Performance & Practical Benefits
With this harness in place, the helm feels more in sync with all three engines because the wiring isn’t forced into awkward paths. Shifts and throttle changes come through smoother, especially when you’re easing into tight spots. It also makes future service less of a chore since the main route is easy to trace. Everything ends up feeling more relaxed and better organized.
