The great help I received from you all helped me to get my 79 Evinrude 25hp running like a champ. Now my brother wants me to take a look at his Merc 9.8 hp. The model number on the cowl is 110. My first issue is that I can't find what the year of the motor is. I've tried looking it up in boats.com and just doing a general google search, but I've had no luck. Here's what I've got so far: I'm pretty sure its an 80's model motor. The decal on the side says Mercury 110, 9.8 hp. The s/n of the motor is 4127365. This motor used to be my Dad's, and my brother got it when he bought the boat from my dad. My brother said it stopped working so he had it in his garage for a couple of years. 2 years ago I borrowed the motor for a fishing trip up north and I was able to get it running, idling and shifting in and out of gear just fine. The motor runs great at idle and you can rev it up very nicely in neutral. When I took it out for the first time (2 years ago) it pushed the little boat across the lake pretty fast. By the second trip, when you throttle up, it just bogs down and doesn't produce much power. It still runs, and it doesn't really backfire or anything, it just sounds bogged down. I haven't even started on it yet, but I figured I'll need to clean the carb etc... It already has new plugs. Any other ideas? Thanks guys!
