Engine Manual
First Impressions
The Yanmar engine is smaller and about 200 pounds lighter than the old W60. It comes with a single pulley and belt that drives a water
pump and an 80A alternator with an internal fixed voltage regulator. The turbo unit is mounted above the transmission and includes an
air cleaner. This should help reduce engine noise. The fuel filter includes a manual lift pump. It is located in an awkward position on
the right back corner of the engine.

The engine comes with a secondary fuel filter and a coolant reservoir tank. The Racor unit from my old engine is superior and will be
used instead. A plastic pouch with tools for the engine is also provided. This would have been a nice touch if the tools were usable. In
my opinion, they are junk; a few cheap open-end wrenches. They would be better off omitting the junk.

A plastic pouch holds the engine paperwork. This includes a detailed checklist that must be performed before the warranty can be
activated. The instruction manual that comes with the engine is brief. It has safety andbasic operation information, but lacks specifics
regarding installation or maintenance. The troubleshooting guide is fairly useless. It directs the reader to contact their local distributor
for most problems. One nice thing about the manual is that it is provided in electronic form as a pdf file. It would have been nice if
the file were available as a download before the purchase. This would have provided some information that I had to dig for when
selecting an engine.

Yanmar has a very nice web site with lots of information that is missing from the owner's manual. It would be nice if they had this in a
printer friendly version so that you don't have to play "where's Waldo" with their web pages.

There is additional information at the Yanmar web site regarding break in procedure, coolant selection, and some installation
information. I was surprised to see a strong warning about idling the engine during the break-in period. They indicate that the engine
must be run under load or the cylinders will glaze. They specify that the engine must be run under load between 2000 RPM and 3000
RPM at varying speeds for the first five hours. For the next 45 hours, they say that you can do what you like as long as you don't spend
a lot of time idling. My average annual running time is about 100 hrs/yr. This means that I'll be unable to sit at anchor and charge my
batteries. I'll have to take the boat out for short trips each day for the first few weeks.
