One more thing, The carb was rebuilt about 4 years ago.

I have a 94' Mercruiser V8 350 engine in my boat (21' chaparral). For the
past year I have had some difficulty starting it. I dry dock it and when I
start it up on the hose in the beginning of the weekend to make sure
everything is working before taking it out, it's extremely difficult to
start, I usually have to put it in neutral and pump/push it forward and
back maybe 5 times then almost put the throttle all the way forward for it
to start (and still it has to crank for a about 5 seconds before it
starts), once started i run it at maybe 2000rpm for a minute or two then I
can put it back to idle and no problem. If I let it run for a while the
next time i go to start it, it turns over perfectly.... Now when I put it
in the water an hour or two later, i have the same problem except it is
magnified and more difficult to start.

Things I have done: Check the plugs / regap, outdrive serviced / impeller
etc...

My thoughts are that it probably isn't the plugs because I would have a
difficult time starting it weather it was warmed up or not correct?? I'm
thinking maybe something in the fuel line putting gas to the carb? But
then why is it more difficult once it's in the water?

Any troubleshooting suggestions is appreciated!
