I currently own this 70 HP NS70A. I know it is old (1985) but still runs pretty well. I run at about 35 MPH in my Mcgee Craft Angler. I was looking at impellers for this thing with part number 35365-0210M. On closer examination, the sizes for that impeller listed under that part number are all over the place. Example as listed by one supplier is OD 60.84 mm; ID 17.20 mm; Height: 23.8 mm. Another supplier list the specs for the height at 23.30 mm for that part number. Yet another shows the OD at 60.50 mm and the ID at 17.30 mm. Totally confused at this point. I am wondering if the differences are so marginal in size that it doesn't matter? Any insight would be appreciated to be sure I get the right part.
