If you have done B.Tech marine engineering from a recognized Institute then you are eligible to seek a job in merchant navy. Clearing JEE Mains is not a mandatory requirement for joining merchant navy.

I would recommend you to enhance your technical skills in your engineering field by joining some short term course which will eventually help you in job selection.
