Hello everyone I am new to the forum and have found some great info here thus far. As for my problem I have a 1978 mercury 40hp 402. I just recently purchased this boat took it out a couple times and noticed a lot of fuel spewing out the back when I started it along with just sitting in top of the motor. Also it did not seem to want to stay running at low idle. I do not know to much about boat motors so I took it to the local marina. They told me I had a fuel line leaking so they fixed it and also put 2 new plugs in. Well I go and launch the boat today and at low idle it is great once I was out of no wake zone and start to increase throttle it gets all crazy. From around half to full throttle it will start to go then bog down then go again. It just revs and takes off then down then back up. I'm just really confused on how it ran amazing before at full throttle and now it's not. It does not die at full throttle or even act like it wants to it just won't go. Any help or suggestions would be greatly appreciated and thank you all in advance.
