'04 180cc prop size??

[simplymajic]

i recently purchased a 2004 Sea Pro 180cc with a 4 stroke Johnson 140.  I was hoping someone could tell me what would have been the original prop size for this package?  I feel the package is under performing.  I can barely get 5000 rpms and the hole shot is more like plowing snow.  At 4600 it maxes out at about 38 mph, the last 3 to 400 rpms just spin.  It's a stainless solas prop and I can't read the prop size. I was hoping I could get some recommendations as to where to start.

Thank You

Prop size should be on there somewhere, you might have to take it off to find it. With that info we might be able to help somewhat if someone doesn't have something to compare with, otherwise I'd suggest contacting Ken @ propgods. www.propgods.com/Content2/Default.aspx
