should my warning buzzers/lights come on when I turn on the ignition,my boat is 2001 17' Hurricane

also my yamaha 90 2001 does not seem to have any grease nipples on the main shaft where the engine pivots from side to side,one last thing I would like to fit a temp gauge,but my local Yamaha dealer says it may interfere with existing warning buzzers ( which I have never heard) and was part of my opening question. thank you Tedley.

I get no warning buzzer when starting my Yamaha F150, but this may not be the case for other engines.  If you want to check the buzzer, then try starting the engine without the lanyard attached.  The buzzer should sound.  

The buzzer will sound in an over temperature situation, low oil pressure, or if there is water in the fuel/water separator on most Yamaha engines.  

Most Yamaha engines have a port that allows for the addition of a temperature sensor or water pressure gauge.  I would say that most guys looking to add a gauge op for the water pressure gauge over a temperature gauge.  If you look at a rigging guide for your engine it will show where to install the temperature sender on the engine.  Its pretty simple to do, and it should not interfere with the existing warning system. 

Here is a photo of the location for the temperature sensor or water pressure gauge on a Yamaha F90 engine:

I think what you hear when the ignition is turned on is your warning buzzer. It should be audible until the engine starts. Most likely your boat has a electronic control module that takes inputs from the engine and will sound an alarm if an input is out of a preset range. If you don't hear the alarm when you turn the ignition on means it maybe disconnected. You may be able to add a temp gauge but I think it would have to be completely separate from the engine control module. I'm not an expert, just info I have learned from the years of boat ownership.

thanks for the reply Dave,I hear no buzzer or see any lights,so have to assume it is disconnected,which is not good as I have no warning if oil pump stops or engine overheats

I have the same issue on 06 Yamaha F150, can someone in the know post pic of the connection in question.

thanks Ernest T,I will go with either pressure or temp thanks for the info and photo

If you install either gauge (temperature or water pressure) using the port on the engine, this is completely separate from the system that controls the warning buzzer, so you would not have to worry about any interference, but this would not provide any warning sounds in an overheat situation.  These gauges would provide a visual reference to the condition of the cooling of the engine, but no warning if something was out of spec.
