I would like to know the valu of an OS FS90 & an FS91 SII-p. Both are new in the original boxes & never been used. Any comments?

thanks

$200+ or - $50. Depends on the market that day. You could get more but it is rare; enough around to not be rare.

Sorry for the misunderstanding. I'm looking at buying one not selling.

I go by 1/2 of the new price. Less if it looks rough, and more if new in box. Lately $20 seems to be getting me a lot of pretty good nearly new smaller 2 strokes.

The 90 is a good running engine, but not a power house compared to the 91. The 91 being pumped is great until the pump goes out. Cant get a new pump from OS so you have to do legwork to find another. Both are good engines.
