The models that came after mine could be retrofitted with a new
carburator part (jet??)that allowed you to use a 25:1 ratio.



I've always been convinced the reason "they" want you to run so thin a
lube oil is to hit the target of the powerhead wearing out 3 days after
the end of the warranty period.

Case in point was a 1997 Sea Rayder F16XR2 jetboat I owned. After seeing
several recalls of the cheap plastic oil injection system that failed a
lot blowing powerheads for lack of oil, even at 50:1, I removed all that
and used 25:1 mixture for the rest of the time I owned it, long over 1000
hours. The present owner has another thousand hours on it mixing just
that way and the engine is still tight, starts instantly and turns as
many RPM as the day it was purchased. Unfortunately, for him, his
girlfriend, a beautiful Eurasian in her 20's now, would always ride with
me in it to the beach. He, stupidly, scared her and she doesn't like to
ride around with him in it, now....(c;

I don't believe you can overoil a 2-stroker. It's just a matter of what
you find the acceptable life of it to be. Since 1954 sounds like you'd
be better off not screwing around with a mixture that works great for 50
years!
