Hi Rich,

Guess I have a dirty little secret to confess. I don’t really have a 424 but the orphan cousin, the 422. Hull, rig, engine and most systems in common but in addition to the center cockpit, there are some significant differences.

I guess one is the ignition switch and instrument panel. I thought the 424s were like mine but maybe not. I have a panel in the cockpit with all the instruments and the switch in the panel. Fuel shutoff is a solenoid activated when the ignition is on so no cable. Would prefer a cable since it’s less likely to fail and easier to fix than a solenoid but oh well.

So the mods would be doable but I already have a very, very long list I’m trying to finish so I can get back in the water this spring so really prefer a quick and easy swap out the switch fix on this one.

I think I’ve found a couple of Cole Hersee switches that will work, even though they aren’t specifically made for diesels but do have a momentary position. My glow plugs do run off a solenoid on the forward end (back of the block of course) of the engine, just not certain how many amps the solenoid draws.

Thanks
Skip

PS. Please don’t kick me off the forum just because my model is two numbers less than the norm.

What engine do you have again? Usually there is a button for the glow
plugs. If you have a Westerbeke then just wire the switch exactly as it is.
The glow plug button is wired into the starting circuit.

You can tell if you have to press the glow plug button and a start button
to start the engine. Then the power for the glow plugs come from the
starter relay power.

I have the original W58 and still have the original ignition switch. The switch does work but the key is very, very loose and you have to jiggle it just so to get it to turn. Could fail at any time and I’m certain that when it does fail it will happen at the most embarrassing moment.

The original switch is OFF/ON/START with a push momentary for the glow plugs. I could wire the new switch that has OFF/ON/START without the push so the glow plugs are connected to the start circuit but in that case they only work when the starter is cranking. In my limited experience the recommended way to use glow plugs it to heat them for 15-20 seconds before cranking so think the push to heat function is the way to go.

So, preferred solution is to replace the original switch with a new with the same function.

Hi Skip,

There is a direct replacement for your switch. Instead of an idiot light,
consider a 12vdc piezo alarm from Radio Shack. I replaced my failed buzzer
with it and when there’s high temperature or low oil it makes enough noise
to wake the dead.

Bob

Wake the dead (or asleep or inattentive) is what I want. That piezo alarm sounds like it’s just the ticket. Thanks

Hi Bob,

I have a new ON/OFF/START switch but the only way to use that switch with the glow plugs is to connect their circuit to the ON position which would mean they are always on when the engine is running. This is my first engine with glow plugs but I think that is a no no and would burn them out quickly?

I don’t have a relay behind the panel for the glow plugs. The wire goes from the ignition switch straight to the relay on the block. That relay is pretty large and I have no idea how many amps it will draw but based on the size it could be a few.

So far all the switches I have found with a push/momentary feature are made for a carb choke which draws very little. Think one of these would handle the power to engage the glow plug solenoid? Or, do you know the rating for that solenoid?

Thanks
Skip

Skip,

West Marine and Defender’s both sell OFF-ON-START switches – all you need
for the Westerbeke is the off and on position. The glow plugs don’t take
that much power and the switch is perfectly capable of passing it. Mine
might even have a relay for the glow plugs just behind the instrument
panel, but I’m not sure. They’re cheap (<$15) and easy to install. You
can get them at any auto parts store.

Skip,
Why not just put the glowplug circuit on separate momentary switch. That’s
how my Westerbecke was wired. My Yanmar switch turns counter clockwise to
engage the glow plugs, but I’ve never used that feature.

Thanks John,

Had thought about using a separate momentary for the glow plugs but available spots on the instrument panel are pretty limited and small. Plus my instrument panel has a gasketed plexi cover to keep the water out and just a small cutout to reach the key which would make access to a button in the panel problematic.

Also, I was thinking about using that space to add an idiot light to the oil pressure and temp sensors. Yes the gauges work but want something really bright guaranteed to get the attention of whoever is on watch if something happens with the engine.

So yes a separate button would work but not the most ideal solution and I’m striving for perfection. OK, stop laughing. I’ll confess that I will settle for workable and easy.

Hi Adam,

Have lost touch with the guy in AL that was going to pick it up. Been emailing with no reply. Was hoping he had come by but looks like he dropped the ball.

Very sorry for all the trouble. I feel embarrassed about the whole thing and feel like I have strung you along. Well, you know what they say, no good deed goes unpunished.

At this point not sure what to do next. Will see if I can come up with a plan C.

On top of everything else I guess this also means I won’t get the New Found Metals port he had for me.

What is the approximate size of the 424 rudder?

Adam

Will be at my boat tomorrow and measure it.

[skipmac]

I found an article about building cassette rudders which gave some guidelines for calculating the size you need based on your existing rudder, position on the boat, etc.

My plans are for in the water surface area of the cassette rudder of 50-65% of the existing rudder and 1″ diameter pintles. I am also thinking of adding s small balanced area towards the bottom of the emergency rudder to make it easier to steer with a tiller.

[skipmac]

I talked to Scanmar a couple of months ago while on the hunt for a large gudgeon and pintle set to build my own. They were very helpful, good guys but their emergency rudder setup was several boat units.

[skipmac]

Have been researching the emergency rudder issue. If you haven’t already found this, the only way to go is a cassette rudder which is a structure that has a frame for the rudder to slide down into instead of trying to drop a rudder with pintles attached into gudgeons on the transom.

The reason for the cassette design is that boaters that tried to install a rudder with the pinties attached found it impossible to line up the pins with the gudgeons on a boat rolling around at sea and flopping the rudder side to side.

Google cassette rudder and you’re get lots of pictures and plans.

[skipmac]

I believe the prop shaft follows SAE J755 standard. The approximate measurements on my shaft.

Shaft Diameter – 1.5″
length of taper – 4″
Diameter at the small end of the taper 1.25″
Length of threaded section 2″
OD threaded section 1.125″
Threads/inch 7 or 8

Should be able to find an online SAE standard.

Hi Adam,

If you are still out there, have someone leaving AL for FL on the 12th that can pick up the stove.

Thanks
Skip

[skipmac]

Thanks Tor. To be honest I wouldn’t swear where I saw the photo but do remember seeing it somewhere. Thanks for posting. Will honor your request but darn I was planning to sell the plans on eBay. There goes my latest get rich quick scheme.

And I’ll answer to most anything, Skip, Skipper, Skippy, Slip, Zip, Hey you.

[skipmac]

Hi Tor,

I recall seeing a photo of your seachest on your website but last time I looked the photo eluded me.

Is it still there? Can you post a link or directions to find it. Want to do a similar setup and don’t see any point in reinventing that particular wheel.

Thanks
Skip

[skipmac]

Hi Adam,

Hope you had a Merry and a Happy. Still looking for a home for the stove? I have a volunteer to transport it from AL to FL in a couple of weeks.

Thanks
Skip
