Greg is the most knowledgeable, hard working Yanmar Diesel engine mechanic in Orange County. While I have worked with a few of the Yanmar guys, I stopped using anyone other than him. His professionalism for showing up on time, never wasting time and complete availability for questions sets him apart. His wife Shellee is always helpful in arranging time, passing on information and most importantly, getting parts! They run a top quality shop. They are affordable, helpful and great people. You will not be disappointed. I own a 33 Rampage. 2250 hours. Go Irish! Dana Point.

It would be nice if the customer that gave us a 1 star review on Yelp 6 months ago, was actually one of our customers. Michael Ausman why would you give us a bad review when you are not even our customer. We have been in business for over 30 years & you dont stay in business that long if you are overcharging & doing poor mechanical work. How would you feel if someone said this to you about your business? (guitar bus.)

Would not help a retired guy on a fixed income. But a great place in SanTee did the work at a fair price.Advanced Diesal does good work. But they are over priced and to focused on making so much per person. So sad.Yanmar 2 cylinder injector pump rebuild 600.00Done SanTee for 225.00

Love these guys. Always have the parts I need to work on my Cummins QSBs. Shellee is always polite!

OVER PRICED AND POOR WORKMANSHIP

Theyre the best

Great service
