I have 1500 merc inline 6 cyl
I have 1500 merc inline 6 cyl.When you take off its slugish and takes it a bit to get on plane when i get out on the lake it doesnt seem to want to open up to full rpm it will get to about 4200 rpms and after about ten minutes of running it just dies out in the water and i have to idle back to the ramp. When you try to give it gas after that it wants to die. I have checked compresion 110+ on all cylinders. There is not 2# difference on any of them. I checked to see if all plugs are fireing and they are good and hot. I have put in new needles an seats in carbs because they were leaking gas and that fixed that. I have put all new gas lines on it and that didnt help. I found two wires coming out under the fly wheel that the insulation was cracked and were touching and fixed that but no change. I used carb cleaner sprayed in carbs no change. I put new plugs in also. It will idle great.
