Constant beeping noise on my boat?

so i had a problem with my boat a couple days ago, it was not shooting out water where it normally would to indicate that it was cooling itself, and there was also this beeping sound coming from just under the steering wheel. I looked at the intake on the cooler and sure enough there was seaweed blocking it, i

so i had a problem with my boat a couple days ago, it was not shooting out water where it normally would to indicate that it was cooling itself, and there was also this beeping sound coming from just under the steering wheel. I looked at the intake on the cooler and sure enough there was seaweed blocking it, i cleared all that out and started it up again and it was shooting out water like normal, but there is still this constant beeping noise, i also checked the oil and that is cycling just as i

The warning buzzer is temperature activated and could just be a bi-metallic strip that has got old and tired and wont bend back again to break the contact now that it is cooler . Or it could be a push-button type that needs to be reset into the " Green " position . That might be hidden away .
The warning is there for a reason and worked in your case because you checked to find the problem and rectified the blockage , so be very happy , you saved on a wrecked , seized motor !
If you cant find and fix it , then get a marine engineer to call ( problems like this is why they were invented ) and do it for you AND show you how to do it for next time .
And handwrite those instructions out with a sketch of the bits , and staple them into the back of your engine handbook , because you are a human and will forget .

Oh and you HAVE checked your Oil Level is good still ? and that it looks and feels good between your fingers , nice and sticky and oily looking , not thin , burnt black and gritty feeling ?

Read the manual, look for a warning light.
If there's no manual, look for one for the engine online.
On my boat I put a sonalert across the oil pressure warning light so it warns me when it's low on oil.

It could be something totally unrelated – a VHF radio or kid's toy that's got low battery, hidden away somewhere.

Harry Buttcrack:
That beeping is an overheat alarm, and depending on what type of engine you have, it may need to be reset. Year and model of your outboard, please.
landfall43:
maybe the oil level is just too low.

find the beeper and unplug it, its on there just to annoy people.
