I have 2 yamaha 250 4 strokes on a 32 regulator with 900 hrs, recently started adding from a gallon to two gallons of oil per trip at 60 to 100 miles offshore. any suggestions on what might be? no oil under cowl, seems to be coming out bottom, and not much smoke if any.
 
Check the driveshaft where you can see it for about an inch under the lower cowl. If you see oil on it you probably need an oil pump and a sleeve on the seal surface of the crank.
