Hi, I recently purchased a 1989 Quantum Fish and Ski that has a 89 Force 150 Hp on the back. Yesterday I put about 3 oz of Stabil Marine in the fuel to help keep it fresh. I fired up the motor and it started on the third crank, it smoked a little bit but not a lot, I let it run for about 5 minutes to let the stabilizer work through the fuel good. When I shut the motor off I noticed there was a lot of black oil mixed in the water tank I was using. I tried to start the motor again and it would crank and act like it was trying to start but never would. I thought I may have flooded the engine but when I tried to restart the engine today it would crank but not nearly as good as yesterday and never started. When I pulled the the prop out of the water I noticed a ton of oil around the back part of it. The oil seemed to be leaking though the shaft that is above the prop. I have included pictures, I just hope the engine isn’t blown, thanks for any help or suggestions!
