Kicker motor size for Gulfstream?

[yellowlab]

What do you recommend using to push a twin screw Gulfstream to reach proper salmon trolling speeds? I'm hoping to get by with a Yamaha T9.9 XL shaft, but wasn't sure it would push it appropriately? Anyone have a good fixed bracket recommendation as well?

Thanks!

I put a fixed bracket on my 208 with a 9.9 high thrust Yamaha
I had a similar setup on my 2359 Trophy with a 9.9 high thrust Evinrude.
It would push it 5 mph at top speed.
We usually run 3mph for salmon and rainbows in Lake Erie

9.9 high thrust will definitely work however at the faster trolling speeds the engine will be revving at higher rpm's and the noise can get aggravating for long lengths of time. If you're ok with the noise, fine. But a 15 hp kicker will do the same job just much quieter.
