Glow outboard display by Mark Booth. This was the last video segment in the order that I shot them, so you'll hear us saying goodbye to Tomahawk. But it is up near the start of the playlist for viewing, so there is plenty more to see. You will see Mark near the middle of this video, and at the end you will also see Todd and Claudia Radmer.
Here is Mark Booth's description of the display:
I was asked by Denny Cole to do a write-up on my collection of toy gas outboards I had the honor to bring to the show.
As a quick history of why I collect just the toy gas outboards, I started to collect the electrics and gas then soon found out there was way too many electric outboards to collect and have the room to display them. So, I decided to sell off all the electric outboards I had and just focus on the gas only. In time I began to prefer the gas over the electrics. As a guy that works on all types of engines, I came to appreciate the mechanical ingenuity of the gas motors.
I currently have 62 different gas outboards in my collection and they were all on display at the show. My research has documented over 100 different types including variations of similar outboards. Even this is not a true representation of all the variations out there.
The first question most will ask is, how many manufacturers were there of the toy gas outboards. Here is the list as I know them… Fuji, Atwood, Allyn Sea Fury, Red Wing, Super Tigre, Wen Mac, K&B, AMPS, International Hobbies, TMP, OS Max, Thunder Tiger, ABC Hobby, Dolfin and Academy Hobby Models. This list is in a loose order of oldest to newest. My list does not cover custom manufactured outboards or the new “Weed Wacker” engine powered outboards. I am trying to limit my collection to just the major manufactures.
Displacement for the gas outboards can be as small as .049 to the big K&B 16.4cc glow engine. Some one may ask what is a “Glow Engine”. In its simplest definition the spark plug on a “Glow Engine” has a fine wire in place of the standard gapped plug. This wire will glow red from the heat of the engine running which in turn ignites the fuel and the process continues. Thus, the name “Glow Engine” or “Nitro Engine” based on the fuel burned.
As for getting the power of the engine to the propeller there were only 3 ways to do this. Spring Drive where a spring is attached to the engine and then to the propeller shaft. The spring was able to make the bend to the propeller shaft. Next was the use of gears to make the 90 degree transition from the engine to the propeller shaft. Lastly is the design used by ABC Hobby and Dolfin where belts are used to transfer the power.
