Another (but different) ? on water telltale?

[redcardref]

1988 Bayliner, 125HP outboard. Normally for my motor, at idle, I have a "robust" spray of warm h2o from exhaust holes at rear of leg. Although it's a bit tough to see while driving, I can see while skiing a steady "pour" coming from those two holes (obviously going at fair speed, i have no tach). Yesterday, while on the river, I had the opportunity to have someone else at the helm and I sat in back, and I noticed at WOT, "NO" h20 coming from the exhaust holes!!! I have not been apparently overheating, no alarms sound. I had the the helmsman drop to idle, and the spray was just like normal. Could I have normal operation at idle, and a problem at higher RPM?? What would be that issue? BTW, river has had some low spots, some trouble with sand bars and agitated sand as a result. Thanks for any ideas! Strike3

It's probably a good idea to check your impeller. But, at high speed, most of your exhaust gas and water is going out through the motor leg under the surface of the river.

Strike3, <br /><br />I'm no expert, but I have read the spray will diminish as the RPM's increase. As long as you have a good spray at idle, you should be OK.<br /><br />Replace the impeller and check the thermostat often!<br /><br />Chris
