Briggs and Stratton 36hp Vanguard 993cc
Briggs and Stratton 36hp Vanguard 993cc engine has been used as the shallow water outboard motor (mud motor) for years. This engine is known for simplicity, durability, and affordability. The stock 36hp engine came with a carburetor which had the shortcoming of a typical carburetor engine: difficult cold start, rough idle, stalls, lack of power, and frequent maintenance. Ecotrons has been supplying an EFI kit to some boat manufacturers to convert this carburetor engine to fuel-injected for 2 years. This EFI kit has been installed on many new Briggs & Stratton 36hp engines. It has been proved to be a solid kit, increasing the engine power, saving the fuel, as well as other EFI advantages. Now Briggs and Stratton has released its own 37hp EFI Vanguard 993cc engine to the market. It is basically the same engine with a factory EFI system. For those who have already owned the carburetor engines, you now have the option to upgrade your carb engine to fuel injected with the Ecotrons EFI kit. This EFI kit includes almost all necessary parts to completely replace the carb fuel system (see below for some adaptation needed). The throttle body and manifold assembly are bolt-on to the engine. It is easy to install for the people who are mechanical inclined. You do NOT need to tune it. You can tune it if you know how to tune EFI. It is a fully programmable EFI system. For those who have the "stage I, or stage II" engines with cam mods, polished ports, shaved heads, and/or after-market exhaust, this EFI kit is a perfect cure for the carburetor related issues. We even have the tuning for stage I or stage II engines ready to ship.
