Heat in Bilge area?

[1BadTundra]

I'm in the process of running wire for a lot of different lights in our 212x, including transom lights for underwater lighting and lighted cupholders on the swim deck. Question, is anything in the bilge area creating enough heat to melt the insulation on wiring? I'm doing everything I can to tie the wiring up, we are mounting sticky backs with 5200 all over the inside of that area, so the wiring will be cleaned up nicely, but if there is any incidental contact, does anything back there carry enough heat to melt the wiring?

Nothing but the motor and upper exhaust manifold.

The motors are up in the engine compartment, I'm referencing the area behind it, under the swim deck. I have the hatch open and the tray removed. I see water boxes, and a lot of plumbing. I'm wondering how hot all that gets.

Not sure how "hot" anything back there gets....it will be warm for sure - but I've not seen a post where anyone has put a heat gun to things back there after running. I've always zip tied my cables to existing harnesses that are screw mounted to bulkheads...so no worry about heat melting adhesive.

The water coming out of my exhaust port is 140 degrees. Not sure how the exhaust tube goes threw the large water box the outside could be cool .........never temp the box

I figured it'd be about that... I tried to hit oem wire harnesses where I could, but coming from the transom to the back of the wall separating the motor compartment, there weren't a whole lot of places to fasten the wires. I put up my own sticky mounts, hopefully they can keep the wiring clear.
