yeahjohn, thanks for those tips.
I also found Don's useful remarks at
from

" IGNITION SYSTEM: Install a permanent back-up ignition switch in the engine compartment to connect the big battery terminal on the starter solenoid directly to the primary terminal of the coil to be used any time a failure of the ignition system is suspected."
I was thinking that would have to be a heavy duty switch! Which side of the coil is the 'primary terminal'? Don's advice regarding wiring harness is well taken, though I cringe. Mine is original and very well made, by an electrical engineer, but its very complex and the widow of the builder dumped all his notes, spares, etc, before I found the boat.
Xmas list item 1 - wiring diagram.
"EXHAUST SYSTEM: Install a 1/8” pipe tap in your exhaust manifold outlet flange to enable measuring exhaust system back pressure."
I doubt I've got exhaust blockage, but its always possible - yipee, another engine hole adventure
