# 11' Boston Whaler - DIY Overhaul Source: https://www.youtube.com/watch?v=CtaLTcDIy3Q Recap page: https://rapidrecap.app/video/CtaLTcDIy3Q Generated: 2026-03-07T16:31:33.862+00:00 --- ## Quick Overview The owners successfully completed a full restoration and modification of an 11-foot Boston Whaler, including installing a custom center console, adding new rub rail, and mounting the 30 HP Yamaha outboard motor, culminating in a successful sea trial. **Key Points:** - The project involved restoring a 30-year-old 11-foot Boston Whaler, including fixing hull issues like soft foam core. - A custom center console was designed using CAD mockups (04:32) and built from plywood to house the battery and steering components. - The team installed new rub rail (10:11) using heat to shape it, and used Marine-Tex epoxy putty for hull repairs (01:36). - The original steering rod was seized and required being heated with a torch and forcefully removed (08:13). - The final assembly included mounting the 30 HP Yamaha outboard motor and testing the steering linkage (09:08). - The sea trial confirmed the boat was fast and handled well, providing satisfaction despite the demanding restoration work (12:23, 12:38). ![Screenshot at 00:23: The owner discusses the initial purchase of the 11-foot Boston Whaler, which came with a 30 HP two-stroke engine and was acquired for $5,000, highlighting the boat's core feature: its foam core construction.](https://ss.rapidrecap.app/screens/CtaLTcDIy3Q/00-00-23.jpg) **Context:** This video documents the DIY restoration and modification process of an old 11-foot Boston Whaler boat, affectionately named 'The Sound Pounder.' The project involved significant structural repairs to the fiberglass hull, installation of a custom-built center console to accommodate modern components like a steering wheel and battery, and the reinstallation of the 30 HP Yamaha outboard motor, all documented leading up to a successful sea trial. ## Detailed Analysis The video details a comprehensive, budget-conscious restoration and modification of an 11-foot Boston Whaler, which was purchased for $5,000. The restoration began with addressing structural issues, including discovering that the boat's foam core was soft like a sponge (00:45), requiring sanding down the gel coat (01:12) and filling numerous holes with Marine-Tex epoxy putty (01:36). Major mechanical work involved removing a seized steering rod from the 30 HP Yamaha outboard motor using heat and brute force (08:13). The team fabricated a custom center console out of plywood after creating digital mockups (04:33) to house the battery and steering components, opting for a cheaper plywood build over expensive marine-grade wood (04:44). They installed new 60-foot rub rail (10:00) using a heat gun to make it pliable (10:39). The final steps included mounting the steering components and the engine (08:45). The narrator expresses great satisfaction with the outcome, noting that despite the hard work and small budget, the boat performed excellently during the sea trial, running fast and handling well (12:23). ### Acquisition and Initial Assessment - The owner bought a 30-year-old 11-foot Boston Whaler for $5,000 (00:01, 00:37) which had been stored outside for years and sustained hull damage (00:08). ### Hull Repair and Refinishing - Sanded off old anti-fouling paint (01:12); used White Marine-Tex epoxy putty to fill numerous holes (01:36, 01:57), noting the putty hardens like steel (01:58). ### Custom Console Fabrication - Designed a center console using CAD mockups (04:32) and built it from plywood to house the battery and steering mechanism (05:34). ### Steering and Engine Work - Removed a seized steering rod by heating it with a torch (08:13); later mounted the steering hub and reinstalled the 30 HP Yamaha outboard motor (07:20, 08:45). ### Final Assembly Details - Installed 60-foot rub rail using a heat gun to conform it to the hull's shape (10:11, 10:38); noted that the gel coat requires a final coat with wax to cure properly in the open air (02:15). ### Sea Trial and Conclusion - The completed boat performed very well on the water, running fast, handling great, and proving the custom modifications were successful (12:23, 12:38). ![Screenshot at 00:23: The owner introduces the 11-foot Boston Whaler purchased for $5,000, showing an image of the boat on a trailer.](https://ss.rapidrecap.app/screens/CtaLTcDIy3Q/00-00-23.jpg) ![Screenshot at 01:36: The process of mixing White Marine-Tex epoxy putty, a two-part system used for filling holes and structural repairs on the hull.](https://ss.rapidrecap.app/screens/CtaLTcDIy3Q/00-01-36.jpg) ![Screenshot at 03:54: A worker wearing a respirator applies a coat of white gel-coat to the boat's hull in a controlled environment.](https://ss.rapidrecap.app/screens/CtaLTcDIy3Q/00-03-54.jpg) ![Screenshot at 09:08: The owner checks the alignment of the outboard motor's steering shaft against the transom hole to ensure correct positioning.](https://ss.rapidrecap.app/screens/CtaLTcDIy3Q/00-09-08.jpg)
