Are you fairly mechanically inclined and patient ? You can do most of this your self.
If this motor has a VRO on it the continuous warning sound at wide open throttle means no oil . but I really need to know what year it is. If this is a vro system it should have a oil tank for 2 stroke oil and you could have a problem with it as well .
Another thing to check is if the water pump is keeping up at high speed is there plenty of water coming out of the weep tube or pee tube if not your not getting enough water to cool the motor and it is running hot .. Now it could be as simple as the fuel lines and is the first place i would start if you are using any thing fuel related from walmart immediately throw it away and stop using it and look into a 100% fuel line and filter change ..
Kentucky is a dumping ground for bad fuel and this includes mixing it with ether or heptane methanol and ethanol this stuff is hell on fuel lines and aluminum . If you do buy a manual DO NOT get a seloc manuals there junk get a full blown dealer manual that has all the info you need to fix your motor those seloc and clymber ( and some others ) manuals are basic fixes taken from the full blown dealer manual and they leave out too much detail .

The boat has a 95 Johnson Fast Strike, it does have an oil reserve and the bulb pumps up firm and uses oil. The horn chart says it is either a fuel restriction or over heating.

I replaced the water pump and the impeller. I replaced the fuel line and bulb with an OMC. I had the carbs rebuilt.

I am just stumped. Starts fine, runs fine wide open for a while, horn goes off and goes into rough idle. Turn it off and restart and it runs fine for awhile then does it again.

I can do some things but other things I am not sure of so I was looking for some help. Not the greatest mechanic there is and am not confident on boat motors.

Check wires, especially grounds, they cause strange things to happen.
