Have a 1984 222 xf wa and repowered it with a 2010 225 e tec.Love the motor but not getting the speed.It came with a 14.75 19 prop from evinrude.I am only getting 5200 rpm wot.I had braid wrap in the hub while anchored out fishing.GOT it out of the hub , finished fishing and docked the boat.Noticed a 2 ft. pice of braid, un wraped it and here is one of two questions I have.Without taking the boat out of the water how can I tell the seal is still ok?And number two is would a viper 17 get me the extra speed and rpms.Looking forward to some advice, thanks.
