Rather than thinking of a 2nd engine as a "kicker", think in terms of auxiliary power. The auxiliary power should be of sufficient size to maintain headway and steerage in a blow. Many a "kicker" choice is selected/sized for trolling applications (using main power for trolling in rougher conditions), but the "kicker" cannot maintain headway/steerage if the main power fails in rough conditions. Don't undersize a "backup"...
Be careful... in many tournaments and likely NYS waters, that might be interpreted as an illegal fish. “Landing nets may be used in completing the catch of a fish hooked by angling“.
