SORRY, I offer moble service but thats alittle far for me, unfoutuatly I dont know anyone out side the U.S.

Thank you for all the info, and as soon as get this drive repair, I will post the solution

My money is on the U joints as well. They were probably getting bad any way, and having the drive trimmed way up with running probably did one in.

Be carefull if you hear it ever again. If the u joints completely let go, it will most likely destroy a bellow and in comes the water.

Never run the motor over 1200 Rpm's with drive raised above trim range. This will over stress the u-joints.
Also critical is to use the L15-1NF factory spec u-joints or Mercruiser permalube u-joints. Anything else will lead to failure and we dont want that to happen.... BBB

When the drive was up the motor was only turning about 700 RPM, gust phone the mechanic and they are going to look at it today.

let us know how you make out

my u-joints were on my bravo 1 were rockwell had a # on them changed them both out for 40.00 ordered them through a local auto parts store and have had no trouble

Thank you everyone for giving me the info about that noise.
My mechanic phone this morning and told me that after opening the outdrive, that I will have to change the upper gear kit, since the serial number starts with OL, Merc has change these gear with thicker gears. $ 2600.00 job, this suck specially because I never hit anything and never went low on gear oil and always change it every 50 Hours with a 6.2L engine

Its been a while since I checked on gear repair, replacement, but 2600 sounds kinda high to me.... :

Maybe someone else on the board can chime in on what something like that cost,,,hell it may be right
