I am looking high and low here trying to find heat sticks/crayons/pencils to find out if my 200hp merc is overheating or not (alarm comes on, then shuts off, and all seems well) ... I have tried the local NAPA, Thul Auto Parts, and another local parts chain. I have tried various outboard and boat dealers, and no one seems to have heard of these things - the guys at napa looked at me like i had ten heads.<br /><br />ACk!!! I wanted to get some of these before i put the boat in the water today....
