Boaters know that every season launch or repair brings the question: is everything functioning smoothly? For those with a MerCruiser, testing your shift interrupt system is crucial—but with traditional systems, it usually requires launching the boat to apply prop pressure. The Marsden Smart Interrupt changes that. This innovative solution allows you to test your shift interrupt out of the water, making it easier than ever to verify smooth shifting, all from the safety of dry land.
