Re: QD19 running a little hot?

Jeff, I didn’t get your email. Send some pics of your new motor if you can.
OK, the relief hole is more like an overflow hole. It comes out inside the exhaust cavity at the rear of the mid, about the same level as the telltail. I don’t see how that will cool the exhaust, not much water will ever find it unless the telltail cavity is full of water, plus it comes out about 7.5" above the mating surface of the lower unit and mid, that’s pretty far down. I don’t even think it’s clogged up on the QD, I shined a flashlight up the telltail and saw a little bit of light looking up the mid.
What is the purpose of the cover a couple inches down the rear section of the exhaust cavity? 2 bolts hold it in place. #2 on this diagram.
