Based on 540 ci , the 825 EFI utilizes a single intercooled 3.3 liter Whipple supercharger for unsurpassed power and driveability . With stock- like idle quality, no one will ever know how much power you have until you pass them. With a Merlin III block as its base, the 825 EFI uses the same quality parts found in the 1200EFI. When combined with its low 5400 rpm peak, the 825 is virtually bulletproof. Available in any custom color of choice and loaded with tons of billet accessories, the 825EFI may be serviced by any qualified Mercruiser mechanic.. The 825 EFI comes standard with a 6 month warranty, but longer warranties are available.
