Jeff, I understand the sequence of events - first picture Gregg in boat, second picture, no Gregg. These were taken at White Bear Lake with Mr. and Mrs. Retro. with Mrs. Retro taking the pictures.
The second picture was taken with the SRX prop churning up the water in a show-no-go slow turn for Mrs. Retro. The over the exhaust hub prop was not biting yet at this slow speed.
Whether Gregg or I go faster is a toss up at this point. Gregg gained alot of speed by mounting his motor higher. I may have to do the same to keep up with him.
