Mercury 300xs ECU Re-flashed by DBR Racing & Lightweight Side Air Intake Cover

[Air&Sea]

I am selling a 300xs ECU with a DBR Racing 1.3 version re-flash and a DBR lightweight side air intake cover. I am pretty sure version 1.3 is the latest version. The increased air flow of the side air intakes combined with the ECU re-flash added about 30 hp, a stronger hole shot and 4 mph to my 20 ft Lake & Bay. The side air intake eliminates the water ingestion problem caused by the rear air intake of the stock cover. The rev limiter is moved out to 7,000 rpm's but it still makes its most power between 6,100 and 6,300. I am including all brand new latching hardware to hold the cover to the stock cover pans. $1,900
