Attempted to install the heating patch as per instructions but it did not stick to the rough as cast surface on the motor bracket. Called PROHEAT the manufacturer and their recommendation to Polaris was to install it on the bottom center of the crankcase for optium heat transfer. That would require attaching the patch to 100% of the engines prior to assembly as that surface is not accessible once the engine is in the chassis. The motor bracket didn't seem ideal for good heat transfer, so this is where and how I positioned the patch along with a couple of installation tips from PROHEAT. After removing the muffler as the first step from the original instructions, attach a lifting device to the RH side of the motor, remove the 1/2" allen head bolt, lift the motor about 1" (this was part of the procedure when the starter bushing fix was installed on the 06's), now the bottom RH cylinder portion of the crankcase with a smooth flat surface is accessible for the patch. A thin hand is prefered - you'll understand later.

RECOMMENDED TIPS: (1) repeat the process of blind wiping the surface using brake or carburator cleaner until really really clean, (2) before removing the adhesive protector and with the 120v cord facing front, do a trial positioning test to get a feel of working in a blind area (like the good ole days), (3) remove the adhesive protector, (4) this is important - plug in the patch for only 4 seconds to pre warm the patch, (5) position and press patch with fingers to the crankcase, (6) plug in for 4 additional seconds and repress the entire patch surface, (7) carefully route the power cord and plug avoiding exhaust pipe and turbo heat areas to a desireable location, (8) lower the engine, install the 1/2" bolt, replace the muffler and you are good to go.

This reads more dificult and technical than it really is, I believe the heat transfer will be siginificantly improved and located closer to PROHEAT's recommended surface. Good Luck!
