Suggest all around I/O power for Sceptre....

[bobfish21]

1974 23' Tsunami, repowered with 2000 Mercruiser 5.7 LX 260 hp EFI, Alpha gen II.
My cruise is right about there, 25 mph at 3000, never ran her higher other than to make sure I was turning where I should.
Top end falls a bit shy of your 45-50, more like 39-42.
Had the same boat with a single OB when I was young, the I/O hands down way better ride- 1000lbs of iron in your bilge will do that.
In 17 years I've been through 1 set of manifolds/ risers, 1 oil pan, 1 gymbal bearing and 1 starter.
Salt water cooled, boat was in a slip from 2000 to 2006, so no flush after use.bought a 35 Bruno DE, so after that time, little use- maybe 550 hrs total on her.Never had any issues with corrosion, block always contained either water or antifreeze.
Boat is for sale on here.

Regarding bravo1x drive, I would encourage you to explore using a bravo3x drive. I repowered two boats within 5 years, the first bravo1x. Works great, it is bullet proof. I didn't use the bravo 3x because I had heard horror stories about corrosion in salt water. Both boats are fresh water cooled. The second one i used the bravo 3x. I have had it 10 years, and couldn't be happier. I think it gets a little better performance , as well as handles better due to the counter rotating props, especially backing and trolling slow. The first was a mercruiser 5.7l with full fresh water cooling. The second is a yanmar diesel, 6 cylinder, 315 hp, full fresh water cooled. Both boats about the same size and weight. Gas boat burns about 10 gph, diesel about 7 to 8. Both will push boat to 45, with 28 to 32 mph being good cruise speed. If cost was close, I would use bravo 3x.
