Boat outboard guys

I Just got myself a mint condition, 1986 Evinrude 28hp special. On the motor, it has a little sticker of 100/1 mix. Im worried about blowing it up. I have been doing 50/1. What do you know about this? Thanks

I wouldn't ever go less than 50/1, and even then I would run syn. If your going to run dino, 32/1 is best IMHO. Love the Evinrudes! Mines a 1980 or so 12 hp. (aluminum fishing boat)

iv run 100:1 on countless Outboards, without problems, Even on old 2 strokes, the run richer as the wear out, i wouldn't be to concerned with it IMO,,, a 86 probably needs a good rebuild anyways...

i would run what they recommend, and having more oil CAN blow your motor too because it lessens the gas which cools the piston

OMC only tried that for a couple of years then went back to 50/1. I would only run 50/1 in that motor since it is still on old design. Back in the day an OMC rep told us to just peel those stickers off.

New problem, My top cylinder has no spark. I have replaced the coil, Checked fuses, new plugs. Cant find any broken/unconnected wires. any ideas where to go next?

More than likely it's time for a power pack. It's the black box to the left of the head when you are looking at the back of the motor. There is a company called CDI that makes probably the most economical replacements. Believe it or not one of the quick tests to see if that is it is to rap it with a hammer with the engine running and it will usually pick the dead cylinder up and then drop it again. If you want the meter specs I can get you them tomorrow.

Put a new pack in and run it not thicker than 75:1.

50:1 is too rich.

Good luck

Good luck+1......Make sure you keep a paper clip w/you(I hang it off the motor handle w/ a rubber band) to keep the water pump jet hole at the rear of engine clean.(keep an eye on that steam of water!) I locked up that same motor when that hole clogged....and change the water pump too! (impeller wheel $10)..Beets

I found out, after 4 hours of tinkering, I have beautyfull spark. When I take the top plug out, she starts and runs. when I take just the bottom plug out, no running. When I have both in, no running. If I hold the choke open, with both plugs in, she runs but not well. Im trying to find a diagram online so I can look for missing pieces. Maybe someone stole from me!!! THanks all for the replys.

Check your reeds. Does it spit out the carb when it runs? What's the compression?
