Real quick question..One of My 502's stalled due to a vapor lock issue that I am in the process of addressing. When I re-started the motor obviously the transmission was not in gear...the motor went immediately to red line..In my panic, I shoved it into gear and of course, I heard a sudden clunk...Won't go into forward or reverse. Finally, when I put it into forward or reverse, RPM's only climb, no action from trans. The only question I have is what did I break? Engines starts and runs fine. but it sounded like something simple snapped. Literally, it sound like a two cent part broke..but if it's like everything else on this boat I have fixed, I know it won't be. thanks, rick
One other thing...Port motor...Counter Rotator...Thanks

Hard to say what broke without taking it apart. You could have broken a shaft or the coupler. Or snapped the input shaft. Motor at redline, anything could have broken.
I would pull the drive and pull the back and top caps. Look for metal chunks. If nothing.. seperate the halves and look at the vertical shaft and coupler..

No good way to speculate.. A look see will tell what weak link let go.

Hope this helps..

Had a similar problem a few weeks ago, except that I was skegged into the sand and I was at only 1200-1500 rpm. Accidently bumped it into gear and heard a small snap. Had to go fish the prop out of the sand since the prop shaft snapped. It also twisted the driveshaft. Mine seemed like it wasn't shifting into gear until I listened very carefully and realized that it actually was shifting but there was no prop. But, like Mr. gadgets said, there is no way to know without pulling things apart.

Its a lot more than than a 2 cent part that you broke. You better be hoping that its less than 2 grand. Could have broke the cone clutch or gears in the drive or the coupler or input shaft or a combo of the them.

From your description of what happened it will be serious damage. Sorry, it will be no cheap easy fix on this one.

believe it or not...the only damage done was a completely incenerated prop hub...checked lower unit oil screw high side and low...no metal.... replaced the hub all is well

You are one lucky boat owner! Bravos often turn to pulp with less abuse than that......

Wow your lucky. That gear set is about 1700 big ones.

I hope you bought Loto tickets that day??

One thing to keep an ear open for.. is collateral damage. Although the hub is the only thing apparent at this point.. something else could have been stressed.
I have heard so many times, "I was just cruising at 3000rpm and bang".. Well the question is, what did you do previous to the failure.. Damage can occur and not show up for several hours later..

I hope in your case that the hub was the blown fuse and nothing more.. I would buy loto tickets for several weeks..
