Sorry I haven't responded earlier. I have other projects on the go.
Like I said before it's highly unlikely you'll find an "oweners manual" for your
power boat like the owners manual you get with your car.
Boats just aren't produced in large enough numbers for builders to invest the many thousands of dollars in the production of a dedicated owners manual. Higher volume
boats possibly such as the Bayliners, Doral's etc. It's different with cars when a production run int he 10's of thousands of identical vehicles dictates the economincs in producing a generic manual for that particular model of car. Boats with production #'s in the 100's it's highly unlikely that a
builder would make that kind of investment.
What you'll usually find, this has been my experience, you'll get a binder or satchel with all the mfgr's
documentation on each piece of
equipment installed on a boat. Such as the OEM
maintenance manual for your
engine and outdrive. For older boats that have passed through a few owners, such as mine, I had to re-assemble my package myself and it took a few years and plenty of
research on the
Internet but I did finanlly find the engine/outdrive
manuals including the shop
service manuals, exploded
parts diagrams & listings, manuals for the
head & pumps etc. I've also replaced a lot of the systems and put the new
documentation into the binder that'll go with the boat when it's
sold.
So you might be looking for the "Holy Grail" for Thompson boats but as you mentioned you've contacted them for assistance. IMHO that's your only hope if one even exists.
