*Note:
- Working times listed above are the average window for applying, assembling, and adjusting when mounting the Wedge Pack with adhesive.
- Adhesives also have fixture times that must be honored when considering how long to wait before mounting the Actuator.
- Each adhesive has a full cure time or close to full cure, which must be met before any load is applied. After the installation is complete, before sea trialing the boat, wait at least the full cure time advertised by the adhesive manufacturer in the temperature during the install, or 24 hours, whichever is greater.
- Temperature will greatly affect all of the times mentioned above. Warmer temperatures reduce working time. Colder temperatures increase fixture time and cure time. (In very cold climates, the adhesive may need to cure for multiple days before sea trialing.)
- Refer to technical data sheets (TDS) and manufacturer recommendations for the particular adhesive being used.
Quantity:
| Controller Size | Minimum Adhesive Quantity (per boat) | Minimum Adhesive Quantity (per Transom Plate) |
| 450 mm | 900 ml | 450 ml |
| 525 mm | 1050 ml | 525 ml |
| 600 mm | 1200 ml | 600 ml |

Approved two-part adhesives come in multiple mixing ratios – 1:1, 2:1, or 10:1. Use the correct dispense gun and mixing nozzles for the adhesive type. Failure to do so will result in poor adhesion and will void the systems warranty.

WARNING: Check the adhesive being used to verify it is compatible with the hull material (epoxy resin fiberglass, polyester resin fiberglass, gel coat, etc). Some require a primer when used with certain materials. For example: Plexus primer must be used if performing an aluminum hull installation with Plexus MA590.
