Query: Spend the extra money and buy the Clymer Service Manual

Very disappointed, this manual only covers the powerhead in detail. There is not even a section for the intermediate housing, and the lower unit section is just several pages long and covers water pump replacement only. I have a 2000 model year Merc 200 and the water pump info and illustrations were for earlier models, so even that wasn't helpful.I've had several Clymer manuals for the various engines I've owned over the years, they cover everything.
