I tend to go for the basics:
Tacho
Fuel
voltmeter
Trim
Water pressure ( gives early warning than temp. gauge or alarm)

By the way Aiden, the Triumph Cub was a 200 not 350: the 350 was the Twenty One.
Cheers. T.

But a water pressure gauge will only give you an early warning if you're looking at it all the time, as will a temp.

Unless you're saying that if you have issues with the impellor then an early warning sign might read in a low water pressure at startup.

Hi Hightower

Yes, I agree with you. You certainly need a high temp alarm, however you may not hear it at WOT and I think that pressure gauge is more useful, particularly when running engine on muffs and because the tell tale will not start until the thermostats open. ( on a Merc. anyway)

This topic started on an Evinrude engine and an Evinrude will give an alarm signal at overheating.
In my case the water pressure gauge is in front of me so I have a glance at it all the time.

I must admit that a water pressure gauge is probably going to get fitted anyway, I was playing around with console layout and can get the Trim/Tilt, Fuel, Volts, Water pressure and another gauge on there.

What else might be needed? I was thinking a clock?

When looking for guages on an etec you might consider the nmea 2000 devices. It looks like Evinrude will change over to this system with lcd digital displays as soon as october this year

We use water pressure gauges on the race boat because we have a lifter - they are also on the Merc Smartcraft gauges - they will not tell you if the engine is overheating, but they will tell you that water pressure has dropped before the engine overheats, in other words if you have a partial blockage, a sick impeller etc the this will show up - worth fitting then!

I have a water pressure guage fitted and find it very reassuring. Does it measure the pressure of water going into the engine or what is actually circulating around the block?

So this water pressure gauge, does it have a transducer or a tube running from engine to gauge?

Tube running from engine to gauge. On a Mercury anyway.
