I finally got my spark problems fixed, my wiring gremlens addressed and really appreciate the help I have been provided here.
I have a few last questions,
First, when I shift into forward or reverse there is a slight grinding.
Where do I check the gear oil on the '72 165? I found the lower drain plug but I couldn't find an upper vent plug on it anywhere. I drained the oil that was there(maybe a qt) which looked good, no water or milky color, and refilled it from the bottom with about a quart.
What all could cause this grinding? It's not bad, and only grinds for a second but I know it cant be good.
Also, when it is running I hear a sound from between the outdrive and the gimbal housing that sounds like a small jet airplane. The exhaust bellow is completely torn, could this be my noise or is it more likely a gimbal bearing?
Is there any way to check the bearing without removing the outdrive completely?
It looks like you can change the exhaust bellow without removing the drive, is this correct?
Once again, I really appreciate all the help I have been offered here!
