    The offer to purchase was accepted today contingent on the satisfactory completion of the general marine survey, the mechanical survey and sea trial. I expect that the surveys will occur sometime the last week of this month.
    Trawler information:
    The vessel was built in Nova Scotia, Canada.
    Single engine: Cummins 6BT 5.9 M/ 220 HP/Serial # 45995943
    Total engine hours: 585
    Vessel location: Anacortes, WA
    Use: recreational
    Transmission model/ratio: awaiting information from seller’s broker
    I would appreciate any information about this vessel and engine. The photos are attached below.
    Thanks for the advice.

    Saltwater use

    To my knowledge, the vessel has been used in saltwater since launch.
    Thanks Tony

    Make sure she get’s a true cold start. No block heaters, pan heaters, engine room space heaters, etc and she sits overnight – cold to the touch. Based on your location this will be a truly cold start so she may smoke a bit, and continue to smoke somewhat until she’s pulled out of the slip and gets some load on her to get cylinder temps up.

    And, of course, once warmed up and underway, check for black smoke and be sure the engine is photo-tached for RPM accuracy and brought up to WOT to check for proper engine loading (propping). This should be done after 100% verifying with your own eyes that the bottom and running gear are 100% clean so if she comes up short on RPM’s there are no “excuses.” Watch the engine temp as she comes up to and runs at WOT, this will give you some sign as to any blockages or deferred maintenance.

    A clean looking engine, a non-planning vessel and no seawater cooled aftercooler – you’re off to a good start, good luck!

    Check out the exhaust system

    Read Tony’s articles on marine exhaust, maybe post some photos of the exhaust set up so some of the knowledgeable people on this forum can comment on that. I recently replaced the original OEM exhaust on my new to me boat, just before it caused some real damage. It had just started to leak from corrosion causing the exhaust hose to overheat. I caught it due to an exhaust alarm I had recently installed. It was the dreaded “doomed to fail” exhaust that when it starts to leak (and maybe even before) would put sea water into the turbo and even into the exhaust manifold allowing access to the engine itself. This is also part of the salt water exposed parts Tony was talking about. My engine is the 6BTA M3 330 hp.
    Good luck on your decision, and you have come to the right place for good info related to these engines. Tony (and others on this site) are the best!
    Regards,
    Tom

    I will tell you this.. The engine left the factory as a world class engine that has set a reliability standard that is in a class of its own, & any other engine produced today in this class only wishes it could approach..

    Very simple in operation and maintenance as to maintaining it.. The only part of the engine that might be considered “weak”, would be the seawater components as these are all subject to “Marine Age”, and at this point, you are 16+ years into that.. IMO, the components that are in seawater need to be replaced proactively, regardless on engine hours. Has the vessel been in seawater since new?

    BTW, no survey will touch this as a possible or REAL concern.

    Tony
