Storing a Yamaha F90 on its side.

[MichaelP]

I just purchased a used 2012 Yamaha F90 from a marina and it's laying down on a pallet with port side up. There is nothing in the manual on this topic. I read that the portable Yamahas can be stored on either side but what about the midrange motors? I haven't been able to find landing pads or "this side up" markings. I'm hoping that the marina didn't screw up.

The plan is to use this to repower the 18" Chieftain shown in the link below and really hope it's not going to be too heavy. (366 lbs vs 250 lbs)

Thanks
Mike
