[Water sports]

Can you please Let me know removing the cylinder head to access the waterways beneath, are there seperate bolts holding down the main heads as i dont want that part to become loose resulting to new gaskets etc and is it common for the Waterways to become restricted with sea salt/ corrosion as I'm also wondering if this is a factor on why the main buzzer sounded continuously, just trying to eliminate any problems, I would appreciate if somebody could answer me on this rapidly as I am noticing I am not getting answers to all of my questions however you may be busy answering others or on a holiday break please don't be offended just wanting to ensure there is no problem, if there is any concern or issues on why my questions arent been answered can you please let me know

The same bolts do both parts of the head and you should replace the o-rings.
Typically this area doesn't clog up. THe areas the clog with debris are the cylinders and the lower cylinder drain hoses.
