Tige 2000 21v with teak. Deck mounts with three female brackets that slide over male pins bolted to transom. I have been hunting down vibration and note that the exhaust bubbling underneath the deck causes a shudder in the deck. I dont remember this prior season and was wondering if anyone has ideas on tightening it up.

Is your teak deck coming loose of the brackets or are the brackets rattling around?

Brackets rattling...
