I have a 40 HP, 1986 Yamaha ELJ (2 cycle, 3 cylinder) motor. In fall, found water in gear case oil. After searching for replacements which are available, I decided to try to replace the drive shaft and prop shaft seals. Following the recommendations of Dangar Marine and the precautions of the "hack method," I was able to remove and replace the seals. I did a pressure test using home materials after putting the unit back together and inflated to 15 PSA. Pressure was maintained above 10PSI for 3 minutes, and was 6PSI at 8 min. I wonder what the standards for satisfactory pressure test are? thanks. Peter, east end NY
