Location: Southern Ontario, Detroit River and Lake StClair | I have a 1993 3 cylinder 50hp Mercury. I have it on a Lowe Roughneck 1860VT mod-v jon boat. I'm running a 12" 4bld aluminum prop. Dry weight of the boat is around 650lbs. Lately the motor has been real sluggish coming out of the hole and up onto plane. I cleaned the plugs and it made a bit of difference but not much. I checked the compression and its about 107psi on all three cylinders. It used to jump right up on plane with no issues so I'm kind of wondering whats up. Top speed is about the same at 31.8 mph loaded. Anyone have any thoughts?
Thanks
