For loaded rpm (what happens in the real world) figure around 28,000-29,000 rpm on the water. I have no idea what "reducing end travel" means. If it means running at part throttle - DON"T DO IT! More ESCs are damaged and/or destroyed by extensive running at part throttle than you'd think. Part throttle on a potent system can overheat the ESC fast. It's your boat, you've been warned.

End travel on transmitter throttle settings. On a good quality brushless esc with a high PWM rate running at partial throttle is no big deal, when using proper cooling. We do it all the time on rc crawler jetboats very rare to go WOT.
Brushed esc's have/had a lot more issues with part throttle, although look at rc rock crawlers, constantly at part throttle with good cooling no problem.
My boats all have extensive cooling systems, my neo brushed motors even have both brush coolers and jackets.
