v6 Inboard on a 23' GM 4.3 200-235 hp?

[Hooligan]

Interested to know if anyone has any experience with the gm 4.3 vortec inboard/outboard and whether or not it would be an acceptable fit in a 23' CC.

I am considering the original mercruiser 888 from the factory and comparing the 188 hp to the 235 hp numbers of the vortec v6 and considering some weight savings... torque figures may be off from one to the other but no published specs for either.

Do you think performance would suffer with a 4.3 v6?

All thoughts appreciated.
