volvo penta vs Vortec info

[cruiser262]

Hi Everyone

i have a 7.4GI PWTR DP SM outdrive running fine.
I read about the GM Vortec 6.0 L96 engine.It seems to be cheaper,more powerful and smaller.
If one day ,hopefully very far from now ,i will have to repower my boat will be ok to get this engine?How about the outdrive coupling,Ehaust ,manifolds and throttle lever?I saw some dealer selling the ready to go complete engine but i couldn't find anything regarding the outdrive suitability and exhaust system

Any info will be really appreciated
cheers

Have not seen the 6.0 in a boat (Merc or Volvo) as yet but from what I can find out there is very little which is interchangeable with previous SM. Going from a BB to a SM would probably require replacing the transom assembly, exhaust, maybe even engine mount locations. To get more HP maybe go to the 8.2L

Don't go to the 6.0. Seen it done, regrets all around. Sure it's a nice motor but it's no big block. HP ratings at 5000 rpm are meaningless in a marine use. Start by telling us what boat, what drive. we reall cannot answer any questions without that information.
