Re: eska 14208-a
I found this on brix enterprises web site, maybe the "a" stands for "Absolutely the last one"
"All Eska Outboards with model numbers 14205 and above where built in 1985 - 1986. Eska closed and stopped production in 1986.
Most of those motors used a 50:1 Oil Mix. Plugs used where J-12-Y with a gap of .030"
