    I believe you are correct Lew. I don't have any current plans to do anything with the mufflers. I will check to see if there is something additional that can go in line to augment but this is not a high priority for me.

    Same as mine, nothing needed to be done with mine. Although I keep a constant inspection of them every time I am in there

    Glendinning offers some quality controls to look at and Spurs does a good job with there line-cutters the Coast Guard uses them.

    Here is my order of preference for controls:
    1. Engine mfg. - after all, you are making changes to engine inputs, and that is the driver.
    2. Gearbox mfg. - a close second, they have some joystick/quickshift features that are nice to have.
    3. Aftermarket - only after exhausting the first two above, they have no stake between Engines and Gears and take on a middle man approach when things go wrong. Great opportunities for converting obsolete mechanical controls though.

    I went with the ZF Smart Command controls system. This is actually what CAT recommended and I ordered it thru CAT along with the engines and ZF gears. It actually does more than I need but had some nice features. I really like how everything is contained and selectable directly from the processors. There is no laptop and separate software required. I went to ZF's office and played with the demo system they had set up and really liked it.

    I haven't made a selection on line cutter yet.

    Have you ever been fouled by a pot line?

    When we managed boats, our divers told us if the cutters did not work perfect first pass (wrap), the foul was just worst and more dangerous for the divers hands and fingers.

    Please search YF for past threads on this subject.

    Making decent progress. All removals now complete. This was more challenging than expected. We found lots of abandoned cables and wires. Without knowing where they went or what they were for they had to be individually traced back to figure each one out. All have now been removed. Also, appears all the wiring harnesses were pre-made and pulled through chases going to bridge. You can't get inside the chase and there are a gazillion wire ties. Very difficult to remove individual cables. But the guys did a great job and got em all out.

    The engine room has been cleaned, primed and final finish coat of paint was applied last Friday. Now the new installations are beginning. They are starting by running all new fuel hoses from tanks to manifolds and cleaning this up. The installation was pretty hokey with unnecessary fittings, adapters , etc. We are cleaning this all up, with new fittings, hoses and using a cleaner, more direct routing.

    The 20kw Northern Lights gen is also going in. New foundation, exhaust and all new wiring and plumbing. J-box will be installed where you can actually get to it and open it if necessary in future.

    Some of the ZF controls cables and the CAT Common Ground cables have arrived and can start going in. The new water maker and 24v steering system shipped yesterday as well as new shafts, bearings and seals so that can all go in as soon as arrives.

    The goal is to have everything in and done, cables pulled, engine controls installed, etc before the C-18's arrive. The delivery of the C-18's is looking like it will be about 4-5 weeks later than originally planned but I think we will still be fine. Plenty to do before they get here.
