Gone- given away to a nice fellow 34 owner here in San Diego.

Had my backstay converted to MkII type, so have the original backstay and need to get it out of the garage. In good condition.

1/4 inch pipe thread in brass
Paul
PS:  took it into the hardware store and had it sized.

Thanks, Paul, on the way to Home Depot.

Thanks, all. Where exactly do I find the parts listing?

Does anyone know offhand what the thread size is on the shutoff plug for the oil siphon hose on the bottom of the pan on a M25XP? It looks to be about 1/2 inch. Thanks.

Here's the one from CD I was referring to: https://www.catalinadirect.com/shop-by-boat/catalina-38/electrical/breakers-switches/engine-panel-push-to-start-or-glow-plug-button/

Thanks KW, for $16 I'll buy a new one from Defender. Interestingly, CD offers only one switch and says it's for start or ignition. Also, how do I find out if I have a pre-heat solenoid, just in case it ever goes bad?

Update- Defender has a $25 minimum and wants $20 for shipping Found the switch on Amazon for $18, no shipping

KW- I did some checking and here's what I found. The replacement switch that Catalina Direct sells is rated at 10 amps. I then looked up the ignition switch that I previously bought and it is rated at 15 amps, so it would seem that the three-way is actually more robust than the original switch. Or am I missing something?

Not sure, but all I am doing is taking the original wire from the glow plug button that goes to the engine and splicing it to the new ignition switch.

Hi guys- yes it was the glow plug switch. I do have the three-way ignition switch so I will send the wire to the third pole on the switch. Question is, does anyone know what the gauge wire is? It looks like 12 to me, but it may be 14.

Ron- thanks for reminding me- I had bought a new switch after the old one died, and I think it is a three-position. If it's the old switch, problem solved!

Thanks for the replies. Yes, it is an M25XP, typo on my part. I just realized that I was testing the glow plug button the wrong way  Thanks for the advice on the shutdown cable, I'll check that out.

So the MX25 wont fire up after much cranking. I checked the fuel filter and the fuel pump and both appear to be working. I thought I'd check the glow plug switch for power, and I am getting twelve volts across the two back ends even when the button is not pushed in. Is this right? It would seem that I should only get voltage across the terminals when the button is pushed in. Am I missing something?

Updated.

Thanks, that's what I thought. The wiring is obviously not the original, as the wire going to the fuel pump is blue, and the wire going to the gauge is black. This is in line with the wind gauge which reads 180 degrees off and was obviously put on backwards.
