This was a Japanese anime cartoon made by Seven Arts Productions. It was originally shown on BBC1 from 1969 to 1970, but I'm sure it was repeated many times later, only not for at least 20 years!
It was the adventures of a boy who rode on the back of a white dolphin called Splasher. He fought monsters and evil villains and was helped by a mermaid called Neptina. He chewed 'Oxygum' so that he could breath underwater without coming to the surface.
From this website I found out that there were many more episodes than were ever shown in the UK. http://www.alphalink.com.au/~roglen/marine.htm
and that it Japan he was known as Kaitei Shonen Marien (Marine The Sea Bottom Boy).
He worked for the Ocean Patrol Headquarters under the sea, responsible for making the oceans of the world safe. The main patrol boat was the P1, led by Marine Boy and his 2 crew members Piper (the skinny one) and Bolton (fatter with a deeper voice). The sub fired torpedoes and had a chute underneath where Marine Boy would swim in and out. Like all ocean patrol recruits, they wore red berets as part of their uniform. The entire operation was run by Dr Mariner who was Marine Boy’s father, with the help of Professor Fumble (has a huge nose) who comes up with fabulous inventions to help Marine Boy defeat his foes.
