The only real difference (other than the fine details of the design) between a cat and a tunnel is where the motor sits (inboard or outboard).

FYI .130" flex cable works great in the stock O/B lower, Bonding the cable to the stubshaft with Loctite 603 seems to work abit better than silver solder. I ran a stock out board for 14 months with a 3660 2700KV motor on 3 cells and X440 Prop with out major issue, only mod to the leg was the flexishaft in my previous post and changing the bearing nearest to the prop to a 8x4x3 from the stock 8x4x2
