Personally I would stay stock. I've played with these, but Mercs can be merciless when doing, or trying to do retrofits. I know a guy with a boatload of these beauties, I will try to track him down. I have a few Super Sixes around and a Mark 30, Mark 35, and some boxes of assorted parts.
Yes, it will fit and work a HELL of a lot better than the Skinny-Tilla setup. Done several of them of them.

PS: Good that you got the points cam with it--hard to find.
Sweet, I love these motors. They are so compact and powerful. Used to race my Dad with the 1957 Mark 30 on my boat.....16 ft. Cadillac, and he had the Evinrude Lark 40 tiller on a 16.5 ft Alumacraft Yukon. I could "dust him". He had the same 10 horse as yours but could never keep it running. Finally lost his wrist watch in the lake while pulling it over in a frantic rage. We were in the middle of the lake. He started loosening the motor and going to drop it in 30 feet of water. I cried and pleaded with him, He looked at my tears and didn't do it........I ended up with the Merc 10, eventually fixed it and got it running beautifully. I was 11 years old. Sold it for 175 bucks. I had outboard fever......never lost it.......51 years later, still love 'em.
Very cool story. I go way back with the 20 C.I. Mercs. I remember one day when my dad and his friend were racing on Keuka Lake in the Finger Lakes of Upstate New York. My dad's friend had a Feathercraft Firefly with a 10 H.P. Hurricane on it. My dad, mom and myself were in a speedboat called a 16 'Mullins inboard boat (I bet none of you know what that is) he couldn't beat my dad even when he sat on top of the Hurricane. I then rebuilt a Mark 20 when I was about 17 years old and put it in a Minimost homemade boat (7'). When I hit the throttle the boat would literally leave the water. What fun.
I'm lucky to have found this little engine.
Cheers,

Heck, my Uncle in the 3 lakes Wisconsin area had one I am pretty sure it was a Mullins, not a Chris Craft. He invented and created the Trindle Arc Welding Company. His mama was Joe. He would give us rides in that boat. I was about 7 years old. Talk about fast? You are not kidding. I'm gonna call Joes Brother in law, my Uncle John who is 84 years old now....and see if it really was a Mullins. It wasn't really a boat, it was "art work".
Ha.....great history too. I really don't remember the hull, but it had plenty of wood above. The design of the hull on Joe's boat seemed flawless. He ended up selling his business to another welding manufacturer, they changed the name. I still have a 175 amp Trindle welder up at our remote NW Ontario resort. Its quite possible he sold out to Lincoln, I think at the time they were based in Illinois. Joe was a real "clown", quite the personality. He ended up fairly wealthy. I learned how to weld with his equipment. Now after over 50 years, I am specializing in small project, marine mostly, aluminum and stainless MIG. Use a Miller 200. Do props too.
We live in Duluth MN. Been here my whole life. Have 2 camps in remote NW Ontario, since the early 60's. One on Lower Manitou Lake, 40 miles due north of International Falls MN, and the other on Big Canon L. 30 miles NW of Vermillion Bay Ontario. Drink excellent water directly from these lakes, so pristine.
