Canadian portage and gas smell

[ssaamm]

Just got back from a quick Canadian trip. I have a 90hp Yamaha 4-stroke. After going over the portages a couple of times with the motor trimmed way up and going up and down a pretty good slope, I noticed a gassy smell for a little while. I could see small gas slick in the water for a little bit as well. It was not the kind of smell my fishing partner was producing. Is it possilbe that the slant of the hill and the motor caused a little spillage or overflow somewhere in the engine? No change in engine performance. Any tips or thoughts would be appreciated. Thanks

It is hard for a carburetor float to do its job when the motor is trimmed. Because of the slant the float wont drop correctly and the needle will not restrict the fuel flow as well and you run a chance of the float bowl to overfill with gas. Probably is nothing to worry about.

Thanks for the reply.

I agree with Eurolarva... the bowls probably overflowed and some fuel ran out the front of the carb into the airbox, which drained into your lower cowl and should evaporate before too long, unless you clean it.
