First of all, welcome home....

I have an identical engine, '77, 85 HP. They do not have the "tell tale" water spout. You can install one as the parts are readily available and quite reasonable. Due to the 2 years of inactivity, you will want to replace your water pump impeller and change the oil in your lower unit. It wouldn't be a bad idea to pressure and vaccum check your lower unit also. Then you can lube all the lube points and replace the spark plugs, then winterize the motor and then you will be already for spring!

Hopefully you will have some time to enjoy you boat before the weather turns sour on you.

Again, welcome back to reality and enjoy!!!
