If you are looking to choose between CSE and Marine, then I'd suggest Marine but only when you do it from some good institution. Like IIT Kharagpur offers B.Tech Marine degree and they have good placements also. They have designed the course in such a manner that it caters to the needs of Marine Technology. Otherwise, CSE is also not bad as it always have a scope and IT sector is the largest among all.
