i just bought a 18ft lund with a 1982 mariner 80 hp
it starts a little hard (i can deal with that) the trouble is when it is warmed up
i put it in gear and the motor dies.
if i put it in gear and give it gas fast then it will go.
but if i leave it in gear at idle the motor will die.

please help me

You want magick. Tell me what's wrong with no information.

What is the mechanical condition of the motor?
Compression check at a minimum, leakdown test for more info.

Is it getting too much fuel, or too little?
Quick test, if you pump up the bulb, it should get firm and not give. If it gives, look in the carbs while it is and see if one is flooding. If it is, you have found your trouble.

What is the condition of the fuel pump, filter, hoses, connectors, etc.?

Is it properly timed (link and sync)?
Improper throttle pickup timing could act like this.

Is the lower unit in good condition?

hope it helps
