Hi
I just purchased a 1988 Regal Sebring with a 4.3 Mercruiser IB/OB and they did not have the manual anymore,
how can I find out what HP I have on the Engine
Thanks

Most Regals of that era came with the 2 barrel carb. I can't remember ever seeing a 4 barrel option on one of the late 80s... So you most likely have a 175HP. Is your engine flame arrestor cover intact? It should be listed there.
