    Custom air vents

    Looking to see what some people have done for some vents to get more air into the hull and let some heat out (towards the back of the ski) post up some pics!

    Here is what I did. It's two flow-rite 14-189 screens.



    Don't think it made my difference for the motor. I didn't it mostly because for a short time I was still running stock 190F thermostat (closed loop) and wanted to let some of the heat out when ski was off. A 160F thermostat did a much better job at that so would I do it again?....maybe not

    160F thermostat keeps engine bay noticeably cooler? I just put one in, but won't be able to test it for a while, mostly for that reason. If engine bay is cooler than intake temps must be a little less I would imagine.

    In Florida, huge difference in under seat temp. With stock 190F, I would pop seat off and it felt like a sauna. With 160F it was so much cooler in hull. Since surface metal is cooler, and water that splashes on warm parts don't create steam. Again, big difference in Florida where its already hot and humid - YMMV.

    There's a neat thread somewhere around here where a guy drilled out the little hood vents and installed flow-rites in the front and under the seat. I cant recall if he ever reported back with his findings, nor can I find the thread.

    Either way, the setup looked like it would dump heat very well. And dumping heat is always a plus.

    I remember reading that thread, he also said the hood started to vibrate at high speeds
