Tohatsu EFI motors upgrades sharing same CC powerheads as in this inquiry asside from the carb restrictions to achieve more fuel intake also needs higher timing advance values, that's why need to swap next higher HP ECU's or the motor won't work right.

If that Zodiac is small and plan using it with say 2-3 light souls on board, a prop maximization to a less prop pitch it's the cheap way to go alternative to save big cash...

Happy Boating
