Why won’t my MerCruiser come out of gear?

The Smart Interrupt system may help alleviate this issue by momentarily interrupting the engine when shifting.

How does Smart Interrupt reduce strain on the lower shift cable?

Smart Interrupt reduces strain by precisely pausing the engine when transitioning from gear to neutral.

Do I need to bypass my MerCruiser shift interrupter switch with Smart Interrupt?

No, the Smart Interrupt eliminates the need for a bypass by providing an advanced electronic alternative that ensures reliable shifts from gear to neutral without stalling.

Is it compatible with all MerCruiser engines?

Yes, Smart Interrupt is designed for a wide range of MerCruiser and OMC engines. Feel free to contact us if you need specific compatibility information.

FAQ

Got questions? We’ve got answers. If you have some other questions, feel free to send us an email to support@smartinterrupt.com

What is the Smart Interrupt, and how does it work?

The Smart Interrupt is an advanced, patented electronic alternative to traditional mechanical shift interrupt switches. It momentarily interrupts the engine when transitioning from gear to neutral, ensuring smoother transitions and reducing wear on critical components.

Is the Smart Interrupt compatible with my boat's engine?

Yes, the Smart Interrupt is designed to be compatible with a wide range of MerCruiser and OMC engines, making it adaptable for various setups. Please refer to the product details or contact us to confirm specific engine compatibility.

Does the Smart Interrupt improve the overall performance of my boat?

Yes, the Smart Interrupt enhances performance by providing smoother transitions from gear to neutral, reducing the risk of stalling and protecting key components like the lower shift cable. This leads to a more reliable and efficient boating experience.

Does the Smart Interrupt require any adjustments after installation?

No, once the Smart Interrupt is installed, it is calibrated to function automatically and does not require ongoing adjustments. It’s a plug-and-play solution designed for long-term reliability. However, if your engine has a high RPM idle, you may want to increase the interrupt duration to ensure the dog clutch has enough time to disengage.

How does the Smart Interrupt protect key components like the lower shift cable?

By precisely interrupting the engine during gear-to-neutral transitions, the Smart Interrupt reduces strain on the lower shift cable, minimizing wear and extending the lifespan of this critical component.

What makes the Smart Interrupt more reliable than a factory-installed interrupt switch?

The Smart Interrupt is an advanced electronic alternative to traditional mechanical switches, eliminating common failure points like corrosion, wear, and misalignment. Its state-of-the-art design ensures consistent, long-lasting reliability.
