Question

i have a 2000 115hp yamaha outboard engine, and the alarm goes off after a few minutes in full throttle. i changed the water pump and stuff, so i'm thinkin the boat store sold me the wrong water pump plate. But not really sure though

Answer 1

overheating. fix it or kill it.

Answer 2

What alarm is it ? most motors have different alarms, could be a fuel starvation alarm,,

Answer 3

Matt, you are asking for trouble by using full throttle. Keep your throttle down to 80% and you will still have 90% of top speed, and your boat and motor will last much longer, and your gas consumption will drop a lot. By staying a full throttle you are destroying your engine.
