Troubleshooting & FAQ
How do I know if this Contact Set fits my engine?
This part is for specific 6-cylinder Volvo Penta engines (AQ165/AQ170/BB165/BB170 series, 1968-1978). Verify your model against the compatibility chart and cross-reference your existing part number with those listed in the Part Number Matrix.
What are the signs of failing ignition points?
Common symptoms include engine misfires, rough idling, difficulty starting, backfiring, or a complete failure to start. Visual inspection may show pitted, burned, or corroded contact surfaces.
