my 18" tinny is rated for a 115. I have a 50 and can hit 27 with just me which is fine but the boy in me still wants a 115. Cant imaging that kind of power back there. The fifty with more than an extra small adult and a kid or two just struggles.
i am about done with a approx 600 sq ft deck and prob 98% was perfectly fine. What makes it more incredible it that I did a pick up so they just picked and loaded for me.
