Your Outboard Is Peeing Strong—and It Can Still Be Overheating

Your outboard is producing a strong, steady stream of water, so the temperature warning light stays off—and yet the engine may still be overheating. In this video, we explain why the tell-tale stream is only one small part of an outboard’s cooling system. You’ll learn what the pee stream actually confirms, what it cannot tell you, and how blockages, failing thermostats, damaged water-pump impellers, restricted intake passages, faulty pressure relief valves, and internal corrosion can allow dangerous hot spots to develop inside the engine. We’ll show you the warning signs many boat owners miss, including steam, unusual smells, loss of power, rough running, discoloured paint, alarm activation, and an engine that runs normally at idle but overheats under load. You’ll also learn how to inspect the cooling system safely, when to replace an impeller, why flushing with fresh water may not solve the real problem, and when continuing to run the engine could turn a small cooling fault into an expensive rebuild. Whether you run a small fishing boat, a family runabout, or a larger offshore vessel, this guide will help you understand what your outboard is really telling you—and what it may be hiding.
