Miles Rutherford praised his Moneyfields battlers as they twice came from behind to sink Sholing Sports in the Wessex League premier division.
Steve Hutchings hit a brace before Tom McInnes nodded the visitors into a 3-2 lead.
And while Moneys came under late pressure, they held out for a first win of the season.
Rutherford was delighted to see his side get off the mark after defeat to Andover Town on Saturday.
The Moneys boss said: ‘We showed our battling qualities to come from behind to win and that was really pleasing.
‘It was an excellent team performance against a good side.
‘After losing our first game, it showed a lot of character.’
Moneys almost gifted the Boatmen an early goal when defender Jack Lee and goalkeeper Gary Streeter got into a muddle.
Lee sent a headed back-pass behind his advancing team-mate but managed to get back to clear.
The visitors were the brighter of the two teams in the opening 10 minutes – with Conor Bailey twice sending the ball narrowly past the far post.
It was against the run of play when the Boatmen took an 11th-minute lead.
Barry Mason’s corner from the left evaded everyone and ended up in the far bottom corner of the net.
From another set-piece, Bailey headed off the goalline to prevent Moneyfields falling further behind.
And the visitors made the most of the reprieve to level on 41 minutes as Hutchings squeezed the ball in at the near post from a corner.
However, Moneys found themselves behind again five minutes into the second half when they failed to deal with a deep cross and Mason stretched to head past Streeter.
The visitors were coming under sustained pressure and almost immediately Mason fizzed a shot just wide.
But two goals in as many minutes turned the game on its head.
Hutchings brought the teams level for the second time in the 66th minute as he volleyed home Alfie Rutherford’s cross from the left.
And within a minute, Tom McInnes glanced a header into the far corner to put the Copnor club in front.
MONEYFIELDS: Streeter, Da Costa, Inskip, Lee, Cook, McAuley, Rutherford, Raine, McInnes, Hutchings, Bailey. Subs: Cotton, Pennary, Giddings
