Take the transmission cover off. It'll have a 48 stamped on either the right or left side if it is 48

The bottom is 48. The top is what ever you count to. I don't think the top has ever changed. I think the ones changed around 2012 went from 42 to 48 but I may be backwards.

The bottom used to be 45, changed to 48 around that time. The top is 36, I think. Marcus will be along shortly to correct me if it's 38.

If Russ says it is, then it is. Thanks for the correction on 45 and not 42. Drinking beers and watching Alabama hopefully lose doesn't make for a strong memory of obscure facts.

Away from you. Check your weight distribution first and also prop plays into effect. Since you have a worn prop, may want to wait till you have a new one and see how that plays in.

Trim level affects the felt torque a lot, and a fresh prop will change where it's trimmed for best thrust. Unless you're gonna use that prop a while, just wait on the bending stuff.

Top gear is 38 Current bottom is 48. Used to be 45 lower, but was changed around 2011-2012 ish. The CDI motors additional charging system put more load on these units aswell as larger boats, 3 blade propellers were coming out; so they needed a lower gear ratio.
38/45 = 1.18:1
38/48 = 1.26:1

To be exact they changed the bottom gear for 2013!
