8 head bolts makes this a 6hp. The 7hp and 8hp had 9 head bolts. Its getting hard to find parts for these old model 14 motors. They were made from 1948 to 1966. At first they were only rated at 5hp. Later they changed the rating to 5 1/4hp, then 5 3/4hp and finally 6hp. The displacement never changed, just the rating. When looking for parts, use the model #142302.
