Hi, here's what I did to my Impulse 31 (V1) mid-2012:
1. Remove most of interior wood mounting structure.
2. Re-enforced the bottom of the hull with an additional layer of fiberglass.
3. Installed a Leopard 4074, 1800kv motor, with a stainless steel 2pc collet.
4. ESC: Seaking 120A.
5. Prop: Octura x645, balanced, sharpened and raised on the strut slightly.
6. Batteries: (2) Zippy 5S, 4000mAh, 30C, in parallel.
I've been running this setup nearly every weekend and have clocked the boat at 58mph with a GPS. Also handles rough water very well, though smoother the faster :)
