Troubleshooting the seal drive alarm, found that that the supply voltage measured at the sensor is about 5v.

The output voltage on the white/yellow wire input into the alarm reads
0.64 vdc when the sensor is not submerged
0.71 vdc when the sensor is submerged

Unsurprisingly no light or buzz.

This worked well for Strider.

Additional hardware needed for the line that runs through the top

Has anyone replaced their engine mounts? Yanmar wrote "4 years or 1,000 hours". I am quite a way past that number.

What is hard about this project? Does the sail drive need to be supported from underneath?

Anyone have good sourse to purchase a new engine pane cover, either ready to go, or by my own design?

My key location moved a bit, need to relocate the cutout. also broke that piece that covers that cutout.

I use extra thin black electrical tape, distance between them almost does not matter, just cover about six inches from the stay in towards the mast. It meets the need to be able to communicate to crew and replicate settings.

I am at the point of purchasing the 48-YSP-3YM-B kit for my 3YM30 and 110 Amp Alternator.

1) Is it any easier to get the right tension, or during this conversion does it make sense to also purchase the balmar belt buddy?

2) Which version of the belt buddy is for the 109?

Before doing work on the traveler track, think about the mainsheet cleat support post underneath. It is better to combine the two projects if you are thinking to replace it, or at least purchase the stainless steel post to have handy even if you don't plan to as you may find corrosion or the screw ...

Additional Cons:
Labor costs: Replacing the Harken also involves shortening the rod on the bottom and getting it correct within say 1/2 inch. Too short, and you will always have pressure on your backstay; too long, and you will lose the ability to achieve full tension.

While I could have calculated ...

I have had thoughts about installing some kind of grab bar over the companionway instruments, making it easier to traverse and reducing the frequency people touch the displays.

I would recommend following Bill's advice to change the seals.

In favor of the Harken unit:
* Has a gauge, but its too hard to read in a bouncing sailboat. I still use a stick with lines as I did before, and never reference the gauge.

Against:
* I don't know why, but more prone to knuckle ...

There is an option for a magnetic pickup on the flywheel housing on figure 6 of the 3YM30 parts manual. I will look there when next on Strider.

My boat may be different as neither the stator (in) or the tach (out) pins on my Balmar MC-614 are wired to anything.

It's as if there is some sensor not connected to the alternator.

The wire to the DC panel tach is the orange wire from the 8-wire cable.

I am confused how the engine panel tach get's its input. The available lead from the alternator is connected to nothing, the contact on the Balmar smart regulator is unused.

Strider, #332 has Yanmar 3YM30 and 110A Balmar Alternator

p.s. I suppose it is possible I disconnected the lead from the ...

I took a look at my J/109 yesterday to think of an answer I could bring back. Don't have much to offer other than the savings is minimal. Removing the winches gains very little. The tops of the spinlock clutches vs the top of the winch is maybe 4", take out the clutches gains another 3/4" maybe ...

For the 3YM30, some things I learned to share:
There were not many skills needed. Completing a general marine diesel class is a reasonable prerequisite so you know your engine before getting started. Lots of caution is needed. Although the acid did much of the work, it took me 16 hours to complete ...
