If you have a look at his old thread you will scroll down to see the cowl with 2.5 Written on it, I still have that cowl as it was then if you are interested, I think i have a pan too?
Hi, can anyone help? I have a 21' Phantom and i have a Mercury 250xs with a 1:62 Sportmaster gearcase on the boat turning a 24" ET Lightning Prop at 5700 RPM GPS speed at 75MPH, would it make a difference in speed if i would change the Gearcase Ratio to 1:75 and would you think i will gain any speed??
