Agree. Unfortunately, the air inlets / arrangement to the individual coolers are different. Not an easy task for the left side oil cooler, by design and by access/ room to fit something in place. Best to tape off the left cooler and install the Gate 9 on the right oil cooler for cold wx operations..I don't have a Gate 9 either, I made my own cooler shutter. If I had a 200 HP, I'd be inclined to install a shutter on both, controlled with one knob.
Hi, Thanks for the link, let me see if there is room to slide the flapper in line. Currently have 1 cooler 100% taped shut.I’m not real familiar with the 200hp layout but would two of these work, one on top of each cooler?
