Re: Custom Engine Panel Design

All good ideas above. Consider separating the indicators from the switches. The indicators and light should be where you can see them and sealed from sun and water. The switches can be elsewhere out of harm's way. Key is indeed useless and a maintenance problem.

Re: Custom Engine Panel Design

Well, 2.5 years later and I finally started this project!

First, my original plans were overly ambitious. While it would be nice to have Nav/Spreader lights etc in the cockpit it's not really needed. And the extra wiring would just be a pain.

Still, the old panel was an eye sore (see it below) and in a spot where it was exposed to being kicked or bumped. Here's what I settled on:


SSI Plastic Recessed Panel:
Recessed Panel | SSI Custom Plastics

Sunlight Visible and Waterproof LED Indicator Lights:
McMaster 2779K13

New rubber boot for toggle switch:
McMaster 70205K26

Heat Shrink Fully Insulated Quick Connects:
McMaster 72625K76

Write-On Wire Labels (I'm a big fan of these):
McMaster 8668T11

The picture shows some of the steps. After doing some planning with MS Visio I first cut a template for the panel itself. Using the old panel as a guide with the router table I cut out the big holes for the guage and buzzer and drilled out the other holes. I was able to test fit this (realizing that behind the panel the toggle switch hit the buzzer), and then copy the plywood template to the panel with the router table again.

I also made a plywood template for the cutout that has to be enlarged on the boat. A cordless Ryobi router will be used for that.



Comments:
-I'm probably giving up visibility on the indicator lights which are fairly small. Though the buzzer should still be the primary alarm.
-I don't have labels for the lights though I chose red for oi/temp and orange for charge. A buzzer plus a red light is going to mean shut-down! And I'll remember the order.
-I have some sunbrella fabric that I plan on using to make a roll-up cover.
-The unpopulated indicator is going to be green just to show that panel power is enabled. This is the one design addition to the panel.
-I bent 3/16" lexan to make a back cover to protect the wiring. Though I have yet to decide how to fasten it.
-I grouped the controls in the lower right because I may cover the panel with lexan and have a cutout in that corner to access them. This would mostly be for kick protection.
-In my diagram the key and the start button were aligned on the bottom but in real life the fact that their centers are off looks like a mistake. I'll probably address that.
-If I added an oil gauge I might put it where the buzzer is now, and then move the buzzer behind the panel (MainSail's suggestion earlier).
-After being frustrated by the lack of availability of good marine connectors I've definitely settled on fully insulated quick connects as the best easy solution.

Yep, that's neat and nicely compact.

Yanmar haven't learned the art of compact yet, their panels are large and mostly unpopulated. What I do miss on your panel though, are the big warning lights that come on with oil pressure drop or overheat on the Yanmar panel.

I guess if you have a buzzer that's all it really needs - I have just got used to the lights as well.

But that is a nice panel.

Re: Custom Engine Panel Design

Regarding tachometer senders and tachometers:

Don't know about the 1GM10 but for my 2QM15 the tachometer sender is a flywheel sensor and is located on the engine block just forward of the transmission on the port side. It has two male terminals on it.

For speed sensing using this type of sensor the tachometer used must be matched to the number of teeth on the flywheel. My engine has 114 teeth on the flywheel. For OPer: 1GM10 has 97 teeth.

My memory is that the stock number of the meters have the no. of teeth they are designed to work with as part of the number. Also the meter face has the number of flywheel teeth it is designed to work with engraved on the meter face.

For my Yanmar (and others) the alternator output can used for tachometer sensing IF it has an alternator fitted with an "R" or "N" terminal. VDO meters can be used in this application. To match the VDO tach with the alternator you have to know the number of electromagnetic poles of the alternator and buy a tach designed to be used with that number of poles (frequency matching the pulsing waveform coming out of the alternator).

On Yachting and Boating World Forums (www dot ybw dot com) one member mentions converting an alternator for use with a tach for a 1GM10 and might be worth a look for those interested. The thread is "Recalibrating Yanmar P116 Tachometer to P97 - Possible?"

Works well for me, not too fancy, but compact and with the basics. You can purchase it separately (don't know the price). There is a buzzer (oil pressure alarm) but it is behind the panel somewhere.

Some of them trigger off the rear of the alternator - you may be wise to check that out before spending your sheckels
Yes, absolutely. At the moment, I know nothing about the yanmar tach signal and for now, I was generally assuming that this gauge would work with it. But I definitely need to check.

Actually I thought there was a signal coming off the alternator until I was at my boat Sunday and saw an extra wired device at the rear of the motor and realized it was a tach sender. Your mention of a flywheel sensor confirms that because that's where it was.

If you know any more specifics please share otherwise I'll be posting the info whenever I get around to confirming it.

Note that VDO makes a whole range of tachs with various RPM limits. They do make one with a 4k limit which is what I'd want for the yanmar.
