Installation Compatibility

These decals are designed for installation on the cowling surfaces of Yamaha F115 four-stroke outboard engines. The main cowling graphic is sized to fit the standard cowling width of F115 engines, while the individual badges and brand elements are proportioned to match the original factory placement specifications. The decals are compatible with both tiller-steer and remote-control versions of the F115, as well as both standard (20-inch) and long-shaft (25-inch) configurations.

For optimal results, installation should be performed on clean, dry cowling surfaces that are free from wax, oil, or other contaminants that could interfere with adhesion. The decals are designed to conform to the gentle curves and contours of the F115 cowling, and the high-quality adhesive system ensures reliable bonding to the factory paint finish typically found on these engines.

Professional Installation Guide

Surface Preparation Requirements

Achieving professional-quality results with your Yamaha 115HP cowling decals begins with proper surface preparation. The cowling surface must be thoroughly cleaned using a marine-grade degreasing agent to remove any traces of wax, oil, salt residue, or other contaminants that could interfere with adhesion. For engines that have been recently painted or refinished, allow a minimum of 72 hours for the paint to fully cure before attempting decal installation.

The cleaning process should include washing with soap and water, followed by degreasing with isopropyl alcohol or a specialized marine surface cleaner. Pay particular attention to areas around fuel filler caps, vents, and other hardware where oil or fuel vapors may have created invisible residue films. After cleaning, allow the surface to dry completely and avoid touching the cleaned areas with bare hands, as skin oils can compromise adhesion.

Installation Methodology

The installation of these cowling decals requires careful attention to positioning and technique to achieve results that are indistinguishable from factory-applied graphics. Begin by laying out all decal components and familiarizing yourself with their intended positions based on reference photographs or the original decal placement if remnants are still visible.

For the main cowling graphic, use the “hinge method” by applying a strip of masking tape vertically down the center of the decal’s back side. This creates a pivot point that allows you to position one half of the decal accurately, then swing the other half into position while maintaining perfect alignment. The wet application method is recommended for larger graphics, using a solution of two drops of dish soap per quart of water to allow repositioning during the initial placement phase.

Application Technique and Tools

Professional installation requires the right tools and techniques to eliminate air bubbles and ensure complete adhesion. Use a high-quality squeegee with a felt edge to work from the center of each decal outward, applying firm, consistent pressure to expel air and excess application fluid. Work systematically in overlapping strokes, paying particular attention to edges and corners where lifting is most likely to occur.

For curved surfaces and areas around hardware, use a heat gun or hair dryer on low setting to warm the vinyl slightly, making it more conformable to surface contours. Be careful not to overheat the material, as excessive temperature can cause shrinkage or distortion. After initial application, go over the entire decal with the squeegee again, applying additional pressure to ensure complete adhesion.

Post-Installation Care

After installation, avoid exposing the decals to high-pressure washing or aggressive cleaning for at least 48 hours to allow the adhesive to achieve full bond strength. Small air bubbles that may appear during installation will typically dissipate naturally within 24-48 hours as the adhesive cures and the vinyl relaxes into its final position.

For long-term maintenance, clean the decals with mild soap and water, avoiding harsh chemicals or abrasive cleaners that could damage the protective laminate. The decals are designed to withstand normal marine cleaning procedures, including pressure washing at appropriate distances and pressures, once the initial curing period has passed.
