Per Yanmar Technical Bulletin YMTQTB11-017 paragraph 2.2 b. you may leave the SD-20 sail drive in reverse when you have a folding prop.

The greatest source of water I found was the aft side mast groove that extends through the deck, Pull the mast boot and get some sealant that flows with a thin tip inserted in the groove and fill that groove well into the hole where the mast goes through the deck. Extend bead so it is filled above ...

Ros,

The Technical Committee has contacted Edson and asked them to provide a quote for a replacement wheel with all the required pieces so it is bolt on compatible. This should include any parts required for proper operation of the center screw brake adjuster. Once the proposal is received with the ...

The Ronstan Winches have a different diameter base, are lighter and have different gear / power ratios than the original Harken winches. Thus they are not acceptable for one design use. The only acceptable one design alternatives are the Harken winches previously approved by the class measurer in ...

No - it was powder coated

Dan,

Remove all the leather and foam. You get new foam and leather with the kit. I sanded the chipping spots and sprayed an etching primer. Once that cured I used a spray can of white epoxy appliance paint.

Some pictures below when I did this task previously. The trick is to keep the leather wet ...

I did some more online searching and came up with a stainless steel approach. The following should screw into the saildrive with BSP threads and provide direct transition to an NPT thread. A 90 degree male NPT to female NPT elbow provides a transition to a stainless ball valve with male/female NPT ...

Just another thought.. What if the original valve was used as is and an inline ball valve put in the exit hose. It isn't as failsafe as a full mechanical connection and wouldn't meet ABYC standards, but still provides an easier isolation for the water from the saildrive.

Jerry,

I replaced mine in 2016 and I think the headliner was dropped to access the hardware.

Todd - even though the Volvo valve is plated brass, I think a DZR Bronze valve would be better suited for seawater. Something like the Groco IBV-500.

Todd,

I've been thinking about doing the same thing for a few years so your post prompted me to do some research. I would suggest either a dezincified marine bronze (DZR) or Marelon setup for replacement. If you are able to remove the existing Yanmar valve and could check the saildrive threads (e.g ...

That was a mod somebody made. Just remove it.

Mochi Fanta - I know the previous owner raced one design extensively. I have not seen the boat since he sold it. Do you do one design racing?

Yes - that is the correct datum point.

Todd,

The fuse on Vento Solare is mounted inside the engine compartment mounted on the port bulkhead just behind the removable stairs. It is just above the voltage regulator which is also bulkhead mounted. See picture below with the large diameter red leads.
