I have a 2006 225ho and have zero problems, except for those that was self imposed.
Recommend having the oil setting on XD-50 and run XD100. And you should be ok. Great motor, I had a Yamaha and traded for the E-tec and never looked back...
Are there different settings on the motor for the type of oil to run? I'm a little confused. What is the differece between XD50 and XD100?
