It is 10 horsepower. However, Chrysler engines never put out the same horsepower as Mercury for example. Mercury always under-rated their engines so their 9.9 probably deliverd 10-11 HP.
At any rate, the boat police will probably stop you because the badge says 25. The best thing to do would be to remove the logo and just run it as a 9.9. It is no larger than the 9.9 and indeed the hoods were swappable. In fact, in later years, I believe the Force 9.9 was a de-rated Chrysler 15.
HOWEVER. if you have a 15 inch high transom that you are intending to put the engine on, it will not give good results. And, it still may not give good results on a 20 inch high transom. As I said, these engines were specifically designed for the high sailboat transoms. They were designed to deliver high thrust at a lower speed to move a displacement hull and were not suited for a planing hull like a flat bottom jon boat. They are excellent kicker engines for emergency use or trolling a boat with a larger main engine. However, it is possible to by a regular lower unit and swap it onto it. Look for them on the auctions. Almost any 9.9-15 Chrysler lower unit will swap right on with little to no modifications.
If you get the model number, someone here will tell you the year it is, although for all purposes, the engines were the same for a good number of years. Looking at the hood and midleg design, that engine dates somewhere between the mid 1970s and early 1980s.
