Hello,
I have an outboard 2-stroke engine Evinrude (y. 1997, BE70TLEUM).
I must say it's a good old one, running so far without any issues but lately I'm noticing this.
When my boat is in water and I set with remote control for example 3000 rpm but then after a few seconds it starts to increase revs by itself. It goes up almost up to 3800 rpm. Sometimes it can be opposite - rpms are decreasing down to 2000 rpm. No matter what - I am struggling up and down with remote stick to find a safe spot where revs might be stable. And also it doesn't matter if engine is "cold" or "hot".
What do you thing is causing this? Should I focus on fuel pump (it is VRO), carburetor, etc?
Thank You.
