Has anyone used pyrometers with Gil Exhaust? Where did you install the sensors? Is there some area that avoids the water jacketed areas?

thanks

You'd have to have a bung welded into the tail pipe. One per side to be effective.

Tail pipe will be too far back to get the "right " reading. I drilled thru my Rev. Marine (a Gil copy) about 3/4 inch from the head. It was solid Alum there but you should contact Gil or maybe a member here who has drilled theirs will speak up. I had a drain close to where I drilled and could feel where the jacket ended,,try that if you have a hole there. If you can't find the answer, drill from the outside and if you hit jacket just tap and plug it.
