The 12 degree may not even get up on plane with a 115 on it
Depending on how concerned you are about weight, you may want to double check specs on The Suzuki. It seams to have gained weight. They now list the weight for the 25” 150 at 522 lbs. The good news is the 200 only weighs 7 lbs more at 529. The bad news is it’s over 50 lbs heavier than the merc.When I first contemplated power for my 200 CCP rebuild I was thinking Suzuki 175 or 200. Now I’m leaning toward the 150 Merc for the lightest weight. I went full transom with a bracket, so my motor will hang further aft. Your 222 should be fine either way. Might be worth waiting for the new Merc V6 if you want 200 hp.
