It's the shape of the leg on the Tohatsus that causes the splash back most other engine makers have different leg profiles and don't have problems
, there is a flat on the leg casting thats normally above the waterline that causes the splash everything else is pointy,
Mine only splashes back at displacement speed when up on the plane the boat lifts up so the flow of water then clears the flat part and it reduces the spray
, I fill in the flat in with a shaped block of wood and hold it in position with tie wraps.
Saw on a post a few weeks back about using foam pipe lagging slid on the top edge of the transom that helped someone .
I did make some spray deflectors that tie wrapped on to the leg out of thick sheet rubber something like a set of Doel fins .
