Fiberglass Repair on a Yamaha WaveRunner

By Jordan Teddleton

I wanted to purchase a personal watercraft so I’d be able to join my friends at the local lake for some fun in the sin this summer.  Like most people on a budget, I searched Craigslist for the best deal.  I needed something low maintenance, so a WaveRunner™ felt like a good fit.  After a week of looking, I found a 2004 Yamaha GP1300r that appeared to be in decent shape; however, a strangely placed sticker on the top port side turned out to be covering a painful past.

Triple Threat, 38 years old and counting

A case study in remediating gelcoat blisters

By Bruce Niederer — GBI Technical Advisor

My father, rest his soul, and I bought Triple Threat together sometime in the mid-’80s. We raced our ’81 Pearson Flyer hard together for the next 15 or so years, including 12 Port Huron to Mac races. The purchase date is lost to history, but the details surrounding how many times the boat needed a new bottom—meaning a new epoxy barrier coat—are forever etched in my psyche. It’s all the sanding that accompanies repairing gelcoat blisters that has addled my IPA soaked cranium. One just doesn’t forget those seemingly endless hours of self-imposed torture.

J22 Hog Tide at the Gougeon Brothers shop for her deck repair.

Hog Tide Deck Repair

By Greg Bull — GBI Technical Advisor

Hog Tide’s deck was spongy around the chainplates, so I decided to fix the core in the deck. Because the main bulkhead was being replaced, it made it easier to do the deck repair from the underside. I started by removing the inner laminate to get to the bad core. I determined the extent of the bad core by tapping on the laminate; a duller sound suggests deteriorated core. Another way of determining if the core is bad is to drill small holes to see where the bad core is by noticing if the balsa core is a dark color. Water may even drip from the drilled holes. To cut the inner laminate I used a high-speed oscillating cutter with a diamond grit blade (multitool). When cutting out the inner laminate, keep the area that is being opened up as small as possible. You can always make more cuts to make the area larger. Continue reading

Cockpit Sole Repair

By Don Gutzmer – GBI Technical Advisor

As a technical advisor, part of my job is to guide our customers to the correct product selection and discuss proper repair procedures. Sometimes it’s a fun challenge to take on my own projects to stay busy, and it helps me learn what my customers are up against when they do similar projects. This project was repairing the cockpit sole (floor) of a 1994 Four Winns 190 Horizon. The pictures will help tell the story. Continue reading

Sea Ray 400 Seat Repairs

By Sam Magruder

I have a 1996 Sea Ray 400 Express Cruiser that I purchased in April 2014. The vinyl is in excellent condition in the cockpit. However, when someone sat in the front passenger seat (45″ wide) the back looked like it wasn’t attached. I went to the Sea Ray Owners Club website to explore the repairs and a fix for the seat. I learned that if I waited until the seatback broke, the vinyl would be damaged, and it would be costly to replace. Continue reading

Hog Tide Project

By Bruce Niederer — GBI Technical Advisor

The Hog Tide project began last summer when we partnered with Sail Magazine to produce a series of short videos showing how to repair an older J22 that I had arranged to be brought into the GBI Tech shop. The boat, named Hog Tide, needed the types of repairs we wanted to cover. The videos of the Hot Tide project can be found at both westsystem.com and sailmagazine.com. Continue reading

Techniques for Fiberglassing Overhead

By Tom Pawlak — GBI Technical Advisor

The prospect of fiberglassing overhead when laminating the bottom of a hull can be a bit ominous. Any type of overhead work can be frustrating, but the thought of trying to hold fiberglass in place while applying epoxy can produce nightmares for some people. This is especially true if you will be working alone. Continue reading

Profile of an American Craftsman

By Bruce Niederer — GBI Technical Advisor

I hear it said increasingly often in the last couple of years as I meet people during my travels “Who will be the next generation of tradesmen? Who is going to work on our cars, boats, and homes?” This is a serious lament posed by today’s tradesmen, potential employers who have a very hard time finding apprentices and workers to learn their trade. The U.S. is in dire need of men and women willing to work with their hands and develop the skills necessary to build and repair all our…stuff. Continue reading
