Johnson GT150 VRO tell-tale

[Mile-High Mariner]

The tell-tale stream on my 1989 Johnson GT150 has suddenly stopped putting out a strong stream of water. It drips, instead, although the other cooling water outlet ports seem to be working adequately. Is the tell-tale water stream critical to engine cooling, and how do I best restore the flow? Thanks for your input!

Welcome to the forum!<br /><br />The telltale is critical in the sence that you do need a visual check so that you know the water pump is working properly.<br /><br />But is not critical to engine cooling, Because water directed to telltale does not circulate through block.<br /><br />I would suspect that you have some sorta trash blocking the flow out of telltale.<br /><br />Pull the rubber hose from telltale and start engine while on the muffs. If water flow is then good the your little plastic nozzel is pluged.<br /><br />If flow from hose is not good then hose is pluged some place. you will have to remove it and unplug.<br /><br />I would let motor idel a good 20 to 30 minutes on muffs to see if water is flowing thru block T..stats without overheating.<br /><br />Good luck!
