Speedometer hose shooting water

Hi new to e-nation. Repowered my 1976 Grady Hatteras 204 center console w the E-tec 115. Couldnt ask for a better running engine. Odd thing happened last time out i noticed water coming out of the Mesh that contains the binacle and battery wires and all of that. I had no idea there was a speedo hose in there until i cut open mesh to see where the hell water was coming from. I called Mariner that did my repower and one person said a hose must of popped off engine, and another guy got on phone and said plug the hose on lower unit as i do not have a speedometer. Has anyone had this or know of this issue? thx any info be helpfull! Dennis Plymouth Ma.

Re: Speedometer hose shooting water

Analog speedo gauges use water pressure from the motor to the gauge on the dash.  When analog gauges are removed, the hose is detached.  In your case, it was re-attached to your new motor and why water was spraying under your dash.  Disconnect the hose on the motor and plug or cap it.  Done.

Trace the hose back to the motor to see where it is attached. It is possible that it could also be for a water pressure gauge that was not hooked up on your boat or the hose never plugged during rigging.


If it is a speedometer hose, it will attach to front upper part of the lower unit and you can obtain a rubber cap and tie-rap for the fitting.

If it goes to the engine block, it was for a pressure gauge and is best to remove the fitting and install a brass plug in its place.
