Pulled out my Rare Marauder Hovercraft


This is the a Hovercraft I brought years ago. It was designed by Whiteman Industries. Just pulled it out of the attic and dusted it off. It has a O.S. 61 engine in it at the present time and was very fast on both land and water... only problem was... too noisey!!!
This thing was very loud. Was wondering if anyone else out there has/had one. I'm thinking about converting it to electric.

Thanks! As I said, I'm considering an electric conversion for this machine. But I have to admit that there is something to be said about this sweet loud motor kicking up a ton of dust and asphalt while zooming across the roadway, or water. There is a you tube video of one. I will look for it and post it.

Sounds great! Know what kind of Motor you are going to put into it?

Most likely one of the new brushless motors.... the only issue is how to mount it. The IC motor in there now is held in by a traditional ic horizontal mount. that is completely different from the one that I need. The other issue would, the placement of the battery, especially if I intend to operate it on the water.... Right now, there is a compartment to the rear of the engine that is below the exposed servos that also houses the battery pack that drives the servos. Problem is, that the battery I would require would be much larger and may not fit in the same area. Have to do some investigating!!!

Nice shape yours is in!

I still have mine, I built it in 1990, if I recall correctly. Mine is powered by a Fox .74 Eagle.

I don't think a brushless motor powerful enough to move this beast will be much quieter than that glow engine. It's mostly prop noise anyway since the engine exhaust goes first through a muffler and then through all that piping to the rear of the craft.

I intend to restore mine some day. It was a lot of fun.

Well, I thinking of a brushless motor with a reasonably high KV that also allows me to get the most out of a 12" prop, which I think is the largest size I can fit in the housing.

Thanks alot "airbag12"... Unfortunately,I haven't gotten around to converting it yet. I have been working on other projects. Actually I am considering selling it in order to let someone else enjoy it!! But thanks for the compliment. Ken!

I think I am going to build a foamy electric version of this but I have a question. What is that little intake on the back? Does that have to do with the airflow in the skirt or does that have to do with the glow motor?

LOL, my foamy electric version got wings. I guess that's what happens when you drink to much rum while building. I am going to do a build log on it here:

Hey there, that little intake on the back is designed to force the air from the 12" prop along the sides of the airboat and out towards the rear. It actually has the effect of tunneling the air so that it is more concentrated than scattered... as a result the airboat is able to move forward at a pretty quick pace. and the three rudders assit greatly in turning.
