I'm about to get a 115 hp Evinrude v-4 from mid 70's vintatge. It had
w new power head installed about 10 yrs ago and hasn't run but a
season. I'm getting the motor cheap, I figure it might be worth
stuffing back for my never ending quest for a 28 (+/-) ft. Pontoon
boat.

OK, so asking those with experience with these motors, which oil
should be recommended?

regular type two-cycle marine? Synthetic blend? or straight Synthetic?

I realize engine oils and lubricants have vastly improved over the
years, especially since this engine was born, and so I'm open for
suggestions. I've *heard* that synthetics can be too thin and isn't
recommended on older engines that have wider tolorances. But I don't
know, thats why I'm asking.

Thoughts on oils and brands?

THANKS!
Tim
