I have a 1992 454 Bravo 2, the engine is rebuilt only 1

Customer Question

I have a 1992 454 Bravo 2, the engine is rebuilt only 1 season, the 454 has a edelbrock 750 on it, "use to have 600" The fuel pump is not that old either, Its in a very heavy 27' Searay, I have a fourblade performance prop.
Feels like a slightm miss at idle but smooths right our when accerating, if I run at full thottle it will start to lose RPM, this happened after I replaced the cap and rotor.
Ever since the new engine was installed there has been a slight vibration at different speeds, the marina who installed engine is very good and has a good reputation

Hello. My name is Tan.

Has the marina done any testing to find the issue?

Vibration can be bent prop shaft, engine alignment out or a misfire.
