Upgrading my Tohatsu Outboard from 15HP to 20HP - ECU Upgrade & Restrictor Plate Removal

In this video, I take you through the process of upgrading my 2022 Tohatsu 15hp MFS15E outboard motor to a powerful 20hp using the MFS20E ECU and restrictor plate removal. If you're a boating enthusiast, this is a must-watch!

It seems that the 9.9hp, 15hp, and 20hp EFI models from Tohatsu share the same engine components? In this video, I'll show you how to unleash that hidden power by making these upgrades. You can cross-reference the parts catalogue to see for yourself.

If you have a Mercury Mariner outboard, don't worry; this process should be very similar, but it's always a good idea to consult with an expert if you're unsure about any step.

A word of caution: This upgrade may void any warranty, and it's important to note that I'm not a mechanical expert. So, perform these modifications at your own risk.
