

Excellent.
by William from Niskayuna, New York on August 19, 2012
I had a heck of a time getting the old rotor off, but once I was able to tap it loose, this went on perfectly and worked great.
