      A:

      I'm happy to help, Dave! Both of the spark plugs are copper core, resistor plugs with nickel center and ground electrodes. Both center electrodes are 2.5mm. NGK Part No. BPR6EFS (Part No. 3623) has a thread size of 14mm, a hex size of 5/8" (16mm) ,a reach of 17.55mm (.691"), a tapered seat, gap of .032" (0.8mm), a heat range of 6, a removable nut terminal, a thread pitch of 1.25mm and is projected.

      NGK Part No. BR6ES-11 (Part No. 3824) has a thread size of 14mm, hex size is 13/16" (20.6mm), a reach of 19mm (3/4"), has a gasket seat, a gap of .044" (1.1mm), a heat range is 6, a solid terminal, a thread pitch of 1.25mm and is non-projected.

      I suggest following the recommendations of NGK for the proper spark plug for your application, if you could please provide additional information, such as whether this is for an inboard or sterndrive and the production number of the engine.
