I have a related (sort-of) question that I’ve been meaning to start a new thread for. That’s probably better…..but I’ll give it a shot here….
Are all tell-tales equally indicative of whether or not the engine is getting proper cooling? Are some engines (due to the placement of the tell-tale outlet) going to spit water (assuming the pump and plumbing up to the PH is functional) even though there may be a blockage someplace in the block?
All in all….I would think that the best placement for the tell-tale source would be AFTER the water has passed through the block and has done it’s job….but I’m not at all sure that all engines are set up this way.
Case in point: I just finished working on a Mariner (Yamaha) 8HP that spit tell-tale water like a fire-truck….but the engine was running hot. Salt corrosion in the passages was the cause. Someone relying on the tell-tale on that motor would be in trouble 🙁
