Hi all
I have a 40' searay
that needs engines. Currently it has 454's

If this were your boat, would you re-do the existing 454's and beef
them up a little?

Or put a pair of bigger 502's in it

40 feet is pretty big for gas engines but if you are committed to
that plan, consider the 496 MAG or HO over the 502s. One of my
neighbors who really knows engines says that the fuel injected 496s
offer better economy, performance and durability.

He could have had anything he wanted on his own boat and chose the 496
MAGs.
