As we all know, anything "marine" it is twice as expensive as its land counterpart. I ran across what maybe a great site for owners of vintage Yanmars such as my 1978 2QM15
I breezed through the site: http://www.hoyetractor.com
looking for a tractor of the same vintage as my 15 hp 2QM. Lo and behold, there is one. Problem is I can't get a fix on what the engine
might look like so I ask send them a request:
Hi, just stumbled across your site from a sailing forum. It's a great resource.
I have a sailboat with a 2QM15
, 2 cylinder 15 hp Yanmar
from 1978. I'm assuming this is a marine
version of a tractor engine
. Do you have any knowledge of what the equivalent might be?
Any assistance is greatly appreciated.
The response time was less than 20 mins but the response was less satisfying:
It is my understanding that the tractor, industrial, and marine
engines are all vastly different. I have never found anything that would interchange.
Finding this a bit hard to believe I say in return:
Ok, I can understand that the accessories such as water
pumps, and electrics would be different but it's hard to imagine a manufacturer making three different 15 hp blocks, heads, etc that would all use different internals such as pistons and rings.
Sounds like Yanmar
had enough resources to make extremely specialized engines from the ground up.
I'll suppose I will have to continue paying marine prices for valve cover gaskets, oil
filters, and the like.
Seriously? The 2QM series were built as marine engines only and share no parts
with other Yanmar models? I find that hard to believe.
