I have a 1995 action craft 17.5' bay runner with a Yamaha 115 HP two stroke. There is no jackplate. I recently bought the boat. It came with a three blade ss prop. I am not sure of pitch of brand of this prop. I bent one of the ears on a oyster bar. I was thinking of getting a turbo props four blade fx4 in 16 or 18 pitch. Please let me know what pitch or brand you recommend.
