In keeping with its policy of replacing engines every 10 years, the FDNY has received 70 news engines from Seagrave. The FDNY maintains 198 engines in frontline service on a regular basis. The new Seagrave engines were designed by the FDNY to cope with lessons learned during 9/11. "After Sept. 11, we decided we needed to have pumpers that can draft out of our surrounding rivers, if necessary, because we saw water mains disappear when the twin towers collapsed," said FDNY Asst. Commissioner James Basile. "To do this, we made provisions for the apparatus to carry four lengths of flex hard-suction on the driver side. We also have the capability of having a special intake on the officer's side of the apparatus to draft, as well as an intake in the front bumper.

The new pumpers have six-cylinder Cummins Diesel engines. These are designed to deliver smoother acceleration and more power for operating 2,000-gpm pumps.

To enhance firefighter protection, the FDNY chose Seagrave's Marauder II cab and chassis. The Marauder II cab has a 3-inch rectangular-tube steel sub-frame, with a welded protective cage made of completely enclosed stainless-steel. The crew cab's roof is 8 inches taller and has more room for tools and gear, due to the engine compartment being moved forward.
