mine is running with the cav plate above water line and im just on the top hole with no jack plate and no setback.
he is nowhere near running on the cone, so i dont see how he could lose water pressure.
The bullet on his engine is completely submerged, not even a glimps of it.
I noticed he has a nosecone, and it looks like they make a realy big splash, a lot more than the normal bullet.
so whats the advantage of these cones ? im begginning to think they are just a gimic that dont realy work.
if they cause the water to go up the gearcase and away from the prop then they are obviously diverting water away from the prop .
this would mean less thrust due to less water at the prop.
If they are helping to raise the engine then they would not help with water flow due to the cone pressing down on the water. !!!!!!!!!!!
now the vid above shows a jack plate with setback,nosecone, and a hydrofoil and he still only gets 70mph on
a 13ft lightweight raceboat with a 130hp engine.
something dont sound right, how comke all these race improvements yet not much speed.
I could get that on my dory with 130hp engine let alone a racing boat.
