Re: Clogged h20 pump line 2005 4 stroke honda bf115 a5xa
I am not a mechanic, but it is my belief that the small restricting orifice at the end of the tell tale line is unnecessary. The only thing that it accomplishes, IMHO, is catching sand particles, setting up a "log jam" in the tell tale hose. Once the orifice is clogged it is just a short time later and the entire tell tale hose is packed solid with sand.
I have removed the tell tale restricting orifice off of my motor and replaced the tell tale hose with a longer, thicker hose (with the same inside diameter). At the original position of the tell tale orifice I cut a circumferential groove in the new, thicker hose so that I could secure it in the cowling opening. To give me a way to pull the thicker hose through the cowling opening I cut the end of the hose at an angle so that I could grab the end with a needle nose pliers and pull the hose through to the circumferential groove.
It works great. My tell tale never clogs, even after grinding mud and sand with my outboard jet.
My engine runs cool. I did a full season with my jet unit in silty, sandy rivers and never overheated the engine. At the end of the season I rebuilt the water pump using a factory water pump kit. It was good insurance which I accomplished when I had the jet off for annual maintenance.
