I would like opinions from you boat wizards familiar with Zen and
outboards.

My Nissan 3.5 drives my small Portaboat around nicely but its user
manual and the label on the fuel tank disagree. The manual tells me to
use 25:1 fuelil ratio and the label says 50:1. I've been running 25:1
because it's what I saw first. I don't notice significant smoke and
haven't had it long enough to foul the plug yet.

Any ideas on which way is best or whether this is even a subject worth
discussing? Thanks.

I just looked at the on-line owners manual on Nissan's website
(www.nissanmarine.com) and the 25:1 is for the Break-In period ONLY. After that
it goes to 50:1. There's a couple of other articles on their "Tech Talk"
section that confirm this as well. Good info there, check it out.
