Tell tale on an inboard?

[alt]

I have a Mercruiser 1.7 diesel inboard with an Alpha one Leg

My main concern is that I am always paranoid that the raw water system may not be pumping (Although I know it is, as the engine never overheats). It's just paranoia I know, but when I had an outboard I had the re-assurance of being able to see a tell tale p1ssing out the back

Is there a mod available to install a tell tale on an inboard engine?

Not as far as I know. However, you can normally fit a heat sensor with alarm onto the exhaust pipe which gets suddenly very hot if the raw water is not being expelled into the exhaust elbow. (Assuming a sterndrive works the same as a shaft drive engine with raw water injection into the exhaust).

We ve got one on our Mercruiser with a leg..

I m can't remember where the take off is thou - will look next time I m on the boat.

Is there not one already fitted, usually a flow alarm as opposed to a tell tale.

I have a temp gauge for the enclosed water system

Do you not have a "Low Water Flow" type warning light on the panel?

Nope, the closest thing I have is "Water in fuel" ... nothing else to do with water

Is the water pressure from the impeller high enough for you fit a water pressure gauge to the raw water side of the cooling system?

Right, finally had a look at ours - fitted to a Delta.

There is a take off from the front of the thermostat housing which has a pipe running to a skin fitting on the transom, The pipe diameter is about 5 mm.

I m not sure if this is an add on or a Delta modification or company spec.

Thanks for that, i'll look into it. I don't want to just throw a pipe on in fear of taking away too much water pressure from the raw cooling system
