What is known as a 2+2 motor.-----The bottom 2 carburetors run very lean below about 1800 RPM.----It only runs on the top 2 cylinders at idle.---Do a compression test.-------I suggest a water test before handing over your hard earned money.

interesting, maybe good on fuel? at idle perhaps? it will be going on a 16' hull that probably doesnt even weigh 900 lbs
