The good folks over at New England Marine Service in Rochester, MA sent us this brief video of our Serpentine Pulley Upgrade Kit, designed for the Universal M-25 engine, installed and running on the engine.
I have successfully mounted your pulleys on my M-25 Universal and they work great. Here are some pictures of how I attached your crankshaft pulley to my cast iron, counterbalanced crankshaft pulley.
Also, I sent along a link to a video of the engine running with the Balmar 75 amp alternator.
With all this information, if anyone else ever approaches Electromaax inquiring about converting an M-25 to a flat belt serpentine, now you know it can be done.
Thanks for collaborating with me on this custom pulley project!
