OK, I finally snapped a few pictures of my '84. I'll try to get a few more next time I'm on the water. As I said earlier, this was a tournament boat in the NW back in the 80's. It was used mostly for trick skiing. I am the second owner, but have had it for ~20 years.
It sat for almost TEN YEARS in my garage without any use (through two houses)! I refused to sell it.
I replaced distributor/wires/springs/plugs/points ... rebuilt the (Sherwood) pump, manually checked the timing and generally worked it over for a few weeks last year.
It fired right up.
FWIW, I was going add electronic ignition... I bought a set of $5 advance springs instead.
