K&B 3.5 Ducted Fan

Postby iamplanecrazy2 » Wed Mar 10, 2010 3:33 pm

I have a K&B 3.5 ducted fan engine. It has rear drum rotor induction.
The engine is fitted with a gold anodized carburetor and the case is
stamped K97 3.5 on the side of the mounting lug. I thought the K97
was an outboard engine with a gold anodized head and carburetor.
Were any K97 ducted fan units produced or is my engine a mix of
outboard and DF parts? If it is a mix can I expect better performance?
Thanks,
Tom

I believe the marinf an ducted fan motors are basically the same motors with the exception of the air versus water colled heads.
