Whether you're swapping out old throttle cables or installing new controls, getting the right cable length is key to smooth, reliable performance. Ordering the wrong size can lead to frustrating installs and performance issues — not to mention lost time and money.
Here’s a quick guide based on the industry-standard method to help you measure throttle cables like a pro.
🔧 What You’ll Need:
-
Tape measure
-
Pen and notepad (or phone)
-
A general idea of your boat's rigging route
🧭 Step-by-Step: Measuring Your Boat’s Throttle Cables
1. Start at the Control Head (Helm Side)
Find where the throttle cable connects to your control box — that’s your starting point. From there, follow the intended route down through your console or helm station and along the boat’s rigging path.
2. Route Through the Boat
Measure the path along the gunwale, through rigging tubes or chase paths, back to the outboard engine. Be sure to follow the natural rigging route, including bends or turns, and avoid taking any shortcuts.
3. Stop at the Throttle Connection on the Engine
Measure all the way to where the throttle cable connects on the outboard. Add a little extra length if you have a jack plate or plan to tilt your motor frequently, this gives the cable some room to breathe.
📏 Standard Cable Measurement Formula
Once you’ve measured the full routing distance in inches, divide the total by 12 to get feet. Then, round up to the nearest foot, throttle cables are typically sold in 1-foot increments.
Example:
If your measured route is 176 inches:
176 ÷ 12 = 14.67 feet → Round up to 15 feet.
✅ Pro Tip: Always Round Up
Too short = tension, binding, and cable wear.
Too long = no big deal — you can coil excess slack in the rigging.
