Corsa above water exhaust Rinker 282 installation question

[michaelpkcmo]

i have a 2004 Rinker 282 with 2016 383 mag stroker engine which replaced the original engine.

when the previous owner added the new motor thy added the corsa above water exhaust in addition to the thru hub exhaust.

Recently the engine hydrolocked thru the exhaust riser and manifold.

i dont think there is enough vertical rise from the exhaust outlet located under the swim platform to the top of the exhaust riser.

Should there be a flapper inside the exhaust before the exhaust riser to keep water out?

I Also noticed that the exhaust flappers at the end of the exhaust dont close fully when the engine isnt running.

I am attaching photographs of the current installation for review.

I appreciate comments on the existing installation.

Assuming the installation is incorrect what steps can I make to correct the installation?

Does it make sense to exhaust ou the sides instead of under the swim platform?

Thanks

Mike

Many times the water will come into the thru-hull exhaust durring launching.

The installation looks like so many transom mounted thru hulls.

Ditch the thru-hulls, and put a 6" riser kit in... That will fix the problem.

Look inside the tips, they should have baffles in them, if there just empty tubes this is a problem. There is no issue with the external flappers being away from the tube, the water will push them closed so long as they are in good shape.

Mine looked about the same when I installed them, but also never stopped real quick
