Our 40HP Evinrude motor started jerking the boat periodically, then will ride smooth for a few minites,then start jerking again like it has good gas then no gas. You can feel it jerking in the control throttles. Is this bad gas or do we have a serious problem? Could it be in the gear box? It did this several times last summer then we have had no problems till this year starting about 3 weeks ago. Your help is appreciated. [/email}lanescrib@aol.com[/EMAIL]
