Hello all, I've been a member for a while but I think this is my first post.

Anyway, I've got a 16.5ft aluminum v-hull fishing boat with an old 1996 30hp mercury 2cyl 2 stroke tiller. I've been thinking about repowering for a long time. It feels just a bit under powered. I get about 26-27mph at 5300rpm when I'm alone in the boat. The boat is rated for a 40hp. I've been doing some research and came across the 40hp command thrust Mercury that can be upgraded to a 60hp with just an ecu swap and restrictor ring removal. What other makes/models can be upgraded like this? I want to stick to a 40hp due to the capacity plate but I'm not brand loyal haha!
Thanks!
