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.

Tesla ‘drops’ entry-level Model S. But was it ever going to be available?
Mon, 01 Apr 2013The 40kWh version of the Tesla Model S is being dropped by Tesla in the US, but we do wonder if Tesla ever had any intention of delivering it in the first place. Tesla’s big claim ahead of the arrival of the, very impressive, Model S – and a seemingly vital part of the US taxpayer funding Tesla to develop the Model S – was that they would deliver a car that cost under $50k, something the car industry thought impossible. But when the Model S was launched, Tesla did indeed have an entry-level model available with a 4okWh battery that was listed at $58,750 (taking it almost down to the $50k mark after the US taxpayer chipped in the EV bribe) so Elon Musk could, quite reasonably, claim Tesla had delivered.
Design and Technology at Siggraph 2008
Mon, 15 Sep 2008From 11-15 August over 28,000 artists, research scientists, developers, filmmakers, and academics from around the world gathered in Los Angeles for the 35th Siggraph Conference on Computer Graphics and Interactive Techniques. The Siggraph conference includes courses and technical paper presentations, new technologies demos, an art gallery, computer animation festival, and an exhibition by software and hardware vendors. While the New Tech Demos and the technical programs are focussed on technologies that designers will have to wait several years for, several automotive software and hardware suppliers announced new shipping products at Siggraph.
Tesco to sell Used Cars
Fri, 04 Feb 2011Tesco to sell Used cars Last time we looked, Tesco had broken the £1 billion a week sales barrier. It accounts for something daft like one pound in seven spent in the UK. And we worry about Murdoch?
