I picked up a 25 Tempest+ from someone here on BBC. Plugged all the holes and tried it today. I am running a Triton 19X2 with a 225 SHO. Prop blew out at breakover at 3.5 & 4.0 below pad. I could only get 67.5mph at 6040 RPMs. Prop does not have a nick on it and is supposably stock but I have some doubts just looking at it. I have sent several props to Mark in the past and just not sure if this is a candidate or not. First question is is the wrong prop for the SHO??
