I had a 300hp Mercruiser (7.4L) which is a 454 ci Chevy block and a bravo 1 drive, It was way heavier than 900 #, all together it was close to 1300#.

I don't know the weight, but the current 300HP Mercruiser is a multi-port fuel injected 5.7 liter,(350ci) small block.

One site lists the complete package for a Mercruiser Magnum 5.7L 300 hp motor, transom mount and Bravo 2 drive at 1083 lbs.

A big block will always be heavier than a small block.

A small block will be heavier with a bravo 2 drive than a small block with a bravo 1.

My numbers come directly from Mercury (in brochure form).
