i know these are extremely hard to come by and when I purchased a speedster with fairly bad bow porpusing I decided to make my own. It would have been hard to put trim tabs on a twin 787 (not much room) plus I didn't want to drill into the hull. Anyways I measured my pump over and over again and 3D printed probably 10 until I got the perfect fit. All and all I'm extremely satisfied with the way it handles now. No bow bounce. Rides great! Also put one on my 96 xp top speed gained maybe 1-1.5. Anyways I figured there was others like me who could use a wedge for the 140mm pump. I ran a listing on eBay if anyone is interested
