Hey Everyone...newbie here to the forum and boats in general. Recently purchased a used center console 2005 proline 17. The boat has a 2002 Yamaha 80HP 4 stroke motor with a 13 1/14x18 propeller. Everything seems to run fine at low-medium throttle. I can run it for all day at 50-60% throttle. But if I go 90-%-full throttle I get maybe 1-2 minutes before the alarm starts going off. Waterpump is supposedly new. It is putting out water well at all times and never loses flow. I checked the sensor and seems to be working fine. Overheating at 6000 RPMs.
Anyone have any advice on what to check next? Any help and input appreciated!!
