Volvo Penta Ignition Contact Set — Part #243799
Part Number: 243799
Brand: Volvo Penta
Official Product Type: Contact / Switch Kit (Ignition Breaker Points)
System: Distributor Ignition
Diagram Position: Position 2 (Bosch distributor assembly)
Bosch Distributor Reference: 0231178011
This is the genuine Volvo Penta OEM ignition contact set (breaker points) for Bosch distributors fitted to classic Volvo Penta gasoline marine engines. Despite being listed in some catalogs as a "Switch Kit," this is specifically the breaker-point/contact set that sits inside the distributor — not a dashboard switch or battery isolator. Getting the right contact set starts with identifying the exact Bosch distributor on your engine, as several AQ and BB engines were offered with more than one distributor configuration.

Fitment Notice — Distributor Type Matters
Some Volvo Penta engines were supplied with more than one Bosch distributor configuration. For example, AQ130-series engines can list either 243799 or 1306169 depending on which distributor is installed. Always confirm the distributor assembly number before ordering to ensure you receive the correct contact set.

Replace the contact set when inspection reveals any of the following:
- Burned or heavily pitted contact surfaces
- Excessive point wear beyond serviceable limits
- Unstable ignition timing that cannot be corrected

Parts Desk Insights
The most common ordering mistake on this part is confusing it with a dashboard or battery switch — the catalog name "Switch Kit" is misleading. This is a distributor breaker-point set, and it only fits engines with a conventional points-style ignition system. The critical fitment check is the Bosch distributor number on your engine: if your AQ130 shows distributor 0231178011, this is your contact set. If it shows a different distributor, verify before ordering. Customers doing a full tune-up should pick up the distributor cap (841263) and rotor (243903) at the same time — these are typically replaced together on a points-style service.
Technical FAQ
Q: Is this a dashboard switch or ignition switch?
A: No. Despite the "Switch Kit" catalog name, 243799 is the ignition breaker-point/contact set that installs inside the Bosch distributor.
Q: What point gap should I set after installation?
A: Refer to the service manual for your specific engine model. Point gap specifications vary by engine and distributor — do not use a generic setting.
Q: Can I use an aftermarket contact set instead?
A: Aftermarket cross-reference 18-5305 is commonly cited for this application. For best reliability on a marine engine, the genuine OEM set is recommended.
Q: My AQ130 shows two different contact sets in the parts manual — which one do I need?
A: The AQ130 series was fitted with more than one Bosch distributor. Identify the distributor assembly number on your engine to confirm whether 243799 or 1306169 is correct for your application.
