      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…

      February 15, 2018 at 8:15 pm I have a job that the owner of a older 38 Bertram wants the lower steering lines/hoses replaced. Its a capilano steering system. I guess now its seastar solutions. There specs say copper or 1000 psi equivalent hydraulic hose. Copper is going to be tough as its a old boat and ots just not that easy to run the lines with bends. Looking for ideas on the hydraulic hose to use. Stainless jic in some areas like the rudder most likely. Very pricey th…

      Reply #1 February 16, 2018 at 4:36 am Esa puede ser una solución rápida para ayudar a resolver un problema de aumento de temperatura, pero esa no es la manera correcta de reparar los componentes de agua de mar. Nada reemplaza la eliminación de los refrigeradores para una limpieza adecuada y pruebas de presión. Y eso definitivamente no hará nada para extender la vida de sus posenfriadores.

    • Cross connecting fuel supplies

      This topic has 2 replies, has 2 voices, and was last updated by Philip 1 week ago

      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…

      February 8, 2018 at 1:19 pm I have a pair of QSM 11s in a 2008, 50′ Altima trawler. I have owned the boat for 3 months and recently the starboard engine will shut down for no obvious reason. I am in south Florida with mild temps. The engine runs perfectly and suddenly turns off ( usually after operating for 30 minutes to an hour) as if I had pressed the shutdown switch and turned off the ignition. When this occurs the ignition to the starboard engine is dead i.e. no…

Now that I have it out should I just pressure test it, paint and reinstall if all is ok or should I just replace it with a new one? What’s the life span of these anyway? TIA Jeff
