      December 21, 2020 at 1:14 pm I am installing 2 VDO Viewline Pyrometers (A2C 5351 0907S also know as A2C 5951 2332) for my Yanmar 6LY2A-STC engines. VDO sells a kit for it, but it very expensive. https://www.vdo-gauges.com/instruments-displays-and-clusters/by-type/pyrometer/viewline-onyx-1600-deg-f-pyrometer-12v-with-vdo-sender.html What I need is the Theromocouples and some extension wire (about 20 Feet for each engine). I saw the SMX EGT Pyro thermocouple and was wondering…

    • exhaust support stanchions

      This topic has 2 replies, has 2 voices, and was last updated byBrian Fitzpatrick 3 years ago

      November 11, 2020 at 7:35 pm where can the stanchions be anchored? the pipe has flanges on the ell’s and the mixer. the first flex point is after the mixer. The plan is to put a support stanchion on the mixer. on one engine it will be anchored on the transmission. the other engine pipes run aft of the transmission. I am looking for a point to anchor it on a stringer. There is my question: if I anchor it at the stringer, will engine torque / flex put stress on the flan…

      November 12, 2020 at 7:59 pm Thank you. The attached photo (img 3413) is close to the way the final configuration will be for the starboard engine. I need to rise the mixer 5 more inches to bring it to the level to meet the 6″ pipe. I have 2 questions: 1. This is a heavy cast iron mixer. Will heavy wall pipe with rubber hose double clamped over it support the weight? Or do I need to make a stronger support? Like welded angle iron? 2. Once I raise the mixer to meet th…

    • cast iron to stainless exhaust components

      This topic has 2 replies, has 2 voices, and was last updated byBrian Fitzpatrick 3 years ago

      August 23, 2020 at 7:09 am What is the opinion of adding a 316 stainless steel exhaust mixer elbow to an existing cast iron riser? The attached photo is a Yanmar 6LY2AM-STPC installation I have. The mixing elbow has to be replaced because of it’s design. This is the way we purchased it, and I need to correct it. I can get a stainless mixing elbow made locally that will put the injection on the down hill side of the high point to prevent flooding the turbo when it l…

      August 23, 2020 at 8:06 am Thank you. I was planning on salvaging the cast iron bend out (dry) of the turbo and adding a stainless riser & mixing elbow with more rise, and drain downhill in the exhaust exit if (when) it leaks internally. I read Tony’s Tips on exhaust systems and recognize this is a dangerous design as it exists. I want to change that. Is there an issue with electrolysis between cast iron and 316 stainless? Would the different coefficients of ex…

      December 25, 2019 at 10:51 am I’m replacing the Tachometers in my Cruisers Yachts 460 Express with VDO Viewline Tachs. I think the flywheel on the engines have 127 teeth. I need to set the pulses per revolution on the tachs. Is it 127? instructions are attached. Thank you
