I just did the job for Brad Schoenwald. I first scanned the computers for codes, then did a compression test on warm engines with wide-open throttles.
Entire job took 10 hours and the springs were about $500.00.

Yeah, it's closer to riding a car in 3rd gear at 4000 rpms up hill for 200 hrs.

Thanks Mr. Cozzi
If it ever warms up around here I am looking forward to our shake-down cruise.

Brad is a great helper and if he wasn't there 10 hours would never be enough to do it like we did.

Sorry Ed-We ran Sunday--I know, it was wicked cold and the wind was about 20-25 kts so I busted out my old Alaska wear. My neighbor still thinks I'm nuts but I didn't want to wait and with the wind out of the NW it gave us a decent lee close to the beach. "Tubbs" and I ran out of Port Everglades and everything is good, it was a little rough but we were able to run WOT for a bit and got great numbers for the conditions.

Thanks again and call me anytime so I can get you back out...
