Paul Cox resigned as Torquay United manager on Friday
Managerless Torquay suffered their biggest home defeat for almost 20 years as Bromley won 7-3 on their first league trip to Plainmoor.
James Hurst gave the Gulls an early lead before Moses Emmanuel scored a hat-trick in 22 first-half minutes.
Tyrone Marsh made it 3-2 just before half time, but Bromley ran riot in the final 30 minutes.
Goals from Jack Holland, Louis Dennis, Anthony Cook and Ali Fuseini made it 7-2 before March got his second late on.
The last time Torquay suffered such a large home defeat was in October 1995 when they were beaten 8-1 by Scunthorpe United.
The result comes a day after manager Paul Cox resigned, with his assistant John Ramshaw and director of football Dean Edwards taking charge of the team.
"In being involved in football for a lot more than 50 years that's probably the worst defensive display I've ever seen," Ramshaw told Golsicilia.it Radio Devon.
"It's certainly the worst defensive display I've ever seen from a team I've been in charge of."
