That's about yer lot, unless you want to bung another 100hp on the back. That's a big trawler for a 200 Honda. You might gain a knt or two by playing with props and lose on pull-out and acceleration.

Yep have to agree with Mollers here. Thats a big lump of a boat youhave beneath your feet and if you want shift it to match your ambitions you will have to dig deep and put another engine on the back. As M says at least another 100 gegees!!

I know a guy with an 8m humber and he gets about 60mph on a good day. However he has twin Etec 200hp motors!
