I have a 2003 HPDI 250. It blew a cylinder back in December. Yamaha installed a new 2007 powerhead under warranty, no questions asked. They also paid the dealer for a little bit if rewiring I wanted in the battery compartment.

In addition, it seemed to rev a bit higher than we wanted with my existing prop. The Yamaha rep came back twice to test 2 different props, and then gave me a brand new T prop, for free.

The service I received was outstanding. My last 5 motors have been Yamahas and I'm sticking with them.
