    Default Repowering Hull vs Horsepower

    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,

    Hey there. I just found and joined this forum because I have a nice marine engine that I inherited and I am interested in selling it. I want to find out what it is worth and maybe find a buyer. I saw your post and thought you may be interested. I'm not sure where you or most members of this site are located. I am in SC. The engine is a freshly rebuilt GM 454, probably the same as your original so it would drop right in. I have all the specs. New brand name internal parts. Less than 50 hrs on the motor. It sounds great! Dyno'd at 535 ft-lbs of torque and 463 hp. Let me know.
