Kermorgant shrugged off an early knock to his ankle to play his part in destroying relegation-threatened Birmingham and edged the unfancied Cherries closer to the play-off places.
Winger Matt Ritchie scored one and nineteen goal hit man Lewis Grabban added a brace as Bournemouth toyed with the Blues in the first half before defender Ian Harte scored a fourth after the break.
Kermorgant's slide-rule pass led to Grabban's second from the spot after Darren Randolph recklessly brought down the striker in the box.
Former Charlton striker Kermorgant, 32, then said:
"We want to be in the rush towards the end - and why not? There's less pressure on our shoulders than maybe Reading, QPR or Brighton who are expected to be in the top six at the end of the season.
"We can create momentum with no pressure if we play every game as we are at the moment. They have pressure, we have no pressure. It could be like Blackpool a few seasons ago. Never been in the play-offs, but got there on the last day and then won them."
And Kernorgant is so impressed with boss Eddie Howe, he is even looking to move his family to the south coast. He revealed:
"We live in London at the moment, but I'm hoping to buy a house down there. It's such a good club and a lot of that is down to him. He's young as well - only a few years older than me. But that's good because football is different to the way it was ten years ago and he can relate to it. Sometimes you get older managers who want to play the game the way it was played twenty years ago."
Substitute Federico Macheda, 22, pulled back two second half goals, but the Manchester United loanee said:
"I'm happy with the goals, but not happy about the result because the most important thing was that we won.
"We can't understand why we're so low in the table, but that's the reality right now and we've got to stick together and try and win games."
Under-fire Birmingham boss Lee Clark was more concerned with a boot than the sack after winger Jordan Ibe's footwear malfunction left his team one player short for Bournemouth's opener.
Clark was unhappy with his back room staff and complained:
"I couldn't believe how long it took to get the lad back on.
"I'm not blaming the officials because the laws of the game say if it's equipment then the game has to stop before he comes back on. What I need to ask is should my player have come off and, if he did, should we not have been quicker in getting a replacement boot to him?"
Howe was not getting carried away, but admitted:
"We scored four in midweek and five against Doncaster. There are good signs going forward. It was a really good first half for us."
Grabban scored twice in the midweek 4-1 demolition of Leeds and then served up more of the same to punish the woeful Blues.
Bournemouth moved to within five points of the play-offs, but boss Howe played down his team's chances and said:
"I still think it's going to be difficult. You look at the sides above us and their destiny is in their hands not ours.
"We've had a good month. On paper it was tough with a lot of away games, but we've scored a lot of goals and we look a lot more confident."
Grabban even had a hand in Bournemouth's thirteenth minute opener when he floated a cross over from the right for winger Matt Ritchie to volley in his sixth goal of the season from a tight angle.
Former Millwall hit man Grabban netted his first seven minutes later.
Midfielder Harry Arter set Marc Pugh away down the left and the winger's slow cross deflected off Chris Burke and away from helpless keeper Darren Randolph to leave Grabban a simple tap-in at the far post.
But Randolph was fully to blame for Grabban's nineteenth goal of the season from the spot in the 28th minute.
Kermogant left the Birmingham defence flat-footed to pick out co-striker Grabban in the box and Randolph dived at his feet to up-end him with the ball long gone.
Veteran Ian Harte then turned back the years to add a fourth seven minutes after the break as they continued to dominate.
Former Leeds full back Harte, 36, drifted past static midfielder Callum Reilly on the right and curled his first goal of the campaign into the far top corner of Randolph's goal.
Manchester United loanee striker Federico Macheda then netted two himself as Birmingham eventually woke up.
Winger Jordan Ibe nodded down Reilly's cross in the 57th minute and first half substitute Macheda buried a low shot from twelve yards.
In the 73rd minute Macheda scored his seventh goal since joining the Blues in January, when he drilled in a twenty yard volley to leave keeper Lee Camp stranded.
Birmingham could have been more than three goals down at half time.
Ritchie and Grabban both came close shots that flew just over the bar.
And in the second period Ritchie fired an angled shot narrowly wide of the far post while Randolph had to prove his true worth to beat away a fierce drive from Harte.
Birmingham were jeered off after slipping closer to the drop zone and manager Clark fumed:
"All the goals were poor from our point of view - all preventable. Even the penalty was caused by us. We got the ball taken off us for making the wrong decisions.
"We were poor defensively throughout the side. I'm not only blaming the defenders. It looked like we didn't do what was necessary."
