The present invention relates to a plug for covering a seawater inlet port, which can block a leak between a fixing bolt and a fastening hole formed in a cover member due to hydraulic pressure during the use by closing a gap between the fixing bolt and the fastening hole with the elastic plug. The plug includes a cover member blocking the seawater inlet port formed in one side of a lower portion of a hull and including an outer plate, and fixing bolts penetrating the fastening holes formed in the outer plate of the cover member to press-fix the cover member to the edge of the seawater inlet port. An elastic plug is interposed between the fastening hole and the fixing bolt to block the gap therebetween. |
