Mercury 4cyl. w/ aluminum head?

[fletch44]

I have a friend that asked if I had ever heard about a Mercury inboard 4 cyl. with an aluminum head(Possibly 460L ??).Late 80s' about 190HP. Does anyone have any info about these motors? Any good?

I do not think it is alum-head. but they do use a alum block with cast 460 ford head. they can be good but are sometimes a pain with leaks great for salt i would guess. the problems i see here in mi is head gask and cracks around valve seats.
