This may be a silly question, but I recently replaced my resistor wire with a regular wire and a ballast resistor on my 85 Mercruiser 140. I wasn't sure where to mount it, so I mounted it in the back of the engine compartment with a screw in the fiberglass. I was wondering where they are most commonly mounted on other boats or if it matters. I noticed it gets fairly hot when running. I was concerned with it getting too hot and maybe burning the fiberglass hull or overheating the resistor itself possibly causing it to fail. I haven't had the boat out yet. Wanted to get some oppionions before I get out on the water. Any info is appreciated.
