As long as Turner keeps the boat out of trouble and among the top placings, Fire Stopping will be celebrating its first win state championship since 2009/10.
But Stenta and crew Gus Williams and Jackson Cranfield go into the deciding heats in good form after taking out race nine in Manly's pointscore series last Saturday.
They led around the first top mark only to lose the lead to Fluid Building (Clint Bowen) by the second lap.
Fluid looked on target for its first win of the season before a near collision with another craft upended the boat
That allowed Holmes Marine to make up considerable ground and challenge Fluid for the lead.
When Bowen lost his tiller as a result of the close encounter, Stenta made his move and eased away for a tight win.
"It was pretty close the whole race and it was only over the last couple of hundred metres we got him," Stenta said.
