"The LL actually stands for lots of lead.Much more than 80/87.Besides the only av gas left is 100LL".
Lead never hurt an outboard.
In the 60's I was stationed in PR
, and since av gas was "free" (PURPLE !! 115/145) an old P2 alcohol tank held enough to run my 13ft Boston Whaler from PR
to St Thomas and back.
Kept my boat in ST T and trolled the tourist babes for recreation.
Then were the days , before AIDS, STD and the rest!!
