1986 Mercury 75HP HELP!!!

[monkmonkey]

I need advise. My Mercury 75HP outboard only starts when I prime the bulb, wide open throttle, choke when starting. A bunch of smoke comes out when it eventually starts then no smoke. It won't go above 3000rpms at full throttle. It will eventually die. What may be all causes no matter how stupid it may seem. Yes, I do have full tank of gas.

Bad fuel pump.

I took my fuel filter off and nothing came out when I started the engine. Does that mean it has a bad fuel pump?

I had a similar problem with my 70 last year. It was the fuel pump. When you start the motor will it still run if you continuously squeeze the ball. Mine did, but when I stopped it died out only at half to full throttle.

Yea. I am going to replace the fuel pump. How hard is it to replace? Is it something anybody could do? How long should it take me?
