How to Upholster a Boat Engine Cover

Item # X-HT-300649

In today’s installment of our Speedboat Makeover Series, we’re reupholstering the engine cover of this used Malibu speedboat. You’ll learn a lot of useful upholstery techniques in this tutorial, including how to sew a French seam and how to upholster around tricky shapes and objects like cup holders. Let’s get started on this boat engine cover upholstery project.

Learn how to re-cover a speedboat engine cover.

The first step of reupholstering a boat engine cover is to remove the old vinyl to expose the foam and fiberglass underneath. Once the old vinyl is removed, you need to inspect your foam. If your foam looks like it’s in good shape you can reuse it, but if it looks compromised we recommend replacing it with new Sew Foam from Sailrite.

We’re using EverSoft™ vinyl upholstery fabric for our Speedboat Makeover Series. We chose EverSoft for its high abrasion and UV resistance, mold/mildew resistance and for its unique four-way stretch properties. It’s very easy to contour and shape during upholstery work, stapling and tacking, which makes it a great choice for upholstery projects that have a lot of curves and shaping.

During this DIY boat upholstery tutorial, you’ll learn valuable DIY tips and techniques that you’ll be able to apply toward future upholstery projects, including:

  • How to sew a French seam.
  • How to replace the sew foam.
  • How to install a boat blanket skirt.
  • How to upholster the cup holders.
  • And more.
