Default Cavitation plates (foils vs. whale tail) along with tabs.

That would be a stern drive unit then, eh?

You should not need any add on devices with a 350 with a boat that small.
Again, assume it is at least a 260 HP engine, eh? HP is so much more useful
than CID when looking at hole shot.

I just switched to a four blade prop to improve hole shot, acceleration, and
to maintain plane at lower RPM with my outboard engine. I assume I'll lose
some top speed but that is OK as long as I can turn the right RPM at WOT .

As your boat has tabs I seriously doubt you will much improve hole shot by
adding a hydrofoil device to the cavitation plate.

If your engine is producing sufficient HP, if your boat is not overloaded,
if your drive is properly proped, and if you are a good boat operator you
should have good, if not oustanding, hole shot.

If you do not have good hole shot and you are a competent operator with an
engine in good tune, I would revisit the prop selection issue.


Couldn't have said it better.
