Troubleshooting & FAQ

How do I know if this solenoid fits my Volvo Penta engine?

This solenoid fits specific Volvo Penta diesel engines that use a Valeo-style starter. The best way to confirm is by matching your old part's number to one of the cross-reference numbers listed in our Part Number Matrix, such as 859618 or 859618-1.

What are the common signs of a failing starter solenoid?

Symptoms include a single, loud "click" when you try to start the engine, the starter motor spinning without engaging the engine (freewheeling), or no response at all. Intermittent starting is also a common sign of a failing solenoid.

Can I install this myself?

Yes, installation is straightforward for those with basic mechanical skills. It involves disconnecting the battery, removing the old solenoid from the starter, and bolting on the new one. However, we recommend professional installation if you are not comfortable working with your boat's electrical system.

Is the unit sealed for marine use?

Yes, this solenoid is designed specifically for the rigors of the marine environment, with construction intended to resist moisture and corrosion common in saltwater and freshwater applications.

What's the difference between this and an OEM part?

This is an aftermarket part built to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It offers comparable performance and durability at a better value.

Why does the starter click but not turn over the engine?

A clicking sound usually means the solenoid is receiving power and trying to engage the plunger, but there isn't enough power to turn the starter motor, or the solenoid contacts are worn. First, check your battery charge and cable connections. If they are good, the solenoid itself is the likely culprit.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
