Boat ID?
I have had this boat since I was a kid. I picked it up with starter glow plug igniter and a stand at a garage sale for $100. It came with a K&B 7.5 inboard with venturi and exhaust throttle but I could never get it tuned with that thing. I am just now trying to get back into it and have recently bought a K&B red carb and plan to wire the exhaust throttle open. I have already redone the servo linkage to the new carb.
I am kinda curious if anyone knows what kit my boat is, its all wood from what I can tell. I have added 3 pictures of my boat to my gallery. |
I have more pictures from different angles if that would help.

Looks like a Dumas boat, don't remember the name off the top of my head though
|
Well thats at least something to go off of. Once I can post pictures I will try and get some better shots in this thread.

After doing a bunch of research it looks like it might be a Dumas DV-40 but its all wood not fiberglass.
|
They (all Dumas boats) where all wood prior to fiberglass offerings.
|
Agreed, Dumas sold mostly wood. Toward the end of their run as the "go to" place to buy boat kits, they offered wood, fiberglass and vacuformed plastic hull and parts. Just looked at their website and it's a hodgepodge of old boat kits and Guillows style airplanes

DAMN!!!!!!!!!!!!!!!!! That's the same radio I started out with back in 1982. There are, however, two issues with using it now:
1) Channel 42 is on the 72MHz band and that is, and always has been reserved for aircraft only 2) That radio is tuned to wide band, meaning the channel, 72.630MHz, has a signal pattern that runs 40KHz above and below the center. Starting in 1991, all R/C radios were required by the FCC to be narrowed down to 20KHz. This means that your radio would be illegal to run in anything that doesn't fly and is technically illegal to turn on |

After doing a quick scan of the radio offerings available I realized there are a lot of them to choose from. Anything in particular I should be looking for in a radio set? I mean other than not being for air planes.

Now that is a good question. There are a few things you need to think about to figure this one out:
1) Cost. How much do/can you spend? This comes down to your finances and what you are willing/comfortable to spend 2) Memory space. How many boats do plan to run using the transmitter? 3) Functions. How many functions do you need? Are you looking at having more complicated boats later that require more than rudder and throttle? Now, to put these in perspective, I need to elaborate. Cost comes down to operating system, brand and functions. Operating systems, such as Futaba's FASST and FHSS, affect the cost of the system. While the systems do the same thing, the way they work isn't totally the same. Memory space is basically how many models your radio can handle. Since each model will require different settings, the more memory spaces mean you can operate that many models Functions are kind of a given. This comes down to the number of channels and what you want each one to do. In my case, I run my boats with a Futaba 4PLS. It has 32 memory locations, telemetry capability, four channels(throttle, rudder, one with a variable output and one that's switched) with several electronic settings and mixes. You may not want that many bells and whistles. A three channel radio may be what you would prefer. The Futaba 3PRKA is a basic pistol grip type radio with a few bells and whistles but not the complexity of my four channel. There are other brands, besides Futaba, but it is the brand I know best which is why I referred to it |
Thank you for that information. I am not sure what other things would be needed for a boat, go fast and steer. Having more than one boat/car may be a thing I take on later so that could be a plus. I presume if I swap out the radio gear I would basically need all new electronics including servos as I doubt the ones that are in there would work with any newer RX.

Yes, you would need to swap out servos as well. The servos in your boat have the contact pins included as part of the servo wire connector. These were changed to sockets on the servos and pins in the receiver several years ago. Don't know why that switch was made, other than maybe the older servos weren't capable of working with the later systems. I know, with some servos, you have to set up the transmitter to work with that specific kind of servo. These would include some of the digital, coreless and programmable types. Just did some checking and found that the 3PRKA will work with standard or digital servos and, in the case of your boat, I'd probably go with the standard S3004 for the throttle and S3305 for the rudder, both due to how much torque they have. In my case, I have to use even more powerful digital servos, the S3151 for the throttle and S9256 for the rudder on my 1/8 scale hydroplanes but, with that said, your boat won't need anything with that much power to turn the rudder.
As for what other things you would need to operate a boat, some people prefer to have a remote needle valve so they can adjust the needle while running on the water. It's a nice feature but it also can come back to bite you if you change the setting and go too rich or lean. I saw that happen a few weeks ago, someone went too lean and it cost them a heat win. An on/off switch would be a good way to shut down a gas powered boat when bringing it back to the beach, if you want to use the ignition system to shut it down. Others prefer to shut it down using the fuel and carb, just something to think about as well |
