Hey All,
Recently purchased a 2009 tohatsu 9.8 four stroke. Ran great for about a month. Then it would die at about half throttle or less. I replaced everything fuel related from the tank to the cylinder including filters, pump, primer, carb plus spark plugs. That fixed it for 6 hours then it would run great and idle and slightly above but anything more and it would totally bog down and shake. I took it to a outboard mechanic in a boat yard and he said it was the rev limiter putting it into safe mode and preventing it from reving up. From a cold start it runs fine but after about a minute it bogs anything above idle. He cut the rev limiter wire and charged me 244$. Put it back on boat and instantly had the same problem. Now sometimes it dies even in idle. Took it back to mechanic and he said it was the switch that gets triggered when in gear telling the motor it’s ok to rev high. Tells me to replace the switch myself, doesn’t work. Told mechanic and he said have you tried googling the problem. top notch mechanic ......... I have a great short video of the problem in action but the file type won’t upload here. If you’re interested or think you can solve it and want to see the video please pm me here and send an email or phone number and I’ll send it right away. Any help would be extremely appreciated. Or just text or email me. 8087251072 [email protected].
