Hi good idea, have you been out on the water yet?

I have several 12 -18 volt motors the size of a 550 and run them on 6 -7.2 volts and they will turn over a big prop 45 - 50 mm.

This looks good on a cargo ship where you can almost watch the prop turn over. They do not get hot and have a low current drain. Bonus is they are often cheap! Also I can use slightly cheaper NiMh batteries of about 3300mAhs.

I have a few Pittman motors originally scrounged out of computer tape decks 40 years ago. They are almost silent and work really well.

I always check for hot batteries or motors as I do not want current diverted from the motor to heating up the drive train.

Following a friend I have also found a cheap and effective and silent U/J. It is plastic flexible tubing about 3/8ths inch diameter in less than 2 inch lengths.

You can use it in place of the Huco U/J, keeping the brass inserts on which it is a tight fit. Or if you have a threaded shaft a largish pair of nuts locked together with the tubing forced over them.

They need to be in a straight line and a few fast forward and reverses settles the tubing into position. The drive is silent and efficient and good for up to 20 watts or so.

I would agree with others, viz. use a smaller prop. When a motor gets hot it normally indicates too high a resistance from the prop, so try a couple of smaller sizes and monitor its performance.
Good luck😉

Ronald, Nice little build

Wooden boat magazine is amazing, beautiful restorations, new builds and general information. Well worth the money

Ronald, the prop is actually 1-3/4" ... in the photo you hav indexed the left blade to the end of your ruler, not the "0" point on the ruler. My 33" PT109 calls for a single 1" plastic prop to reach scale speed. I think you need a smaller diameter & much less pitch to alleviate your motor heating issue. Heatsinking, & watercooling or a fan will not fix your issue.

She certainly handles well in the water. That would be a nice one to enjoy cruising around with. From the video it looks like the velocity is more of a speed boat rather than a dory.
Nice job!

Maybe you guys have heard of the Imai (Japanese company out of production), but you can still purchase the model Through:

The rest of the pictures.

Looks a lovely pond, like the maneuvering challenge. How big is it ? It’s made me thinking about building one for our club.👍

That looks like a wonderful day to enjoy. Having a continuous audience of spectators and possible new recruits is a big plus!

Chumm444 Yes I also use Callie

Well on you. 👍 Callie is the greatest! Some graphics she recently did for me.

Looks like a fun day, I'll have to try to make it to one of your events

Any more photos of your St Pierre dory? Looks like a some fine boat.

Simply...

Sweet!!!!

Great Job, Mate!!
Great Lighting!!
Great Sound!!
Great Videos !!

Gewoon prachtig😮👍👍👍
In all the basics very similar to my Southampton tug - gives me some ideas😉 Thanks.
Cheers, Doug😎

!Great idea, I love it!🤔
Is it something that remotely you can control or is it on at all the times?
How long does it take to start smoking after you power it ?

Good question I could put a switch in one leg of battery to turn the simulated smoke on & keep the switch on the unit one & the fake smoke will come on right away I think haven't tried out yet but its easy to turn on after putting main battery in & putting plain water in the humidifier tank .New plan took it to Spencer's pool & wire broke off U.S.B. plug .Rewired used battery port on Flysky Receiver which is about 6 volts to power up the humidifier & it worked .

Good looking tug👍

😍😍😍😍😍
Congratulations, a very beautiful model
