Since the old pages - I have not done anything much new on the engine. Now I have run more than 1200 miles cruising - I have gotten to know it a little better. I still don't understand it - ok I know the tech stuff and most of its basic internals - ( short of how the governor actually works ! ) - but these engines can be fickle at times.
So I have brought together the recent pages on the engine. They may be of use to some.
Shop Manuals - these are the real Workshop manuals - not the service manuals.
The full 2002 Workshop Manual - ( big download ) 'can't find it ' - its somewhere ! ( If you need a copy I have one )
When you visit this page now they have limited the downloads per session - still free. Click on the Yanmar link on the left list.
There are many mistakes in the later manual ( I have that as a copy I bought from Yanmar ) - and some sections are far from clear. The earlier version had a compete section devoted to single cylinder models. The later bunched all three together.
