Pro-drive- Highly engineered. Solid and reliable, but lots of moving parts. They have full power reverse.
Gatortail- My personal favorite. Belt driven, power trim, available in regular or reverse models. No full power reverse, but they just came out with a reverse plate that improves reverse performance tremendously.
Mudbuddy- Belt driven, power trim, no reverse, but you can get these engines in multiple configurations ranging from 9hp-70hp (although anything over 35hp warranties are 90 days).(Other brands only offer hp ratings up to 36.
