Seven Marine 657 Weight

And other things you need to know about the Seven Marine 657

When it comes to elite motors, none is quite so well known as the Seven Marine brand. The brand, known for its power and precision, is commonly associated with the larger cruisers and mini-yachts. The engine has even found its place in the smaller angler vessels such as the Yellowfin and some Boston Whalers (post market additions for the most part). In terms of the power, the Seven Marine has become a standard for powerful fishing. It only takes two outboards to really make a center console move across the water. With all this in mind, it is no wonder that the 657 has stirred up a buzz in the boating community. How big is it? What is the power? And where can I find a boat with one? All these we will answer. Here is what you need to know about the Seven marine 657.

What is the weight of the Seven Marine 657?

657 is 1100-1200lbs according to direct communication with Seven Marine. The 1100 pounds is per engine and is based upon the dry weight. The 1200 is an estimate for the weight after the fuel and lubrication and such necessary external elements are added to it. The weight is identical to that of the 557. That being stated, those who are not accustom to the engine should have the beam as well as the engine mounts checked on their boat prior to purchase. These are huge engines with substantial power. They are also rather expensive, so you would not want to damage the boat or the engines by mounting them on a boat which cannot support the weight.

It was advised that those seeking to purchase the Seven Marine have a boat with at least a 2500lbs weight limit. If you are intending on upgrading from another brand of engine, then you should consider the poundage per propeller. Should you have a 2-4k per propeller then you will need to stick with the Yamaha or the Mercury engines. However, if the boat can handle the 4k to 15k per propeller then the Seven Marine is for you. As Seven Marine stated “it is about the balance of the value to the balance of the performance.”.

What is the power of the Seven Marine 657?

The real difference between the 557 and the 657 has to do with the power and the torque that you can find on the new engine. The 557 has 5400 RPM. The 657 offers about a thousand more RPMs on the same weighted engine. In theory, the engine has been optimized with better engineering and technology to rev it up a bit without sacrificing the weight and power that the 557 had. The Seven Marine 657 has revised the cylinder heads and the camshaft, uprated the fuel-injection system, and revised the ECU calibration of its predecessor to give more power and stability to the motor.

Potential boat owners should keep in mind that the updated power means updated casings. Depending upon how fast you wish to go will determine the casing as some have a threshold of 80mph and other can get into the hundreds of mphs.

Where can I find a boat with a Seven Marine 657?
