Ok, I recently bought this boat, and it hasen't been in the water yet. It's an 87' model 175 with oil injection, and I'd like to make sure its operating properly.
So far i have ran it on a portable tank mixed 50:1, and it seems like its getting a lot of oil by the trail from the exhaust and smoke.
But, i'd like something a little more scientific.

Do I just keep an eye on the level of the remote pressurized tank, or is there a better method?
