Turbo maintenance advice needed.

6 years ago September 22, 2017 at 5:11 pm Hello all, I’ve got QSM11’s, 660 hp. 1276 hours. I’m doing my routine inspection of the engines and found that both air cleaners were a little dirty. Not bad since the last cleaning and re-oiling was done 260 hours ago (18 months). I normally check the air cleaners and turbos for wear every 100 or so hours. During my inspection I noticed a small amount of soot on the end of the blades of the turbos. I’ve cleaned, oiled…

7 years ago March 3, 2017 at 8:15 pm Hi, I changed my current SmartCraft 5000 (2003 version 1.0) to a NOS 2006, version 3.3. After replacing the display I noticed it offered more information like manifold temp, load, gear temp. My question is this: I didn’t have this information on my old SmartCraft so apparently I don’t have the sensors, can I install /adapt the sensors and wiring to the new SmartCraft display or am I stuck with the information I had on the old display…

ZF 325 IV shift question
This topic has 3 replies, has 2 voices, and was last updated by
7 years ago December 9, 2016 at 7:02 pm Hi Tony, Hi Rob, I need to find written instructions regarding the “manual” shifting of my ZF 325IV gears. If you can point me in the right direction, I’d appreciate it. I’ve searched the internet, you tube, etc, etc. Can’t find anything, but I know it can be done. The reason I need to know is because a friend of mine was running about 100 miles offshore when his captain was not able to shift his port side ZF gear i…
