Human: Hi All, I recently bought a boat with a 150 merc fourstroke and smart craft gauges. Everything works fine except the fuel gauge, it always wants to read 100% full.

Human: Hi Folks, Just bought a little 12 ft. fiberglass boat (490 lbs) & need a battery for my Minn Kota 30lb trolling motor.

They are less than $20 from factory.-------Not worth shopping for lesser QUALITY on these I would say.	Normal because you ran it for 5-10 minutes the motor does not get warm enough to burn all the fuel mix off. You probably would not have noticed it if you didn't run it to flush it. Otherwise perfectly normal for a two stroke outboard
