Mercury – Command Module | Racing Control Module | 77-8M0121241

Overview
This module helps a Verado 80 behave the way it’s supposed to when you’re running a racing setup. It takes the throttle and shift signals from the controls and sends them through clean and steady, so the engine reacts right away without that odd delay you sometimes feel with older parts. The shared guardian feature also steps in smoothly if something goes sideways. It’s a simple little box, but it keeps the whole system feeling tight and predictable.

Performance & Practical Benefits
With this module in place, the engine feels more responsive when you roll into the throttle or make quick trim changes. Shifts come through smoother and more consistent, which you’ll notice right away on fast hole shots or tight turns. Guardian steps in without feeling jumpy or harsh. The whole boat just feels more dialed-in, especially when you’re pushing things a bit.

Why Buy OEM
OEM electronics talk to the engine the way Mercury built the system to work, so you don’t get strange lag or random glitches. They also hold up better to heat, vibration, and long days on the water. It’s reliable gear you don’t have to babysit.
