The original Yanmar product is made from thin .060 stainless tubing and is welded.  Please see the picture of the sectioned parts where the brand new Yanmars weld penetration is less than desirable.

HDI Marine elbows are all precision investment cast 316 stainless. 

Our flange thickness is 50% thicker  Yanmar's  .220 / 5.7mm  

 HDI Marine's .320  / 8.2mm

Our tube thickness is 60% thicker   Yanmar's  .062 / 1.5mm    

HDI Marine's .097 / 2.5mm

 

Our design using thicker tubing does not constrict the exhaust.  We maintained the OEM inside diameter and increased the outside diameter to compensate for the thicker wall tubes.  This allows the same volume of water and exhaust gases to escape.  We narrowed the outside diameter back down after the exhaust tube ends to maintain the proper hose size.

 

I started making these stainless steel mixing elbows when my Yanmar iron elbow failed me.  I was shocked at the cost and the fact they were still cast iron.  As most of us know; salt water, heat & cast iron don't work well together. When I realized I could fix this, not only for me but for other boat owners around the world, I couldn’t help but try.

 

 I am a manufacturing engineer and have specialized in castings for over 25 years. These parts are guaranteed for 2 years but should last a lifetime. I installed the first one I made into my 4LH-STE in 2005. It still looks new inside and out. The product line has grown only from people asking me to make products for their engine, after stumbling upon another elbow for a different model.  I take a lot of pride in my products; you will see and feel the quality when you receive it.

 

Please note OEM's have made different mixing elbows for the same engines.  Example: Yanmar has equipped the 4LH-STE with 5 different elbows to accommodate changes in horsepower and engine mounting location in relationship to waterline.  They also change their part numbers often.   My experience is that comparing a picture is always worth more than paying to ship it back.

Driverless 'pods' to hit Milton Keynes

Mon, 11 Nov 2013

DRIVERLESS cars will transport people through the streets of a British town in a £1.5 million project aimed at boosting green technology. From 2015 an initial batch of 20 driver-operated "pods", which will be able to carry two people, will be run on designated pathways separated from pedestrians in Milton Keynes.

Hyundai i40 Saloon - Europe's own i40 saloon gets launched at Barcelona It’s all been topsy-turvy, the launch of the Hyundai i40.
