At WOT in choppy conditions it's a hold on tight situation, but the boat still feels secure. Slow down to 35knots, and everything gets far nicer and you don't have to hold on so tight.
Fuel economy is great, 4-stroke isn't the fastest engine to get to top speed, and I dare say it would probably be on par just about with a 130 2-stroke engine for top end speed.
I generally cruise between 25 and 35knots depending on conditions, and the boat is very comfortable in this range and the engine doesn't seem hassled in any way.
