It dose not take much! Going for # 106
Bottom, the 4 ribs, the hull sides are all cut out. I did change the design slightly and made a separate motor mount. Ribs are mounted on the bottom and the stern tube and shaft is fitted. The motor mount is done.
I’ll get some pictures this week end as I hope to have the hull finished along with most of the cabin.
I'm thnking engine sound, horn, and running lights.

Finally! My Proxxon DS230 arrived! what a gem! this little baby makes quick work of 3mm ribs and 1,5mm planking. I will post videos and photos soon so you can all see what this little workhorse can do. And quiet as a church mouse!

Did a bit of work on mine this week end. I did change the design a little. I am hinging the front window. The seats are done, drive mounted as is the rudder. Sunday morning I started painting.
By the way mine was cut out with just a box cutter knif.
lookin real nice! I got my saw last friday just been busy with work. Mine's not a flat bottom, it still has a box keel. I was out yesterday on the neckar for 2 hours with my springer, managed to push in some plastic bottles floating by and watched a mother duck with 4 ducklings playing around the kayak launch dock. Heres a few renderings I did when it was too late to make noise with the saw.

I'm taking my time with this one, I have the next 50 years or so to perfect it. And to me thats what the design is all about, perfection. And design is how I make my living.

hey gill I like how you built a wood motor mount then secure it in the hull with screws, I was trying to figure a way to do something like that with my 45cm flat bottom fishing hull, and ended up with a plywood plate that the motor is screwed to, then slotted into a pair of grooves in the adjacent longitudinal frame members. Needs a screw or a dab of glue to secure it, not as serviceable as your design.

I use a variation of this mount in a number of models.
1/8 lite ply (aircraft) I change the angle to match the drive shaft angle.
I place at lest 2 layers of ply in the bottom of the boat, for the mounting screws. The screws I use are #4-6 3/8 - 1/2 inch long.
I have all so used this for 7-800 and 900 motors. Just make it bigger.

I have mounted this on risers in deep hulls.

Hey Gill, I've looked all over for 555 electric motors, where do you get them? are there some advantages over a 500 or 600? and do you use lead acid batteries or always nicads?

The 555 motors are from trains. I run gel. 6&12v, nicad, hydrid, and lipo.
The 555 motor is a 5 pole runs much smoother then the 3 pole motors. It also has much more torque and in most cases draws less current.
I can push a 45 mm 4 blade prop and only draw about 1-3 amps, no heat.

Tell me where I can find them! i suppose they're a bit harder to get over here than in the USA. Who makes em?

I get the motors from hobby shops that handle trains. They are replacement motors for G and O gauge trains. I have even purchased used motors that were not the best for the train but work fine in a boat.

Hi,
they look really good, nice low RPM that will drive the prop suggested,

I don't agree that they have more torque than a 3 pole motor, only that they have enough torque to drive that prop at that RPM

Cheers

Don't take this wrong because I love the tug....but with that big ole keel added...it's no longer a "flat bottom" tug...

Never mind...I see now that its jlepinske's tug....nice tug dude!
