Bowen’s deflected strike is the difference between the two sides as West Ham United move back into fourth for the time being.
The Hammers will have to wait for Manchester United’s game to finish to find out if they will remain there.
But they have done their bit after a scrappy game at the London Stadium.
West Ham had to wait until the 68th minute to find a way past Watford’s stubborn defence.
And Bowen’s shot took a wicked deflection off Samir, which gave Foster no chance in goal.
Foster did well to keep his side in the game on two occasions, denying Benrahma and Bowen.
Whereas Hodgson’s men did not do enough to trouble Fabianski, with Cleverley coming close from the edge of the box.
Hodgson’s side still has work to do in the final third if they want to avoid the drop, but he has got them playing for him.
Hodgson tastes defeat for the first time as Watford boss, but he has undoubtedly made them hard to beat.
Without a lucky deflection, the Hornets would be travelling home with a share of the points.
WEST HAM (4-2-3-1): Lukasz Fabianski;
Vladimir Coufal, Craig Dawson, Kurt Zouma, Aaron Cresswell;
Tomas Soucek, Declan Rice;
Jarrod Bowen, Said Benrahma, Pablo Fornals;
WATFORD (4-4-2): Ben Foster;
Kiko Femenia, Craig Cathcart, Samir, Hassane Kamara;
Juraj Kucka, Moussa Sissoko, Edo Kayembe, Tom Cleverley;
Emmanuel Dennis, Josh King.
1-0. Bowen fires the Hammers into the lead, although the home side gets a colossal stroke of luck in the process.
The Hammers winger picked up Lanzini’s cross in midfield before dribbling his way to the edge of the box.
His left-footed strike looked tame, but it clipped Samir on the leg, and the deflection sent Foster the wrong way.
