Just sprucing up the interior, updating the electronics and maybe adding a new paint job isn’t enough when you are trying to take a classic like the 31 Bertram and breathe new life into her. Richard Mastry of Mastry Engine Center in St. Petersburg, Florida recently took us on a ride down memory lane with one of his passions-- repowering beautiful old Bertrams. He has repowered over 30 of them, so we would call him a pro and since he helped bring Yanmar marine engines into the US, he could also be considered a professional resource for repowering a boat with Yanmar engines. This particular model has been repowered with twin Yanmar 6LPA-STP2s.
