It is a precision-machined replacement component designed to meet or exceed the quality of the original equipment part it replaces, restoring proper point gap and dwell for reliable spark timing. This contact set is one of the individual components in Sierra's Volvo Penta tune-up kit lineup, alongside the matching 18-5349 condenser and 18-5428 rotor, and is sold here as a standalone part for owners replacing just the points.\u003c\/p\u003e\u003cp\u003eContact sets are a wear item in traditional breaker-point ignition systems, and swapping in a fresh set at regular intervals helps prevent hard starting, misfires, and rough idle caused by pitted or worn contacts. The Sierra 18-5305 is manufactured to original dimensions and mounting geometry so it installs the same way as the OEM part it replaces, with no modification required.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5305\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Contact Set (Ignition Points)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Ignition System:\u003c\/strong\u003e Bosch 4-cylinder I\/O - Volvo Penta\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 243799, 1306169, 243460\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999318725\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eVolvo Penta stern drive (I\/O) applications using a Bosch 4-cylinder ignition system\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e243799\u003c\/li\u003e\n\u003cli\u003e1306169\u003c\/li\u003e\n\u003cli\u003e243460\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5305 fit?\u003c\/strong\u003e The Sierra 18-5305 contact set is designed for Bosch 4-cylinder I\/O ignition systems used on Volvo Penta stern drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-5305 replace?\u003c\/strong\u003e It replaces Volvo Penta part numbers 243799, 1306169, and 243460.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5305 a genuine Volvo Penta part?\u003c\/strong\u003e No, it is a Sierra-manufactured aftermarket contact set engineered to meet or exceed the quality of the original Volvo Penta ignition points it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with part number 18-5305?\u003c\/strong\u003e This listing is for the contact set (ignition points) only; it does not include the matching Sierra 18-5349 condenser or 18-5428 rotor, which are sold separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5305 weigh?\u003c\/strong\u003e The Sierra 18-5305 contact set weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-5305 contact set?\u003c\/strong\u003e It measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5305 work with a different ignition system?\u003c\/strong\u003e The 18-5305 contact set is built specifically for Bosch 4-cylinder I\/O ignition systems on Volvo Penta stern drives; check your engine's ignition system before ordering to ensure proper fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I replace the contact set in a breaker-point ignition system?\u003c\/strong\u003e Contact sets wear and pit over time, which can cause hard starting, misfiring, and rough idle; installing a fresh Sierra 18-5305 restores correct point gap and dwell for reliable spark timing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5305 require modification to install?\u003c\/strong\u003e No, the Sierra 18-5305 is manufactured to original dimensions and mounting geometry so it installs the same way as the OEM contact set it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the Sierra 18-5305 have?\u003c\/strong\u003e The 18-5305 contact set has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5305 part of a larger tune-up kit?\u003c\/strong\u003e Yes, the 18-5305 contact set pairs with the Sierra 18-5349 condenser and 18-5428 rotor as part of a Volvo Penta ignition tune-up, though each is sold under its own part number.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988208890075,"sku":"SIE-18-5305","price":15.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5305_lg__33165.1558128039.500.750.jpg?v=1785188629","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5305-ignition-contact-set-points-for-volvo-penta-stern-drive-replaces-volvo-penta-1306169-243799-243460","provider":"Good Vibes Marina","version":"1.0","type":"link"}
