Just a heads up. I've done quite a bit of research
regarding the U exhaust elbow
for Yanmars. While stainless steel
versions of the same thickness can be found on eBay for $155.00, adapter and hose fitting included, stainless is not recommended for normally aspirated Yanmars. This is because the stainless is constantly exposed to salt water
and most importantly high heat. The consequence is the stainless will be affected by severe pitting. However, stainless can be used in turbo-charged engines because there is minimal exposure to salt water
Now, the good news. These engines supposedly all use the same U elbow.
"U" style 2" For Engines;
, 2GM20F, 3GM30F, 2GM20-YEU,
3GM30-YEU, 3GM30F-YEU, 2YM15, 3YM20,
, 3HM, 3HMF, 3HM35, 3HM35F
Part number 124070-13521 is specified for my 2YM15. The cost from my local Yanmar service
center is $188 + tax. As I considered my choices I realized 104214-13521specified for older Yanmars had the same suffix as the part number specified for my engine
but is available for $112 and no tax.
To make a long story short, I learned both are from the same casting mould, made of the same material and the only difference is the hose fittings!
So, I ordered two 104214-13521 - no tax applied - and spent marginally more than it costs for one 124070-13521. Don't believe it? Here's proof.
