94 Mastercraft 205, Chevy 5.7 Indmar. What size is the exhaust tube?

I am to lazy to pull the cover, to measure myself.

Measure the inside of the exhaust flapper on the transom, without removing the cover, should be 3"!
The inside of the exhaust flapper on the thru-hull exhaust fitting is the same size as the exhaust hose inside diameter on the inside of the boat.

I've got the 95 Chevy 350 and I'm almost positive its 4 inches, 3 inches was too small, as I purchased the wrong one first.

I'm 90% sure you want 3" ID exhaust hose, but call your dealer or Ski DIM for confirmation.
