I am currently running a26 pro et on my 2200 with a 300xs optimax with a sportmaster LU @1.75. I have my jackplate set @ 3. On the gps it shows 82mph @ 5900. I have run 85 0n the gps but had my hands full so i don'tn know what the rpms were. I am wondering if i should try a 28 et or a labbed 28 ET. Should i be running higher than 3 on the plate. any suggestions appreciated.
