Product Details

The Blue Sea Systems 2018 Dual PowerPost provides a termination point for extending the length of outboard harnesses or other conductors. Designed specifically for outboard engine installations when factory cables need to be extended, this connector features a unique dual-stud configuration with one 5/16"-18 thread stud and one 3/8"-16 thread stud.

Key Features:

  • Designed for connecting high amp conductors
  • Includes one black and one red insulator for terminal protection
  • Barrier between stud terminals prevents accidental shorts
  • Rated for maximum 48V DC
  • Mounts with #10 (M5) fasteners (not included)
  • CE marked for safety compliance
  • Constructed from durable reinforced thermoplastic base material

This PowerPost connector provides a solid, vibration-resistant connection point ideal for marine, RV, and powersports applications where high-amperage cable extensions are required. The amperage capacity flows between terminals stacked on the post and is determined by the wire gauge and terminals used. The included red and black insulating boots protect terminals from accidental contact and environmental exposure.

I just received my Knn filter. Shipment was on time. The box look beat up and deformed with a lot of tapes but the filter seems to be in good condition.

Good

Easy to search and find parts.

Safe, quick,and easy... thanks.

Made a hard to find part easy.When I received the part it looked like a return from the tape job on the box. Part looked new but handled in an attempted install way of appearance. I'm sure it'll be fine.
