I got that screw back really close. So i did set the motor @4 degrees at idle rpms around 850. In forward timing was also @4 degrees atdc. Ran great. Jumped up on plane. Amazed how it did. 1 problem though. Maxed out pretty much 4600 rpms and gps speed 51. The boat is a 20ft 400 se javelin and the motor is a 225 vindicator. So it should atleast be around low to mid 60's right? Im getting closer though. Prop to pad is 3.5 " and the prop is a 25 renegade. I dont think any of that will make up over 10 mph.
