Welcome to the forum PTC.
I suggest you post the same question up in the Force Repair area and you will get a little more specific feedback. There are some very knowledgeable people in there including Frank Acampora who can shed some excellent light on this for you.
As for myself, I have a 90hp Force on my Bayliner and have absolutely zero complaints. It runs great.

You are going to get negative comments about the Force motor and some of the guys in the Force area will be able to tell you why....very interesting and a lot of it is a bit of a myth.
Regardless, what you should be looking for tho' is a well maintained motor first and then consider brand name association second.

The motor should be compression tested prior to purchase. As well, I highly recommend that you push for a water test or in lieu of that a highly reduced price....just in case something is wrong with the boat or motor.
The motor can be run somewhat in the driveway with some 'muffs' on it but that is only a minor preliminary test. It doesn't help with the function of the lower unit, high speed, top speed, etc.
Again, post your enquiry up in the Force area....you will get some excellent feedback.
Good Luck
BP
