The high thrust yamaha's are great engines with a super low gear ratio and are generally propped with larger diameter lower pitched props

2.92 ratio on 8T hp High Thrust model
2.08 ratio on regualr 8hp four stroke model

Here's a good article on the 8t from Continous wave.

My Dad had a 15hp Honda HT . . . and it pushed his 25ft pretty well 6 - 7 mph.
