Welcome to the forum!

Thanks for starting this forum! I’m having an intermittent problem and hope someone can explain it.

I have a 1974 20' Duffy.  I'm looking for a electrical schematic.  If any exists please let me know, or email me at maddockssd@hotmail.com

I'm also looking for a replacement for the throttle control which is a 2 speed forward & reverse.  The factory wants $2,400 for a new system, but I believe there are less costly options available.  It might only be a reostat that I need...if any one has knowledge that will help, please pass it along.

Thanks,Patrick

Hi Patrick,  try calling Duffy for the diagram.  They were able to give me some info about my 2002, though not a wiring diagram. 

I changed my controller to an Alltrax xct.   It is a more modern design than the original,  and generates much less heat.   You may also need to change the throttle to a 2 axis joystick.  Ebay's a good place to look. 

Hi! We just bought a fun 18" 1991 Duffy Launch for cruising the Hillsborough River in Tampa, FL. We did have a mishap with the tow eye coming loose. We can't find any way to access from inside hull to repair it, without cutting a hole behind the bar mirror. Anybody out there know better? 

I'm a recent new owner of a 1993 Duffy 18 in northern Indiana. It's in great shape but needs a few updates. Just looking for suggestions on DIY improvements. 

Welcome lnglinssey,  I  looked in my bow,  and I couldn't see the back of the tow eye,  which is odd,  because I just had it replaced.   I'll ask my mechanic next time I see him. 

Hi Mike,  if you haven't already got one,  a remote battery watering system is a cool thing.   I learned about them on this forum,  and bought a used set on ebay for about $80, I think. 

I also really like my model ha-02 (various brand names on ebay) battery balancers.   They keep the batteries balanced to under a tenth on a volt. 

We cut a hole behind the mirror. I verified with Duffy that this is the only way. Fortunately, the mirror hides the hole just fine. 

Would like to find out where I can download a owners manual for a 2004  21’ classic 

Also need to replace refrigerator, need to know best place to shop 

Thanks Bill. Set to receive my first Duffy (18' Snug Harbor) when it comes off the assemply line for a Halloween delivery. Being here in SoCal we can enjoy year-round use of the boat.  Though its not my first boat, it is my first electric boat and so I look forward to engaging with fellow owners who doubtlessly have much greater knowledge and experience.  When you get to a certain age (and I'm there), you learn that relying on the collective wisdom of the crowd is infinitely better (and more economical) than trial and error education.

So, thank you and others in this forum in advance for your patience, expertise, humor and maritime insights. 

Welcome!  I think you'll love the boat.  Our experience has been that where you use the boat is critical to how much you enjoy it.  The previous owners of our boat hated it.  They were using it in fairly open waters which often got windy and unsettled.  We use it on a secluded "creek" (which you would probably call a river) just off the Chesapeake, and it's magical.

Our experience has been that hard documentation on care and maintenance is hard to find, if it exists at all, so the input of those with knowledge and experience with these boats is especially important.

Enjoy the forum!

Bill

I have a 1997 16' Classic with the old style suspended canvass Dock Cover with the Sandbags on the side.

I love it and have kept it alive for all these years with lots of thread, patches, Velcro and snaps.  I need a replacement but the Newport Headquarters can't help me - no even a referral to a canvas guy.  There are a number of Marine Service outfits here in Missouri who will keep "Sparky" for a few weeks and make a new one.  $$$$.

Is there a source for NOS replacement canvas? Is Sunbrella still the canvas of choice? Any have a similar experience with this?

Thanks!

Recently purchased an ‘07 Duffy CAT 16 to slowly cruise Lake San Marcos. It’s a no wake Lake and I don’t think there’s any concern about making a wake in this tub! Haha

Bought used with a new fully enclosed surrey and new batteries 48v. However, I’m a recovering A-Type so trying to fix a few things.

Most importantly is the Hour Meter. Shows 19.9 all the time.  This has the digital, but I hear the replacement is analog. 
Any help locating this part would be greatly appreciated. Preferably digital so I can plug and play. 

Hi, Hoping someone has some helpful information... I have a 2001 Duffy Cat 16 my boat stopped working, even the stereo. When I plug the charging cord in, a loud beeping sound occurs on and off from what appears to be the charging panel under the seat on the side of the boat.  I called Duffy to trouble shoot and they asked me what the color was of the blinking light on the steering console. I told them red, and they said it is definitely a bad battery. I checked all the batteries and yes 3 of them appeared to be too low and not charging (Dead). I just replaced all 8 batteries with brand new Trojan T-105. Problem is, the same issue occurs. No power, even to the stereo when I turn the key on. Plug in the charger and the same beeping sound and flashing of the red light on the console.  We know it isn't a battery.  I am looking for a fuse box, but can't find one in sight anywhere. Anybody know where I could find them to check? Or does anyone know how to fix my current issue. With full brand new batteries, you would think the boat should run and at least the stereo and lights turn on without being plugged in.  Any help is appreciated.
