Hello There
This is my first time posting, I have a 1985 115 Mariner on my first boat. The problem is that when running on idle the engine is (a) Very smoky and (b) runs very rough yet on full throttle the boat is very fast. So i guess my question would be how can I solve this and also can anybody advice me what the ratio of oil to petrol would be??
Many Thanks
