Default Repower

I have a 27ft older Sea Ray CC currently with the 7.4L 454 which is 330hp with a Bravo III outdrive. She's tired really tired... Time to replace the old girl's power plant. The hull and interior are perfect I love the old girl..

Here's my question, I am researching motors and I really like the new GM 6.2 LSA which has the ability to do up to 550hp. I know the drive will need to be addressed most likely replaced unless it can be rebuilt "beefier" to handle the extra horsepower?

My questions, will the 6.2 LSA be too much horsepower for my boat? My concern is at higher speeds will she get "SQUIRELLY" and can my current outdrive be rebuilt with "beefier" internals to handle the larger horsepower?

We use the boat for skiing, tubing, slow cruises with the family and then there's the day's out with the men hitting it hard if ya know what I mean!


Thanks,

Turn your 454 into a 496 stroker. I have built several and they are great running engines and would really help move the heavy boat.
