Hi,
I took our pontoon boat with a 90hp Merc. 2 stroke outboard out for it's first Spring run and it kept dying under load and was hard to re-start. I assumed there was water in the gas as the tank was left 1/2 full, so I added drygas and filled balance of tank with fresh gas. It started a little better and idles to very low RPM in gear OK, but when I call for any more speed/power, it just stalls/bogs down; re-starts fine. What's more likely, dirty carburetor/chokes or fouled plugs? I'm not familiar with 2-stroke outboards, but am familiar with 2-stroke snowmobiles; that's why it seems like either fouled plugs or dirty/sticking chokes - however, neither ever seem to stall/kill the motor in a snowmobile. Or does it sound more like a fuel filter/high speed jets? Please help!! Thanks!!! Nelson
