Had the boat out today and the motor started acting up. '89 Merc 115 oil injected. When I first tried to give it full throttle it would only rev to about 1,500 rpm. I slipped it in neutral and revved it a couple of times and it seemed ok, so tried again and it did just fine. Got about half a mile down the lake and it did it again. Idled down and then it took full throttle ok again. Ran ok back to the dock until I idled down in the no wake zone then it sounded like it was missing on one or possibly two cylinders. Did this once before several days ago, but I thought it might have picked up water or a bit of crud in the gas. I used stabilizer over the winter and have re filled the tank recently with fresh fuel
Had new tuneup last Summer and has less than 10 hours since
Any ideas appreciated
