Connecting a PWC muffler to a Perkins 4.108

I have access to used but in very good condition muffler from a 1994 Seadoo similar to the one in the attached picture. It is rated for a 78 horsepower gasoline engine. I'm considering connecting it to my Perkins 4.108 as a part of my repower. The exhaust will be exiting from the transom, above the waterline.

Considering PWC's have a wet exhaust; and considering this muffler is rated for a 78 horsepower engine (and my Perkins is 48 horsepower), I'm wondering if there are any drawbacks to using this unit instead of a marine waterlock muffler. This unit is available locally for $30, which is 1/8th of the cost of a brand new Centek waterlock muffler.

Thanks in advance for any input.

Re: Connecting a PWC muffler to a Perkins 4.108

I can't tell the size of that, but a waterlift for a diesel must be able to have enough volume to hold water without letting it backfill into the engine. I imagine your diesel pumps more water than a jetski.
