Just wanted to post this to make it easier for those who want to install a tell-tale or pee tube on their Force motor. Mine is an 88 force 50hp. As suggested, I removed the pipe plug located on top of the head just in front of the thermostat cover. Like everyone else, I had trouble using a slotted screwdriver and used a small pipe wrench to back it out instead. I guess a good pair of vice grips would work too. Be sure you get a good bite on it before trying to unscrew it.
I bought a fitting at Lowes plumbing dept. It's called a 1/4" x 1/8" Tube to MIP Elbow w/insert. I had about 18" of 1/8" plastic tubing like the type used to hook up an icemaker on the fridge. I installed the elbow in the hole where the pipe plug was, drilled a small hole in the side of the lower cowling (on the right side) hooked up the tubing , and routed it through the hole in the cowling. Took about 15 minutes to do and now I have a nice pee tube that shoots water out the side of the motor where I can see it when I'm running. Sure beats those spittin" vent holes at the back.
