I Have a yahama wave Venture that starts when is out of the water, and works perfect, but once it goes into the water does not run.

The other day I went to the lake and I forgot to put the drain plugs in, a lot of water came inside the engine compartment.

I Dont know where to start looking, any ideas would be appreciated.

Won't run in water.

You almost certainly have a blown head gasket. It doesn't run when in water
because the cylinders are filling with water and this also explains the water in the hull.
