New vs old mercury edition

[Matt Torino 150]

This is the boat I plan to slap a merc on. It’s a 16’ boat with a max hp rating of 150hp however I’m not afraid to over that maybe up to 250 or 300hp planning to add a pad for more speed.

So so here is the new vs old
all of these new 4stroke motors are light compared the competitors in other brands but are still pretty heavy compared to some older engines. So here’s what I came up with-
New
115 pro xs @ 359lbs good power to weight ratio with boat
150 pro xs @ 459lbs 30lbs heavier than the Optimax it replaces
200 pro xs v8 @ 512-540lbs just love that new sound and not that much heavier than the 150 if configured correctly

Old
135 Optimax @ weight uncertain. They are the lower hp v6
150 Optimax @ 430lbs. Maxes my boats power rating
2.5 efi race motor @ weight uncertain. A beast of a v6 with neck snapping power

Weight is not entirely accurate but those are my top pics to retire the Evinrude
what motor will best suit this Tahiti Torino 16
