First time. I recently took my 75 out and it ran great at high speed for about 2 min then bogged down to a slow crawl and eventually stalled a few times. Had to nurse it in very slow. Next day same thing, started great, ran fast for about 1 min, then slowed down to a crawl. Boat was on a trailer for a few months, but ran at least once a month. I ran carb cleaner through the carbs and same problem. Any suggestions? Thank you......

Probably bad fuel, water , or trash plugging things up
or your buzzer alarm is not working and you are getting into safe mode due to overheat or low oil level safe mode limits RPM to about 2K
