My 1995 Mercury 115 performed well for many years and really isn't performing too badly right now. It seems to be losing power. When new, it would get to 53 mph but the last few years it's dropped to 48 and now 45. It starts ok but will flood easily if you're not careful. The hole shot is decent but the throttle from 2/3 to full adds no additional speed, it just stays at 45 but seems to be using more gas.
I took it to a Mercury mechanic but he said he couldn't find anything wrong. He took it to the lake and said it started and ran just fine. I'm surprised he didn't at least do a compression test. The motor is 20 years old but I go out on only about 3 trips a year, a week each. I use fuel stabilizer and the Mercury fuel treatment. The only other indicator is that at lows speeds it runs a little rough. I don't drain the carbs at the end of the season but I figure the stabilizer prevents varnish.
My thinking is that it's the carbs, 1 or all 4, need new kits. It if were the power packs I think there would be more roughness, particularly at low speeds.
Thoughts? Suggestions?
