      November 4, 2016 at 12:07 pm Welcome to the site…………….  You will find nothing but honest help here proven over decades & 1000’s of hours of learning diesel engines as to what works, and more importantly, what doesn’t work. Where I believe this site really excels is dealing with the last two generations of high performance diesels (smaller displacement light iron diesels that produce 60-80+ HP per liter) and are really the reaso…

      April 16, 2018 at 3:16 pm I own a 2005 Searay 39 Dancer with cummins 5.9 qsb’s. The starboard fuel cooler let go & racor water alarm goes off. I have owned the boat since new. 1st cooler let go in 2011 at 600 hours. Replaced cooler ran ok for 2 years (200 hrs) then let go again. I have replaced every 2 years since. All my zincs on starboard side( lower after cooler, trim tabs, water strainer pick ups for starboard engine, a/c all only last 3 months. The starboa…

      Reply #5 April 17, 2018 at 4:21 am I was having trouble with exessive zinc consumption and had a galvanic survey performed. The system was entirely intact and we were puzzled. We then did a check of the power post on the dock. What we found is the power post was sending .005 volts back to the boat, causing all my issues. We installed a galvanic isolator and zinc consumption became consistent with my neighbors.

    • Installing SMX1730 pump

      This topic has 4 replies, has 3 voices, and was last updated by Roger Howell 1 week ago

      April 8, 2018 at 10:52 am Hi, I have ordered and installed a SMX1730 raw water pump on my new to me 2001 Cummins 6 cta 8.3 450. Is the pump bi directional, or is there a specific inlet and outlet port? Hopefully I have not installed it upside down. Still a while in Maine before I can run the engine to check water flow without rewinterizing. Thanks for your help. Roger Roger

    • Yanmar 4cyl vs Yanmar 6cyl

      April 5, 2018 at 11:18 am In general, for my search for a boat I have searched only for those with Cummins Engines. Parts are cheap and available, and mechanics are readily available to work on them. However, there are some boats that I might consider that come up with the Yanmar engines such as the 6LPAs and the 240HP 4 cyl. I have eliminated the 6 cyl from consideration for such things as Valve seal issues and more stringent maintenance requirements. But how about the…

      March 28, 2018 at 10:34 am We are purchasing a 1998 BL 4788 with an 8KW Westerbeke in a sound shield. The sound shield has the black plastic latches and looks to be of better quality/fit than the ones I’ve seen with metal latches. I’ve read some posts on the Bayliner Owners Club forum (they REALLY like sbmar!) that reference an exhaust modification and since sbmar is “the” place for marine exhaust work it was recommended that I post here for advice.…

      June 19, 2017 at 5:18 pm Has anyone had a issue with a 9KW Onan Rotor? If so did find the part? My local Cummings/Onan service shop say they discontinued the part. Not sure if they make one yet under a different part number, but it’s not looking promising. Does anyone know if the engine, which is a 3 cylinder Kubota can be adapted to a different Stator/rotar assembly? Any help would be appreciated.

      February 13, 2018 at 12:56 pm This sounds suspect but I figured I’d throw it out there for comment…. The theory is to plumb a cross connect fuel line between last chance filters on a dual engine setup so that an operating engine can supply pressurized fuel to prime the other engine. Simple idea? Maybe, but I wonder if it’s introducing a liability that’s not needed. I know there are primer bulb setups that do a safe and reliable job. And if you know what your doi…
