O.S. engine?

[marleybone]

Anyone ever heard of the o.s. 90 sr-m abc? Never heard of this edition nitro engine before. Thinking about putting it in a scarab 55". With the donzi project coming to a close, need to focus on some other endevours!

I think it is a discontinued motor but its for sale on ebay. I spoke with the seller and he said it was a 80's to 90's engine.

LOL.. well found Kmot... I only went back to 1980... :o

I'm blown away kmot! I cant believe you found that! Now my next question would be do you know anything about this motor like the specs. or its application?

No, but your best bet is to go into the gas, nitro, internal combustion boat forum and ask there. The old timers will know.
