On my 02 Tr 21 the remote Oil tank fill is labeled "Gas". I had a kid at the fuel dock a few years ago fill it up with gas. Luckily I was not far from my truck and trailer and was able to use my TM to get the boat out and drain oil tank. I couldn't be mad at the kid as I was inside the store and told him to put 20 gallons in. When he told me it was almost full already, I knew we had an issue. And until then I never realized my oil fill says "gas" on it.
