The Anzani is a decendent of the Oliver outboard motor.
There is an Oliver site that may have some info.
Do a search using oliver outboard.I believe the water outlet will be midway up the leg.The intake will be below
the antivent plate. Should be an obvious opening with a screen or slots or holes.While I believe Anzani is still in busuiness I think outboard production has stopped.
On one gearcase diagram I looked at, it looks like the water comes in just in front of the propeller. On another one, there was an intake screen above the propeller.
