I recently have picked up a boat with a 1994 Yamaha 130hp on it. The engine sat for about 2 years before I got it. The engine was recently serviced and they had to rebuild/clean the carb and fix a pin size leak in the fuel pump. The person I got the boat from said just before the boat sat the engine had a complete rewiring done.

When I put my boat in at the dock in the morning my engine some times will start after about 5 or so cranks, or will just sometimes leave me scratching my head before I use a few sprays of engine start. After that my engine has no trouble starting throughout the rest of the day.

What could be my problem? I also put new spark plugs in when I got the engine.
 
Those 2 stroke carb'd yamahas are choke reliant when cold. How are you operating the choke, and is it operating properly if it is an electric one? I have had a lot of them and the process is always teh same when cold -
1) pump the fuel primer hard
2) Lift the fast idle lever to 1/4 - 1/3rd throttle position.
3) Engage the choke (press key, pull knob or however yours works)
4) Wind over engine
If it doesn't start within a few winds, go back and reprime then try again.
Has worked for every carb'd yamaha that I have tried.
