WTB, Big Assed 12V Motor

[Doby]

I picked up a 40" tug and am looking for a decent motor (Brushed) to move this beast. Something like a Dumas Pittman motor or similar.

Anyone got anything stashed away in their workshop.

Must be in great shape and must be willing to ship to CANADA!

Let me know what you have.

Thanks

i have a 900 series johnson motor you can have if you pay shipping

I've got 2 brand new unused Kershaw Design 700HO brushed motors.

They've been my E-maxx spares ...but after I discovered brushless, I really don't need them anymore.

My dad has a tug in that size. He uses a automotive blower motor to power his. He runs forever on a battery charge, tons of power,been using the same motor for about 15yrs, and available at any discount auto parts store fairly cheap.

If you consider brushless, castle has their outrunners on sale cheap...down to 220kv. I know nothing about tugs so maybe I am mis-guided here but Im guessing you are looking for high torque/low rpm???

[kookie_guy]

I can get you one from work the size of a pop can, lol. Used to lift the rear hatch of a minivan. If that's too big, I can get ones that go in window regulators, or ones that are a little bigger than D batteries.

Do you know what the RPM's are at 12v's.

[sailr]

You don't need much rpm in a tug, just lots of torque to turn a big ass prop

Yup, thats what I'm looking for...TORQUE

I just picked up a 12V 12aH (SLA) battery that weighs about 20 Lbs, and it still needs more balast to sit on the waterline correctly

Thanks, but I think they are a bit high in the RPM range for my application

I'm going to keep this beast "low tech" as it just doesn't seem right using a brushless motor on a tug

I'll take you up on this as the price is perfect

But if anyone else has anything that might fit the bill, please keep the offers coming

I'll be checking that option out as well! Thanks.

Chummer, I don't know the rpms for sure' I will check next time I'm at his house and pm you. I don't think it's alot, the squirrel cage in a car does not turn that many rpm. The power it puts out is huge, he has pulled inflatable boats with 2-3 kids in it with power to spare.

Thanks Mark, I am interested in this one because it's available at local parts stores. It might be a good choice over the other one I have been thinking about. Looking in the 3000 RPM range to push a 65mm prop. Lotsa balls!

Doby, don't meant to hi-jack. Just a common interest.

[Doby]

The price is great, ,,,but 34 bucks for shipping!!!......thats where he's making his money.

[Punisher 67]

John I have two kenworth heater motors that have been ball bearinged , I once had a tugboat ambition and will maybe one day build one . the two Pittmans in the picture will be used instead . the Lehner 3080 is there for size comparisin and a 540 motor to the left

make me an offer if you are interested

[egneg]

The quest for large brushed motors can be trying. I have 2 that will go in a Dumas Donzi 65 that is 50 inches long. Here is a picture with some other motors for comparison.

[Punisher 67]

Sorry for the late reply John , both motors are about 325 rpm / per volt so about 3750 there or abouts on 12 volt
