Help with Evinrude XP150

I've got a '85 Evinrude XP150. It has sat for a couple years but ran great (of course) when I parked it. I recently had the carbs rebuilt supposedly. It runs no different than when I took it for this to be done. The dang thing runs like a champ on the hose but drop it in the water and it won't. I finally got it off the trailer last weekend and it would push my boat at about 8 mph. So back on the trailer and back in the back yard. Is there anyone around that can and will still work on this thing?

fuel pump, air leak in primer bulb or fuel hose, fuel hose collapsed inside due to ethanol....

We can check it out for you

The bulb is new, I am going to replace all the fuel lines next. Perhaps I can find a pressure gauge to check the pump. I just think it may be something bigger. I do feel like it is a fuel problem of some sort.

Edit to add that the plugs are new as well.

I left a voicemail for you!
