o2 sensors

[Mxgirl1]

if it keep flushing with salt termiantor over a period of time will the o2 sensors be ok. i habe had them replaced before which i have no problem with doing that. but i believe its due to lack of flushing and salt water. if i intermittently keep flushing my starboard engine do u think it will correct the 02 sensor? also i have rotax 250 4 tec. is the spark plug number DCPR83? 2017 scarab wake impulse edition

Your spark plug should be DCPR8E. If you boat is used in salt water, you must/should flush after every use. Salt corrodes everything.

yes thats the plug and yes i know about flushing. my question was... if there is salt on the 02 sensors and i continue to flush with salt termintor will it clean it off so i can have my full throttle power back. or should i just change the sensors

Salt should never be on the O2 sensor, if salt or even water is on it you have a leak somewhere in the exhaust.

When flushing, be sure to start the engine first, followed by turning on the water source. After 2 minutes, turn off water source and then turn the engine off. After cleaning the boat or after 5 minutes, restart the engine for 5 seconds (no water). This is to expel remaining water from the exhaust.

No, It's not hard at all. But, you'll need to have a special socket (has a slot for the wire to pass thru) to remove and tighten them as shown below.

Doesn't Water flow thru the Cats thus cooling the exhaust?

Water flows in water jackets in the cat. but is not mixed with the exhaust until after the cat.
