A lot goes into delivering a solid tune. EFI stands for Electronic Fuel Injection. Essentially, all modern outboards rely on an ECU, a computer, to manage the engine. This allows manufacturers to implement certain engineering solutions, often making minimal variations in engine blocks, pistons, and valves - sometimes none at all. They typically de-tune the lower horsepower models and only make slight hardware adjustments for these more affordable options. Additionally, many outboards are designed to run on 87 octane gas, providing room for enhanced power output.
We research and develop methods to deliver upgraded tuning data to your outboard's ECU, along with easy steps to un-restrict airflow. While there's much more involved than can be detailed here, we can offer these outboard tuning solutions at a low price to you.
How does it work? We provide you with instructions on how to detach your outboard ECU, securely package it, and send it to us. Once we confirm receipt, we'll make a copy of your factory tune data, tune the ECU to your requested horsepower gains, conduct testing, and then return it to you - you click the ECU back in place, take out the air restrictor and enjoy more power on the water!
$500 CAD + shipping. Note that the Tohatsu 9.9, 15, and 20 hp all share the exact same engine, including the block, pistons, and valves. Everything is adjusted through the tuning of the outboard ECU along with a few simple instructions, to un-restrict airflow, we send to you. We encourage you to compare our EFI tuning service with others available in the US, who typically charge around $600 US + shipping for similar tuning services, easily adding up to much more. Additionally, you receive a $200 credit for future tunes on the same platform, for example, if you want to upgrade to 25hp for a bigger boat using the same outboard.
$600 CAD + shipping, as a bit more research and testing has gone into this. With our tuning solutions, it is possible to safely exceed the factory tune of 20 hp for this block. We carefully perform EFI tuning and test on our own hardware to ensure that you are safe on the water. For optimal results, use 89 octane gas with this tune. It’s perfect for launching up on plane in no time, or you can install a higher pitch propeller to cruise quietly at lower RPM.
Please reach out to us, and we will get back to you shortly. These EFI tuning services are currently in the Beta stage, and while we do offer this, it's important to note that these outboards are not exactly the same in hardware in the horsepower range (unlike the 9.9, 15, and 20hp outboards). Therefore, we develop fully custom engineering solutions to reliably pull more power from these outboards. There are huge gains to be had, but do expect to use 89 octane gas for the higher horsepower gains tunes. This is great for impressing your buddies on the fishing trip!
Send us a message with your outboard specs, year, and model, and we will get back to you promptly. We offer competitive pricing similar to that of other outboard brands, but with custom outboard EFI tuning. As a result, the price may vary slightly based on your specific needs.
Mercury 9.9, 15 and 20hp EFI models are actually Tohatsu outboards, with a Mercury cowl and tiller! Reach out to us, and we will help you out.
