Mercury 40hp 2 stroke oil injection
Hi, I just bought this engine, compression is good on all 4 cylinders, the boat is really hard to start and it will only start with fast idle lever up right or with a lot of throttle apply. Once started i can't have it at idle with the fast idle lever upright otherwise it stall. As for power, i have 14.5 ft bass boat and at wide open throttle I can get up to 6.2 miles per hours. If I am at low speed and go wide open throttle there is a lag and it seem like it wants to stall but it does not stall. There seem to be oil/gas on top of the bottom carb. And it burn 3 gallons of gas for 3 hours of trolling at low speed and I was wondering if it's normal consumption. Can anyone tell me what to look for since I live far from any mechanic. I have good basic engine knowledge but i don't want to start tearing it apart if i don't have too.
Spark plug are good. Thank you very much
