at 1800, it's a little cheaper than the 8hp. Assuming there are no drawbacks to the 9.8, I figure it's a decent deal. Higher resale, will push any boat I am likely to buy in the foreseeable future. Also, given that I figure I won't be running it full out, hopefully it won't be very stressed.
I do wonder: two identical boats, side by side, one running the 8hp, one running the 9.8, which uses more fuel?
