Heres a picture of the tattle tale speedo. and the 900's. We stired the gravel on the river bottom Idling around pirates cove and dinged the props with debris and that cost 4k to have Herring refinish them to like new again, OUCH..
Having a few small dings in the Surface Drive props also caused some other issues. Bob Teague said that it cracked the oil pan that started leaking because the Harmonic vibration of dinged up props cracked the Pan. He said he has seen dinged up props cause even bigger problems thru Harmonic distortion. Crazy Shit.
