when repowering from inboard to outboard, that must change a lot on weight repartition and boat behaviour. might be good on some boats, might be not so good on other, don't you think?

on my project cat. i wont be up to engine install soon, so in the futur, lets say 5 years ahead, outboard may be the ticket to high perf boat. but to know if the boat will be good, or better, with outboard instead of the inboard set up it has now, that is a tough question!

might even be electric powered if I,m slow in the resto and ready in only 10 years!!! LOL :)

Man those things are massive. I imagine that’s another reason why they’re not on more boats, along with price. All that weight directly on the transom.

The Seven Marine outboard weights 1050 lbs vs the Merc 400r at 670. That 800 lbs of extra weight hanging off the back off a twin engine cat is enough to severely change the CG and impact performance.

The Seven is probably a great platform for big CC's, but I'll take the 400r all day for a light weight performance cat.

Yes, and the 670lbs of the 400 was griped about for awhile when compared to the 500lbs of the 300xs.
