The boat is a 2010 185 sport, 190hp 4.3l. The original owner changed the stock 14.25 diam. 21pitch 3 blade prop for a Revolution 4 14-5/8 diam. 19 pitch SS 4 blade prop. I poked around on here a little and it sounds like the this diameter and pitch is a pretty good fit for this boat. Are Revolution 4 props good? I am researching automatic trim tab controls, I have a question on the Lenco Auto Glide. Does anyone know if it retracts the trim tabs when the engine shut off like the Bennett Auto Trim Pro, and Mente ACS do. I can't find anywhere where it says it does this, only that it retracts them when reversing.
