I have a new 50 hp 2 stroke. Ever since I got her, she's really tough to start the first time. After that, its not a problem the rest of that day. I am just through with the break-in period and she is running on fresh gas. Any suggestions?

Tilt engine down all the way, pump up primer bulb till firm, start engine at idle speed without giving it any throttle at all.

If this is a newer model 50 it has prime start which is an auto choke system and is not connected to key switch choke.

Opening the throttle plates lessens the vacumn needed to pull fuel through prime start system.

You can research my previous posts, I had the same problem (S)
Mine boiled down to fuel hose routing, bad primer ball ( 4 0r 5 of them) I currently have a Evinrude/Johnson/Bombomdier and it works great.
Also the boat mounted fuel tank anti-siphon valve was removed.
Lastly a low (but still cranking) battery will cause the starter to drop out (during repeated start attempts)and make you think it is not getting fuel .
I checked all of the book carb settings and all were OK
I also changed all of the fuel lines and the 50 micron fuel filter.
All seems well now.
Cheers !!!
