Last year, final test run before winter lay up, ran 7k rpm, approximately 52mph indicated @ 50 degrees out.
This spring, after working some bugs and changing some parts, not getting the same results. I was indicating 6,600 rpm's 52mph indicated @ 75 degrees.
Things I changed this spring:
1. Removed beach house sponsons and installed new OE sponsons
2. Replaced stator with a new OE, and connector replaced (fixed charging issue)
3. Replaced Oil tank with new (fixed oil leak)
4. Unbolted carbs, reset my needles after futzing with them last year to try and figure out my large under rpm issue (turned out to be exhaust hose)
Seems I was approximately 300 rpm's short yesterday. Indicated speed seemed about right though.

- Low needles set to 1 turn out
-High needle 0 out on mag, 1/2 turn out on pto (1997 service manual says 0 out for both high needles)
5. Rerouted pisser to front starboard side so i can see it when running vs out the back. Used 1/4" line and fitting. The route is twice as long as OE. The outlet is 1/4" vs the small 1/8" hole or less out the back. (possibly less backpressure?)Seems I was approximately 300 rpm's short yesterday. Indicated speed seemed about right though.
