so far, that's good news! I hope it works out for ya, and the clean internal engine parts, ya always want to see that:)...those engines are good. I had a 97 Ranger with the 2.5 5 speed, but it had a 373 factory ring, pinion gear, it was made for hauling, wasn't much on the take off, but would pull my other boat no problem...
good luck, and update us when u find out what happened, and what fixed it..
