Default Replace or Repair 1969 40hp Johnson Repair Question

I have a 1969 40hp Johnson that has been sitting for many years out of
the water. It is a relative's boat and when it was parked it ran fine.
It was parked due to the throttle cable breaking. The boat is 70
Glastron and in good condition but I am wondering what my first step
should be on getting on the motor up and running. Is there a good book
or manual anyone can recommend on buying? I work on my cars replacing
waterpumps, starts, etc so I can follow a manual on taking parts off
and replacing them. Also have the option of buying a 55hp Chrysler for
$200. The Ad says
i`bought`engine`2`years`ago`and`it`ran`when`i`got` it`i`hook`to`batt`every`once`and`a`while`and`turn` it`over`very`good`comp`and`spark.

Thanks

The cable is available.

The amount of work needed otherwise could range from none, to a lot.

I would change the water pump impeller(part # 377230) at minimum, then
do a complete ignition tune-up including points(2 sets - part # 580148),
condensers(2 - part # 581419), & testing & leak-testing the coils(2 -
part # 582995 or 584477). All parts are readily available.

The fuel system should be cleaned.

Perform all routine maintenance - lower unit lube change & pressure check.

Then you should be ready to launch.

The Chrysler is somewhat of an orphan now since Brunswick has shuttered
all Chrysler/Force production , but thanks to the Internet, parts can
still be sourced to some degree.
