Hi, I'm wondering if anyone can tell me if an 8HP 2 stroke would be enough to get my 12' Aluminum up on plane (2 guys on board). It's an old Sears boat that probably weighs around 150lbs. I had an older 9.5HP Evinrude that got it up on plane pretty easily with some gear and 2 guys on board. That motor has since died and I'm trying to decide between a Yamaha 9.9 HP 2 stroke or Yamaha 8 HP 2 stroke. I know the 9.9 will get the boat up on plane easily but it is quite heavy (79 lbs), the 8 HP is relatively light at 60 lbs. Since I'll likely be carrying around the motor quite a bit I would prefer a lighter one but not if it won't get the boat up on plane. Thanks in advance.
