Measure before choosing guide-ons
- Measure frame width and height at the intended mounting point. Check room for U-bolts, the lights and the hull when loaded.
- Choose a design that touches the hull only as the guide maker directs. Confirm fresh, salt or brackish-water approval for the exact finish.
- Use the trailer’s bow and transom restraints for transport. Guide-ons assist alignment during loading.

Frequently asked questions
Should I choose posts, rollers or bunks?
Use posts when you mainly need visibility, rollers for compatible rolling contact, and padded bunks when the approved setup needs broader contact.
Can every zinc-coated guide-on be used in salt water?
No. Check the exact maker instructions. Extreme Max specifies freshwater only for model 3005.2184.
Do guide-ons secure the boat during towing?
No. Follow the trailer and boat manuals for the bow and transom restraints.
