Frequently Asked Questions

The Holley 0-82500 Marine Avenger features crucial marine safety design features, including J-style vent tubes that route fuel overflows back into the throttle bores during rough sea conditions, PTFE-coated throttle shafts to withstand corrosion, and a specialized fuel curve calibrated specifically for continuous marine engine loads. It fully complies with US Coast Guard safety standard J1223.

The 0-82500 uses a standard Holley 2300 2-barrel mounting flange pattern with a 1.750" throttle bore. If replacing an original factory marine 2-barrel carburetor (such as a Mercruiser Mercarb), check your intake manifold bolt pattern as a 2-barrel adapter plate or linkage modification may be required.

The factory preset electric choke requires a key-on +12V DC power source that only receives voltage when the ignition key is in the 'ON' position and the engine is running. Do not wire the electric choke lead directly to the ignition coil, as this can result in insufficient voltage to both the choke thermostat and ignition system.
