carburetor problems mariner 90 4 stroke

[Chasers]

Repairing an engine, a mariner 90 4 stroke, 2001, and have come across ceased Carburetors. the bottom one has been semi submerged in salt water, ceasing butterfly totally. other 3 after soaking in diesel for four days have slight play in the butterfly.
i need one new carburetor for certain, the other 3 are hit and miss at the min. been informed theres a chance that a carb repair kit (at £250 a piece!) may solve the issues, chances may be that the injectors may still clog! its a dear risk! also been informed that an ultrasonic clean may do the trick. and even alloy wheel cleaner!
new carbs are priced at £450 approx per piece and thats a pricey rebuild.
Does anyone have any second hand carbs lying doing nothing?!?!?
or know of any?
or happens to have four new ones you want to get rid of? for cheap!!!
a Yamaha F100 carbs are also compatible.
any form of help really appreciated guys and girls.
location not important.
many thanks
happy ribbing

If its got fuel injectors, aren't the things with the butterflies in throttle bodies not carburettors ??
Or is it that the jets may clog ? in which case it has carbs,
sorry to be pedantic
