TLDI® (Two stroke Low pressure Direct Injection) is a powerful direct fuel injection system that reduces emissions over conventional carbureted 2-stroke motors while also greatly increasing fuel and oil economy. With a TLDI® outboard, you get all the efficiencies of a 4-stroke outboard and all of the power of a 2-stroke outboard in one. |

What is the reason for a Direct Injection 2-stroke? | |||||||||||||||||
In 1998, the U.S. Environmental Protection Agency (EPA) issued new regulations governing the emissions of outboards sold in the United States. The purpose of these regulations is to reduce the pollutants created by outboard motors. In short, the EPA regulations mandate that all outboards meet certain emission requirements by the year 2006. Outboard manufacturer’s are using a variety of technologies to reduce the emissions of their outboards including 4-stroke and direct injection 2-stroke technologies. |

I’ve heard I won’t be able to use 2-strokes after 2006. Is this true? | |||||||||||||||||
Absolutely not! The EPA requirements only specify that outboards must meet certain emission restrictions. |

What are the advantages of TLDI® over a 4-stroke motor? | |||||||||||||||||
The biggest challenge facing outboard manufacturers in meeting the 2006 EPA regulations is which technology to use…direct injection (DI) 2-stroke or 4-stroke. Both technologies can be used to meet the 2006 standards and both technologies have significant advantages over carbureted 2-strokes. Most manufacturers are taking a “two-pronged” approach and using a combination of DI and 4-stroke depending on the horsepower of the motor. |

How does the TLDI® compare in weight against 4-strokes?>/a> | |||||||||||||||||
The weight of a 90 TLDI® outboard is quite a bit less than the average 4-stroke. By using existing 2-stroke components and combining them with our advanced TLDI® technology, we are able to create a lightweight outboard that meets all EPA/CARB emission requirements. Not only do you get an outboard that uses our proven 2-stroke block but the weight savings versus a comparable 4-stroke translates into better performance for your boat. |

Why not use TLDI® technology on every model? | |||||||||||||||||
For larger motors, TLDI® makes perfect sense since you get all of the advantages of a 4-stroke and the lighter weight gives the TLDI® models better acceleration and performance over a 4-stroke. One reason the TLDI® technology is not applied to smaller motors is that TLDI® motors have an electronic “brain” (ECU) that controls the operation of the motor as well as electronic fuel pumps. Naturally these electronics must be powered by the motor’s battery. While the TLDI® technology could be adapted to smaller motors, very few users want to use a battery when using a small motor on an inflatable boat or a sailboat for example. |

A high-pressure system forces straight fuel, up to 1000 psi, into the cylinder through the injector. A high-pressure system does not blend air with the fuel, so the droplets of fuel are much larger and do not burn as completely as fuel droplets in a low-pressure system. A less complete burn results in weakened fuel economy and the intense stress of 1000 pounds of pressure can also cause unneeded strain on the motor’s components. |

How good is the fuel economy of a TLDI® motor? | |||||||||||||||||
With the TLDI® system you achieve a dramatic increase in fuel economy over conventional 2-strokes. The TLDI® system will even provide better fuel economy than a comparable 4-stroke while at trolling and cruising speeds. |

What kind of oil do I need to use in my TLDI®? | |||||||||||||||||
You will always need to use a high grade TCW3 oil designed for use in Direct Injection motors. Regular TCW3 outboard oil is not recommended for use in the TLDI® models Most outboard companies offer a high grade/premium TCW3 oil designed for use in Direct Injection motors. The following oils have been tested by our factory and certified for use in TLDI® motors:
The above oil brands are currently the only brands that have been tested and approved by our factory for use in TLDI® systems. |

What is the “User Adjustable Idle Setting” feature? | |||||||||||||||||
A unique feature on our TLDI® outboards is our user adjustable idle speed system. By pressing in on the key switch, you are able to adjust the idle from 700 to 900 RPM’s while you are using your outboard. Our TLDI® system will even remember the last setting and use this speed the next time you use your motor. In areas where currents are stronger or constantly changing, this makes time spent trolling all the more easier and pleasant. And because the TLDI® is a direct injection outboard, trolling for extended periods of time drastically reduces the occurrence of fouled spark plugs. |

Is there any special maintenance required for a TLDI®? | |||||||||||||||||
Unlike a 4-stroke motor, there is no special maintenance required for a TLDI®. We do, however, recommend that you change your water pump impeller every year. We also recommend that you change the compressor drive belt, air filter, and fuel filter every 2 years or 200 hours. Other than that, you follow basic outboard maintenance as outlined in your owner’s manual. |

This is new technology, how can I be assured it will work? | |||||||||||||||||
We thoroughly test new outboards for years before they are introduced to consumers. The TLDI® system was tested for 6 years before being released. These outboards also use the same tried and true components we’ve been using in our conventional 2-strokes for years, giving boat owners exceptional reliability and the utmost confidence in their outboard backed our 3+1year limited warranty. |

What models are currently available and what others are scheduled to come out? | |||||||||||||||||
We currently offer a 40hp, 50hp, 70hp, 90hp and 115hp in a TLDI® version. Over the next few years you can expect to see our TLDI® system incorporated in all of our upper hp outboards from 40hp on up. As each model is scheduled for release, the relevant specifications will be posted to the “Products” section of our website, so be sure and check back often for the latest in outboard technology. |

What is the warranty coverage on a TLDI®? | |||||||||||||||||
We offer one of the best warranty coverages of any Direct Injection outboard available on the market. The 5 year limited warranty covers parts & labor. Our new 5 year warranty, covers all TLDI models sold for non-commercial use from January 1, 2013, for 2011 production models or higher. |

Why should I buy a TLDI®? | |||||||||||||||||
The TLDI® system provides all of the things you need in an outboard. It provides superior performance while providing exceptional fuel and oil savings. A TLDI® outboard produces fewer emissions and meets all federal and state requirements for outboard emission control. At low rpm, vibration is almost non-existent and acceleration from low to high speed is extremely smooth and sharp making the outboard very responsive. Also, the reduction of air intakes from three to one allows much quieter operation. |
