![]() Ie 25 foot Bayliner or XYZ make, inboard to outboard conversion to see what the results were. Or even other makes of similar hull deadrise, beam and weight. If your make of boat has been around awhile, you can search forums and often find people who have done the same thing. Removing the old iron V8 and heavy leg, you may see a drop in weight of maybe 400 pounds, As the old boat was a single, it appears that you are ok with 12 Single Brackets 12 Single Brackets 23 Single Brackets. 30 Triple Brackets Single Engine Brackets. A single larger outboard will be a little better for a lower fuel consumption. 12 Mini Brackets 7 Mini Brackets 9 Mini Brackets Outboard Engine Bracket Accessories Triple / Quad Engine Brackets. The separation between these set ups MAY not be far apart. You are replacing an old carbed V8, which would not have given you good numbersĪnd switching up to EFI outboards, four stroke. You can check out the fuel curves for the Cutwater 30 available with a single DD Volvo diesel compared to the 300 twin Yamaha. Its been a busy year, but its finally time to actually start doing the dirty work to get this project started After running the calculations and many conversations with Keith, I finally have a plan in place to breathe a whole new life into this fantastic hull. Re the hull Many manufacturer's are using the same hull with an inboard configuration as well as single or twin outboards with good success. It would be wise for a technician to study your current boat and the new configuration you want for it. The I / O motors leave much more headroom for the swimming platform. If the boat is designed to achieve its optimum point with current engines, it can be assumed that any other configuration will be less efficient in terms of speed and consumption. The power required will be very similar since the power calculations usually do not take into account the type of engine or its position on board (since, in addition, the direction of the propeller thrust will not change), although it must be considered the overall efficiency of the engine-drive unit, which will undoubtedly change. This will affect the planing conditions, which must be re-studied. Well in this informative show, John will teach you how to completely convert your transom so an outboard motor and bracket are possible. Most importantly, in my opinion, the overall weight of the boat with the new engines is going to change, as well as the position of the CoG. In a quick response, without studying anything or knowing your boat, I think you should take into account several things.
