Two Finlay Sinclair Smith penalties and goals from Josh Wardle and Offrande Zanzala saw Marine defeat Southport.
A quick start saw Marine take an early lead thanks to their captain Wardle.
The ball fell kindly to the centre half in the penalty area who smashed home emphatically from close range leaving the goalkeeper no chance.
Southport enjoyed large spells of possession after the goal and eventually found an equaliser.
An inch perfect finish from Ted Lavelle nestled into the bottom right corner, past a scrambling Fraser Barnsley who was unable to get a finger on it.
Minutes later, Aaron Pickles took a swipe at Adam Anson inside the Southport area resulting in a penalty to the hosts which Sinclair Smith scored confidently.
A second penalty was awarded to Marine after the restart.
This time Sinclair Smith opted to go straight down the middle with his finish.
After a long stoppage in play due to the injury of Declan Drysdale, new signing Zanzala grabbed Marine’s fourth of the afternoon.
The striker, who had been lively all game, pinched the ball from Pickles on the edge of the area before placing it into the back of the net.
It wasn’t all smooth sailing for the Mariners as Southport clawed one back thanks to a great finish from Arthur Gnahoua.
Despite a minor scare, the hosts were able to overcome their opponents, in an end to end, enthralling and exciting game.
