    Default shaking bad once warm

    new to the forum thx for having me. so my 50 hp starts right up idles great, after a few mins out on the water it's shakes really bad so I throttle down for a few mins and it will let me run down the river for a few more mins before it does it again. It never dies and idles great during that. thx in advance for the help

    Yam has produced hundreds of 50hp models. Which one do you have?

    Oh boy, I don't know much about those jet drives. Go to www.yamahaoutboardparts.com and register as a member. That forum is solely for yamaha engines and there are a number of yamaha marine mechanics who are members that can help you out. When you make your initial post, be sure to include the complete year and model number of the engine.

    Sound like it is starving for fuel, try pumping the primer bulb the moment it happens, could just be a dirty filter
