Mine's a 19 ft, but no hull extension. Merc 9.9 four stroke gets it to 5-5.5 kn @ 4500 rpm.Maybe, but my ex yami 9.9 wouldn’t push it that fast. Might get 4.5 with a tailwind

Nice. Do you have a tach for your kicker?
You helped me learn something today
. I had to look up hull speed……“Hull speed is the theoretical maximum speed a displacement hull can achieve without significantly increasing wave resistance. It's essentially the speed at which the wavelength of the boat's bow wave becomes equal to the boat's waterline length. This speed is often calculated using the formula: Hull Speed (knots) ≈ 1.34 * (square root of waterline length in feet). “

Absolutely.
Under kicker power, once the boat reaches hull speed, no sense in trying to go faster. The little auxiliary won't get the hull on plane. It's just more fuel and more noise for no gain.

Where is you kicker tach.
Will kicker show up in Merc smart gauge?

I checked with APM and the kicker is not compatible with the smart gauges. They told me that but thought maybe the rpm’s might show.

Kicker is 2000 era, has manual shift and throttle cable controls. I installed a cheap Faria tach next to the main tach and connected it via the plug on the controls.

That engine isn't even singing songs yet. More like playing the intro

She’s just floating around at that rpm, it really wants more. Just instant power, quite amazing.
