WEED WACKER MOTOR

Postby DUCKANDBUCKAHOLIC » Wed Sep 21, 2005 9:05 pm

IM BUILDING A MUD MOTOR OUT OF A 32cc WEED WACKER. WHAT IM DOING IS TAKING OF THE WACKING PART AND PUTING ON A TROLING MOTOR PROPELLER. ON SOME WEED WACKERS YOU CANT DO THIS. I KNOW YOU CANT ON CRAFTSMEN. WELL YOU COULD BUT IT WOULDNT BE AS EASY. I WILL SOON POST THE PICS AND IF ANYONE WANTS TO TELL ME IF THEY MADE A MOTOR OUT OF A CRAFTSMEN WEED WACKER TELL ME, AND TELL ME HOW YOU DID IT. :smile: :thumbsup:

What kind of boat are you going to be using it on? And how fast could a weed wacker motor push a boat? I'd imagine is would be about the same as a trolling motor, right?

I would think a little faster than a trolling motor, but I could be wrong. Those little 2stroke motors can turn some pretty big rpm's.

Half the problem will be matching a prop with the motor. If you use a trolling motor prop you probably won't go any faster than a regular trolling motor would push you. If the weedwacker has enough muscle to push a small 3-5 hp prop you might have something. Remember, it doesn't matter how fast you spin a prop, if it's a low pitch prop you're just wasting fuel.

Isn't that week wacker motor going to be really loud? If i used a weed wacker motor where i hunt i would be shot going across the lake. Lets see some pictures I gotta see this. I hope it works :salude:

Agreed, I'd like to see this too. To me, it seems like it would be making alot of noise, with not alot of "go". I'd think that just buying a trolling motor would make more sense. I could be wrong though.

I did this last year to push a small skiff around. The motor was a Ryobe, the prop from from a trolling motor. The problem is the centrfugal clutch. It will wear out very quickly, cann't handle the torque.

Send my your email address, and I will send you some pic. Heck, pay for postage and I will send you the prop end, I kept the motor after replacing the clutch.

the 2 stokes put out some RPM's, but how well do they handle the load? it would seem that it would bog down rather easily.

hmm...interested in some pics and a run down on how it finally worked. it has some possibilities.

I TRYED IT OUT TODAY AND IT DID PRETTY GOOD. UP UNTILL THE POINT THE TAIL CAME LOSE. BUT THAT WAS ONLY BECAUSE IT WAS LOOSE IN THE FIRST PLACE. THE SPEED WAS A LITTLE SLOW BUT, IM GONA TRY PUTING ON A BIGGER PROPELLER. OUTHER THAN THAT IT WORKED PRETTY GOOD. THIS PARTICULAR PROP WOULD WORK GOOD WITH A SNEEK BOAT. BUT AS FAR AS A 16 FOOT JOHN BOAT IT WAS ALITTLE SLOW. :thumbsup:

most weed wackers are shaft driven by a flex shaft and lightly attached and not made for that kind of load. I bet this is one of the first things to fail. 30cc is also about 1.5 HP and maybe a 40 thrust motor with the correct prop.

IMO failure rate might be a problem as well as noise. The only up side it lighter weight from not needing a battery.

Yeah I just got done working on one of these the first problem I came across was the motor would totally shut off once the propeller was in the water so i took the coil shaft out and got a 1/4" steel rod and then cut the shaft of the weedwacker straight but now it vibrates to much and the rod falls out inside the weedwacker Im still working on it might buy another rod and try it again but I dunno i think its just easier to use a outboard :smile:

I dunno about his but I gave up for this season maybe this coming summer when i have some time on my hands I will buy another peice of rod and try it out again. I cut the rod to short my last try and the rod kept popping out when it would get started.

The weedwacker runs high rpm with low torque. The trolling motor prop needs low rpm and high torque. To be efficient you will need a gear or belt reduction to increase the torque to the prop. Been there/done that.

I would love to see a boat come motoring down a river with a weed wacker engine. Does sound like a good idea though. Just not worth the time making it work.
