Nicely done! If it were me I would be happy with the current speeds that you are getting, but my boat is electric and the only way it will go that fast is on the trailer.
Have fun with your boat. Best Regards Al Hartley

i just stumbled upon this site and looks like a wealth of information.
I built a little crab skiff during Covid, 21' narrow and pretty light. Power is currently an Atomic 4 gas engine. It is a tunnel drive and turning a 12"- 3 blade cupped "indigo" prop, specifically designed for A4's. I believe the prop was meant to allow the A4 to turn up and run at 1400 rpm.
the boat currently runs about 14knts wot but is used mostly at 2 to 7 knots which guessing is 500- 1000 rpm.
I can only go an inch bigger prop due to tunnel.
I guess my question is where does one start picking the components?
Can I expect any efficiency with existing prop?
thank you for any feedback
