Just got my tohatsu sail pro back from the shop (under 5 years old so still under warranty for some things) because it decided to quit and backfire when put in gear and advancing the throttle. re start just fine but only runs just above idle and needed partial choke. Well had visions of major carb problems etc. Turns out was a sticky choke linkage. He lubed it and gave it a quick fuel system flush and all is better. I just did not see it on cursory exam. So for 124 bucks which included a new fuel filter and spark plug I am back in business. Gotta love these engines. They recommend changing the filter yearly regardless of time uses and same for plug. Sounds like a plan, and will lube the chock linkage too!
