I have a 225 yamaha ox66 buzzer is going off

[Blazer210]

The problem I am having with it is, I was out fishing one day and I bumped a stump getting small chunks of wood to get into m L/U causing my overheating alarm to sound off. I took it home pulled the foot off of it and ran water through everything.Still as soon as i get it on plane the buzzer comes on not allowing me to go anywhere. Next thing I am doing is replacing the waterpump and the housing that comes with it. Should I also pull the heads just to see if any passages are blocked? things I have done....

1) pulled the foot off and and made sure it was all fine
2) took poppit valve out ran clean water through it.
3) replaced fuel pump relay $254.00

What would you guys suggest I do next?

Are you sure it is an overheat alarm and not low oil level?

[Blazer210]

well it stays on until the engine sits for 15 to 30 minutes. Then the buzzer goes off,then it will do the same thing.

time does not mean a hole lot to me.
Doesn't it have any indication on the tach or other gauges?

I would start testing things to see what you find

check oil level on main tank when this happens

for cooling system:
replace pump and housing
stats
PRV
check intake grates

I think i found the problem. I took off both thermostats ran water through the ports, and alot of grass and sand came out. I started the motor back up and it didn't set the alarm. So hopefully I found the problem. I will know when I take it out this saturday. Thanks for the help so far

That was the Problem the entire time. I feel like a big dummy,I should have checked those before.
