I have a yamaha performance series 14.25 X 16p ss prop I would like to use on my 2001 merc v6 150 carb salt water outboard motor. The thrust washer I have now with my michagan 14.5 X 17p ss prop lets the yam prop seat too low in the housing causing interference. Can anyone supply a part number or suggest a suitable replacement washer so that I may utilize this prop?<br /> John
