I'm about to pull a compression test. Probably will find ring damage to bottom cylinder. Experienced SAFE mode shut down. Heard some rattling in the cylinder. Will try to isolate the problem. Most of the repair shops in my area are booked. It appears that a diagnostic program for my laptop is available. No doubt the program will be needed. My thoughts are "get a new power head" and address the powerhead, injectors, lower unit while the motor is down. I hate to put money into a motor if it requires a lot of dealer support. Switch brands?
