Sounds like your old motor (25hp) had a prop with too much pitch and that was keeping the rpm too low and not letting it reach it’s proper operating rpm. While some engine troubles require the expertise of a boat mechanic, others can be easily resolved by following the right troubleshooting steps. It's a good idea to always use a fuel stabilizer such as StarTron or StaBil ethanol formula. 2) The setting varies depending upon the exact application.
