Welcome aboard Venea30!!!!
I didn't see anyone reply back to your question about water. You are fortunate that you couldn't get the engine running if you didn't have water running though the engine. The boat either need to be in the water when it is started, or you need to connect 'drive Flush' system.

Cover the water pickups with one of these (Above) and connect a garden hose to it so water is running through the system. Otherwise you will burn out the water pump impellor.
It's also still not clear whether you are hearing the engine turn over and not start, or whether you are hearing the starter turn, or whether you are hearing just a 'click', or if you are hearing nothing when you attempt to start the engine.
