Clanking noise from lower unit 90 hp

Have a 2015 90 hp. On my 23 ft. Pontoon. Today was running great. Power good @ 5200 rpm = 19 mph / 16 kph. Then all of sudden came out of "no wake" accelerated, and loud rapid tapping noise was coming from lower unit. No loss of power. Any suggestion, or just get it to shop.
ps. Only happens in gear, starts at apprx. 1000 rpms.

Because the motor is in warranty, take it to your dealer. If you are curious, carefully remove the upper drain screw and inspect for metal on the magnet. A fuzz ball of metal dust is normal, but chips or shards of steel are not.

 

Hold a rag over the top screw while removing in case there is built up pressure inside the gearcase. You do not want to wear the smelly burned oil that could blow out with force if there is internal gear or bearing damage.
