As long as the bilge is deep enough to hold a few gallons of sea water it shouldn't be a issue.. I used to pull my thru hull to clean the paddle wheel and would swap the blank plug in its place.. clean the paddle wheel then remove and replace the blank with the freshly cleaned wheel. It never was more than a couple gallons to do the entire process.
