Motor dies when put in gear

[mercgirl]

I have a 1970-something 70hp motor that sat unused for about 3 years. It seems to lack power when I start it and increase RPM, but it dies as soon as it is put in gear. I tried to give it full power quickly but to no avail. Could it be a leaky fuel line?<br /><br />Prior to its neglect, the motor ran perfectly for years!

Re: Motor dies when put in gear

Are you using fresh fuel ? Mixed at 50:1 ?It does sound like a fuel related problem. <br />After 3 years, it will need 1.Waterpump kit 2. Carbs cleaned 3.Change of gearcase oil.
