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.

besides the performance,allready dicussed,if your plan was to reuse the existing drive yu were going to make a huge mistake - very costly mistake as well.the older alpha drives,these have high pressure low volume water pumps - the newer alpha gen II drives have a high volume,low pressure water pump - with all that,the older drives are not compatable with the newer vortec engines...
the smart play for you,is to pick up a package -read that as engine/drive and transom assembly - if you're really smart,you're gonna go for the harness,smart craft set up including guages.doing this,you're buying new,not used/rebuilt ,and the best part,you're not attempting to "adapt"...get the merc 5.7 MPI/bravo drive - this is what's pushing my 23,it's a bulletproof,incredibly fuel efficient package - it's an '03 set up,have had ZERO problems !
