My ignition buzzer is slowly dying. I bought my Hunter 38 new in 2009 with the 40hp Yanmar and all associated factory equipment. I noticed a few months ago that the well known loud buzzing sound was missing when I turn on the key. Putting my ear down by the control panel, I could hear a very weak intermittent buzzing, but I am certain nothing would be heard over the engine if I suffered a loss of oil pressure while running. A mechanic told me the Yanmar replacement buzzer is $700 and likely to fail soon. That is far too much for a simple buzzer device. He recommended an entirely new panel, but why if the only problem is the buzzer?

I pulled the panel. The buzzer is a knob like device about the size of a piece of hard candy located right next to the back of the tach. I tapped it a few times with my finger, while the key was on, and it started buzzing like new. A few weeks later, it is back in failure mode. My question: Can a non-electrical engineer guy like me easily replace the buzzer with something more reliable and less expensive? If so, with what and how?

Someone else posted a photo of their panel. Thank you. Mine looks the same.

Yanmar uses two kinds of buzzers. A two pole buzzer which is rather inexpensive and a five connector unit which services all sensors and sells for around $120. Give Phil a call and see what he has to offer. I know some that have opted to replace the buzzer with two pole units mostly used by jet skis. That means just monitoring oil pressure and relying on the lamps for temperature and alternator charge.

$120 is good insurance for not having an engine failure later. Replace it with the correct buzzer. If you have 5 terminals, stick with five.

www.torreson.com Long time Yanmar dealer.

If you have a part number, you can google that number and maybe save ten bucks.

Gregory - I am not sure what is the device that you have on your panel - but on my C36 it is a soanlert that is easily available at Radio Shack. It has 2 inputs and one common pin. It has a steady sound - indicating high water temp and an pulsing tone with 1 sec on 1sec off input indicating low oil pressure. It has about 110dB 3000 HZ frequency output.

Here are some links
See the PDF file for specs
Looks like you can order one at about $ 12.00 excluding freight.
The part No is SC616Ju-1

Sorry, I had not checked the price in a while, the current price for the Buzzer from Yanmar is $185.00.

I think one very valuable lesson here is what a thief this mechanic is. He apparantly wants to convince you that the buzzer is incredibly expensive so that he can sell you an entirely new control panel. I hope this isn't your go to guy for repairs.

I replaced ours with a sonalert with diode isolation to warn of oil pressure or overheat. It was junk from my junk drawer so no cost, but they are cheap and will outlast a buzzer any day.

At $185 dollars it would be tempting to head to radio shack. One problem is insurance. If you end up with a fire in the engine with a cobbled in piece of safety equipment they are not going to cover the loss. See if Phil has the exact match at a lower price.

Re insurance ... if a competent marine mechanic recommends and installs an appropriate device, eg a $20 buzzer or Sonalert, and charges an hour to do so ($110), that should satisfy the insurance company, right? And you still save.

I would think so
