Yep it's a hectoperm same as pic.
6 or 12v still none wiser but it runs on both but a bit sluggish on 6 to fast on 12

Just to remind me did it turn out to be a Hectoperm? They made 6 volt and 12 volt versions of both motors mentioned. If you think 6 volts seems better you probably have a 6 volt version. The 12 volt versions are just a little more efficient than the 6 volt ones.
It all hinges around the brushes and the voltage drop. It is simple arithmetic, will explain if interested!

Well took tugboat out for a run yesterday and happy to say she's watertight and sits well on the pond..Tried a 12v battery and she run fine with no issues but a bit to quick. Stuck a 6v on her and she ran much better. So 6v running it is...

Thank you i found you on Facebook,however im not on FB so was able to view only a very limited amount. Good to find a Canadian source, thank you for your kind reply.

I operate as 'Greg's Model Boatyard ' molding and selling Fiberglass Hulls, Hulls outfitted with all R/C gear, and finished models too.
I do have a large stock of Model Boat fittings, power and R/C equipment, and building supplies.
I am located in New Brunswick, Canada.

You "have sold"????? Are you a hobbyshop? I don't understand.
Context question

These are great gear-motors, known as Decaperms.
I believe they are rated for 12 volt, and your ESC is also rated for 12volt, they were sold in North America through Horizon Hobby
I have sold many of these over the years.

This motor I have is two and a quarter inches in diameter. Including shaft 6 inches long and has 5 screw slots each side and power connections are just pins

While all this has been going on I have been working out why my trusty Sea Jay copy with the Bassett-lowke Marine motor did not perform.

After much testing, the smoke was coming from the motor but suspected old esc which proved to be OK. I had a spare BL marine motor so fitted that. But there was a mis-match of RC crystals as well.
I am on 27Mhtz I call it staying in character, others know I am reluctant to throw away perfectly good but dated equipment.

So coffee and a sit down while I get my eyesight back to normal.

Hi Colin I have looked at my decaperm and the A & P line up with the V underneath. That is in agreement with your point. I am not going to contest it as there were a few variants but the diameter should resolve it.

When I think about it my old Hectoperm, long gone now, was more than 4 inches long and bigger altogether.
The Decaperm in my hand now, has 4 slotted holes each side and the pictured one has 5, interesting!

The text is DECAPERM in capitols with 6V under but central and below that max 7A

regards to all.
Roy

Terry, if you look at the top of your motor it has some letters left from the original label, I can see an A and P which can only be a Decaperm as none of the others have a letter 🅰️.
Cheers Colin.

My "mechanic" has just replaced that exact same ESC in my balloon buster as it was intermittent. VIPER 10 replacement, 7.2V NIMH

Until today it was just a brushed motor that came with the boat

Looks like monoperm which would be 6 volt
😊

Hi scratchB. Marx used to produce a whole range of motors microperm, milliperm, monoperm and the monoperm super. There was a duoperm but I have never seen one. Then Deca and Hectoperm.
They all had a family likeness, used to be orange and black, then went to all plastic and just grey.

The smaller motors often appeared in 'servos'. But these servos were really actuators from pre proportional days. Then an actuator might be clockwork or rubber driven.
All back in the day as they say.
Roy

There were I think 4 motors in the series, Milliperm, Monoperm, Decaperm and Hectoperm...

Guys.
In all my years I have never heard of these motors.
Just goes to show you learn something new every day.
Are they rare and sought after?
Thank you
Bill 👍👍

Hi just remeasured my Decaperm and it is 3 inches, check the diameter my one is 1 3/4 inches dia.
There are several versions of these motors right back to when the series of motors were orange and black.
I agree with the comment of being reliable though.
On the 3rd. original photo there are 5 mounting holes which does suggest the Hectoperm motor.
When the Hectoperm motor was last on sale it was £163 not a realistic price at all.
Roy

Hectaperm has 5 or 6 mounting holes each side, Decaperm has 4 each side...

Thanks Terry.
Looks good,and has a lot of potential for you 👍👍
Bill

Sorry been out..
The boat is based on London Tugboat SunXX11
I tried taking a pic of the inside as to me it looks like it's been carved from a block of wood and is quite heavy with a tiny bit of lead on the sturn

Oooh Hectaperm, nice motor! I think the run on both...

Hi I have just measured a Decaperm and if the body is 3 inches long then it is a Decaperm. If bigger then it is a Hectoperm.
Roy

Hi Terry.
Could you possibly post some more pictures of your new acquisition.
She looks good,so would like to see more and follow progress.
Regards Bill.

By the way what is the boat looks familiar

I’ve one of these set up it’s 6v use a lead acid battery it’s a good set make sure the gears are clean I use brake cleaning spray and oil with very small amounts of light oil

A good day
I have been using Marx decaperm en hectoperm motors in all my boats and they are just FANTASTIC
Never ever had any trouble with them

Thanks for the help peeps. Appreciate
Regards Terry

Hi Terry
The motor is a geared Deccaperm. There were 6v and 12v versions and your motor has had the voltage erased so you will have to try with both sized batteries to see which best suits your model and motor. The Esc is I suspect a 12v max 15 amp and not known for their reliability especially if used to their max rating.
Judging by the wooden tray behind the motor an SLA was probably used and my guess would be 6v 10amp.
In the 1960's and 70's the Deccaperm motors were possibly the best and certainly the most expensive motors available. They are however very early versions using technology available at the time. Modern motors use much more powerful magnetic material and modern construction techniques produce much greater power than was previously possible. The Deccaperm had a very good if noisy gearbox which greatly improved the output power of the motor.
Chances are the motor and Esc will work fine and as long as the shaft is oiled/greased and free running you could be afloat in no time.
Plank on frame can be prone to leaking, especially if they have been stored for some years, so I suggest you float in water for several hours to find any leaks before you submit to the local lake.
In its present form it is certainly a classic of its time and it would be a pity to replace the original set up for a more modern system if it is all still functional.
Looking forward to hearing how you progress.

Hi Terry, that's definitely a decaperm, and will run on 12 volts without any issues. I have one in a tug for over 30 years and still runs sweetly.
Cheers Colin.

Hi
The ESC is very much like the one that I have, and that runs on 7.2 to 12 volt, as for the motor it could be a Decapum (sorry for the spelling) a very good motor.
