[QUOTE="LionHeart, post: 435719, member: 22379"] So I finally got a chance to test the motor after carb clean and rebuild, along with lower unit service and new spark plugs. I've been really anxious to test the performance since this is my first outboard. It started fine with just a few pulls but needs a tad bit of throttle to run at idle. I couldnt wait to test the top end speed but was kind of disappointed when I topped out at 11 mph. The boat is a 14 ft. Alweld so a little on the heavy side. I had another person weighing 150 lbs. A trolling motor, battery, and 15 lbs. anchor, so roughly 385 lbs. In the boat. Is thisnormal? The compression is 115 on each cylinder. While I know very little about outboards, it seems like it may ne running a little rich. After about a 20 minute cruise, I took a look at the spark plugs, and here is how they look. Is this normal for 2 stroke after only 20 minutes? Something just doesn't seem right. I'm trying to be patient, but after a month of ownership I'm getting ready to enjoy this boat and stop tinkering. Any advice would be great. [/QUOTE]
