The part was easy to find and was delivered on-time. The overall service was excellent.

Problem fixed: replace regulator/rectifier

After being left with a dead battery and realizing the engine was no longer recharging it during operation I understood the rectifier to be bad. I watched a youtube video and saw the swap was very easy. When I removed the old one it was melted in the back. I originally ordered a cheap replacement on Amazon and read both good and bad reviews of the cheap version. It lasted about as long as the bad reviews suggested and then I was no longer charging the battery again. I ordered the OEM version from Yamaha on the Crowley web site and installed it. The install for this part requires the removal of just 4 bolts and the lifting of the air filter from the front of the engine head...on this engine the part is connected with a cannon plug so you don't even have to worry about wiring. It takes 10 minutes to change. If you check the voltage across your battery terminals after the change, when the engine is running you should get more than when it is not running. If you aren't getting the charge then the voltage across the terminals drops with the engine running and you are draining your battery. Very simple.

I'm from a little town in Live Oak FL, I was searching hard to find a rectifier, and their price plus an extra fee I paid for two day air shipping was cheaper than any one I found online.I would highly recommend no matter where you live at in the states to check with Crowley marine first!!
