# NGK Spark Plugs: Evinrude & OMC Outboards ## NGK Spark Plugs: Evinrude & OMC Outboards 293 spark plug applications from NGK's marine catalogue, for the engines we supply parts for. Each line gives the plug NGK specifies, the iridium upgrade where one exists, and the electrode gap. **Check the gap before you fit.** Plugs are not always gapped correctly out of the box, and the wrong gap causes misfire and hard starting. Where a resistor plug is specified, fit a resistor plug — a non-resistor substitute can interfere with a tacho, sounder or engine electronics. - [Evinrude](#evinrude) - [OMC](#o-m-c) ### Evinrude 182 applications Model Engine / details NGK plug Iridium upgrade Gap 1 HP 1 · 1R Standard Ign. · 68→70 B6S 0.8 mm 1.1 HP 1.1 · 46→47 B-4L 0.8 mm 1.2 HP 1.2 · Magneto · 86→90 B6S 0.8 mm 1.5 HP 1.5 · Standard Ign. · 68→70 B6S 0.8 mm 2 HP 2 · 1-Cyl. · 91→98 BPR6HS BPR6HIX 0.8 mm 2 HP 2 · Standard Ign. · 68→70 B6S 0.8 mm 2 HP 2 · 2R Standard Ign. · 71→84 B6S 0.8 mm 2 HP 2 · Aquanaut Diving unit · 66→70 BM4A 0.8 mm 2 HP 2 · Commercial · 00→01 BZ7HS-10 0.8 mm 2 HP 2 · Jr., Colt · 71→90 B6S 0.8 mm 2.3 HP 2.3 · 91→97 BPR6HS BPR6HIX 0.8 mm 2.3 HP 2.3 · 98→99 BZ7HS-10 0.8 mm 2.5 HP 2.5 · 87→88 BZ7HS-10 0.8 mm 3 HP 3 · Lightwin Standard Ign. · 52→74 B6S 0.8 mm 3 HP 3 · 2-Cyl. · 89→97 BR6HS BR6HIX 0.8 mm 3 HP 3 · 99→ BZ7HS-10 0.8 mm 3.3 HP 3.3 · Standard Ign. · 48→51 B6S 0.8 mm 3.3 HP 3.3 · 1-Cyl. · 91→03 BPR6HS BPR6HIX 0.8 mm 3.4 HP 3.4 · Yachtwin · 64→74 B6S 0.8 mm 4 HP 4 · 2-Cyl. · 89→98 BR6HS BR6HIX 0.8 mm 4 HP 4 · 4R, 4W Standard Ign. · 69→76 B6S 0.8 mm 4 HP 4 · Ultra, Excel · 87→88 BZ7HS-10 0.8 mm 4 HP 4 · V4, V4A, V4M, V4S, VX, VXH Standard · 58→67 B6S 0.8 mm 4 HP 4 · Yachtwin · 64→74 B6S 0.8 mm 4.5 HP 4.5 · 80→85 BR6HS BR6HIX 0.8 mm 5 HP 5 · Angler · 65→68 B6S 0.8 mm 5 HP 5 · Dia. 14 mm plug · 90→97 BR6HS BR6HIX 0.8 mm 5 HP 5 · Dia. 14 mm plug · 98→ BZ7HS-10 0.8 mm 5 HP 5 · Dia. 12 mm plug · 4-Stroke 128cc OHC · 97→03 D6HA 0.7 mm 5.2 HP 5.2 · Lightwin · 52→74 B6S 0.8 mm 5.5 HP 5.5 · Incl.

The digit in the middle is the heat rating — a **higher number is a colder plug**, which is the opposite of most other brands. An **R** after the first letters means a resistor plug. Codes ending **IX** are the Iridium IX range, a direct upgrade with a finer centre electrode. A **Y-** prefix is a diesel glow plug, not a spark plug, and has no gap. Do not substitute a hotter or colder plug to cure a running problem. A plug reading the wrong colour is telling you about the fuel, ignition or oil — changing heat range hides it rather than fixing it. ### Other engines - [Mercury](/pages/ngk-spark-plugs-mercury-outboards) - [Mariner / Force](/pages/ngk-spark-plugs-mariner-force-outboards) - [Yamaha](/pages/ngk-spark-plugs-yamaha-outboards) - [Suzuki](/pages/ngk-spark-plugs-suzuki-outboards) - [Johnson](/pages/ngk-spark-plugs-johnson-outboards) - [Tohatsu / Nissan](/pages/ngk-spark-plugs-tohatsu-nissan-outboards) - [Honda / Volvo Penta / others](/pages/ngk-spark-plugs-honda-volvo-penta-outboards) - [MerCruiser inboard](/pages/ngk-spark-plugs-mercruiser-inboard) - [Other inboards](/pages/ngk-spark-plugs-inboard-sterndrive) - [PWC & jet ski](/pages/ngk-spark-plugs-pwc-jet-ski) ### Not sure which plug you need? Model families ran across several specifications and the year or serial usually decides which line applies. Ring [0412 532 984](tel:+61412532984) with your engine and serial number and we will confirm the plug, the gap and how many you need. Our other workshop charts are on the [reference charts page](/pages/resources), and the how-and-why lives in our [boat maintenance guides](/blogs/guides). Applications compiled from NGK's published marine application guide and reproduced here as reference data. NGK's own guide is the authority; always confirm against your engine's manual.
