Very nice old Enya 60 6-bolt with original factory "carb" - circa late '50's, very early 1960's. The "muffler" is actually just a duct, but also factory original

This one would definitely be the oldest engine we have ever seen......
"........this one was built by my Father in 1088......"

His father lived a very long time........................ From ebay:

Hi,
Do you know where I can get one of the exaust ducts? The one on my ENYA 60 is missing.
Thank you.

Sorry, I can't help - I only have the one NIB 60 myself. Like flexi needles and tanks on Frog 500's, they were the first things discarded

Probably confused by the fact that it has 15 D written on the side, this seller thinks it may be a conversion from the Max 15 Diesel. However, it is the genuine glow version (note the head with the offset plug) even though both engines share the same basic crankcase. Its official title is the OS Max-D 15 Racing Glow, dates from 1961 and is now, I would think, rarer than its Diesel sibling (which was a bit of a flop, but collectors don't care) Chinn's test here

The genuine Diesel Max-D on the bottom row for comparison - note that it has the word DIESEL spelt in vertical letters between the exhaust stack & lug

WEBRA 1.8cc GLOW ENGINE FOR MODEL BOAT USE
ENGINE HAS 2 : 1 REDUCTION GEAR WHICH ALLOWS THE ENGINE TO DEVELOP MORE TORQUE TO TURN A BIGGER PROP.

Browsing old catalogues, it seems to have been sold as late as 1964-65....here, as a standard part of the marine version.

Bosse, correct ! That old 60 was sold pretty much right up to the time that the Enya 60-II Model 7032 appeared in 1965

" Profi 0.49 Combat Glow engine. This unit is one of the first series of these engines and was produced (I believe) somewhere in the 2006 - 2008 timeframe. This engine has an identical mounting pattern to the Cyclon 0.49 and features an AAC piston/liner assembly and uses Nelson glow plugs. The unit is very highly timed and will respond best to props with no more than 3" of pitch (2.5" may well be better). Please note a pressure fitting (Super Tigre) has been mounted in the back plate "

Would you believe it ! Just when we thought we had found the oldest engine (shown above, 1088) known to Man, along comes an even older one (by 22 years). Incredible !

I can see their smiles when they - finally - found a use for The Holy Glowdriver...
