I originally had the 1 ½” transom exhaust outlet that was used for the A4 on my 38. The 38 has a reverse transom, so the outlet was angled up at around 30 degrees. The PO had installed a Universal M35B, the installation manual for which calls for a 2” exhaust. So the water flow through my exhaust sprayed out and up to form a rooster tail behind the boat. Wish I had a dollar for each time someone on the ICW called me to tell me I had water shooting out the back – and going downwind with the engine running above idle was pretty damp and smelly at times.
I bought a piece of 1 ½” heater hose with a 45 degree bend in it from my local Advance Auto, cut off the excess hose, and secured it to the exhaust outlet with a band clamp. That pointed the water spray down until I got a chance to put in a proper 2” exhaust outlet with a flapper valve, which is in the hull under the transom overhang, as part of the engine replacement in 2011.
