Perko makes marine lights, electrical switches and boat hardware. The range here covers navigation lights for bow, stern, side and masthead positions, battery switches, deck fills and deck plates, and hardware such as latches, locks, cleats and rod holders. Listings carry the Perko part number, so a replacement can be matched to the number on the part you are taking off.
Navigation lights
Lights are listed by position and mount, including the bi-color bow light, the 36 in. replacement stern light and the masthead / all-around light. Side lights come in black, white and chrome and in horizontal and vertical mount.
Battery switches
Switches include the battery selector switch, the on-off battery switch and the compact battery switch, along with a battery switch with lock.
Deck fills, latches and hardware
For the deck there are the gas fill with vent and the water deck plate for hose, and for doors and hatches the flush lock and latch. Rod holders, a cleat pair, a step pad and a bronze thru-hull are listed too.
Which navigation lights does my boat need?
It depends on the boat's length and type. The usual set for a small powerboat is red and green sidelights, or a bi-color bow light, plus a white all-round light. Check the current U.S. Coast Guard navigation rules for your boat.
What is the difference between a selector switch and an on-off switch?
A selector switch chooses between two batteries, both, or off. An on-off switch connects or disconnects a single battery circuit.
Will a replacement pole light fit my existing base?
Pole lights plug into a matching base, and the pin layout and pole length have to agree. Compare the part number and base type on the listing with what is on the boat.
Are gas, water and waste deck fills interchangeable?
No. Each is marked for its use, and fuel fills are built for fuel systems. Order the fill that matches the tank it serves.
