Re: New to boats and this my surprise you but i have a motor question
I don't have any specs for you rebel, but generally speaking the four stroke will give you better fuel economy and run a little quieter but will come with a higher maintenance burden, while the Opti will give you better hole shot and maybe a little more speed (can't say for sure on the speed) than the four stroke but burn more gas. I'd say the main factor in your decision should be how you plan to use it. If you'll mainly be cruising and trolling you'll probably be better of with the four stroke; quieter and cleaner and happier at lower RPMs for extended periods but still enough guts to get you off the water quickly if necessary. On the other hand, if you envision a lot of water sports and a desire to get to a spot quick you'd probably be happier with the Opti. In the end it's a question of happier, not happy, because you'll be happy with either motor. Which one will you be happier with? That's ultimately up to you.
