I bought an 06 G3 with a 50hp Yamaha 2-stroke. It idles at a high rpm (the tach doesn’t work righ some I’m not sure on RPM). When I put it in gear idles rough. I bump up the throttle just a bit to around 5 mph and no issues, the RPMs sound better. WOT it runs good I’ve had it up to 35-36mph with me and my 8 year old son which I’m happy with. It just seems like it doesn’t like low RPMs. Any ideas?
