I have heard and read (in earlier postings) straight 30W oil is good to use,
and others recommend 25W40. I have an 1986 350 I/O and have been using the
25W40 for several years, but am now wondering if I can or should use
straight 30W oil? Did they even have 25W40 back in 86, or is this an
improvement over alternatives?

Since most people only use their boat during the warmer months, straight
30W is normally recommended.
