We joke about the 53's being loud, and they are, but in a trawler app they will likely run at lower rpm and be ok. The 53 really screams due to it higher rated rpm, 2800 vs 2300 for the 92, but in a trawler you are probably going to run it around 1500, there it is not too bad.
Two main sources of noise on these, blower noise and exhaust noise. The blower noise can be minimized with an intake air silencer, the exhaust noise minimized with good mufflers. Things can be done, but depending on the boat it might not be easy.
Best thing to do is try the particular boat on a run. If installed well, the noise may already be handled.
