Avon SR 5.4, 19 pitch alu prop, me and 2 small kids + 70 l gasoline. Today 43,5 mph(gps), not totally trimmed out(no chine walk) so maybe little more to come. Need to test without the kids....

Today, no kids, 50 l gasoline and reached 45,4 mph. If having the time trying to remove the anti fouling some day, then the target will be 47. At 45 pretty stable, only minor tendency to start chine walk but did not start yet. Lightly loaded the 19 inch is much better than 17 standard alu prop. Revs around 5400+ rpm(forgot to check at top speed).

There is also a minor hook in the bottom just before transom, sorting that out might further improve things a litle.
