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.
Good luck.

I've read thru past posts, and searched the web. The world seems divided
into
two camps
"trim tabs are a better choice"
"whale tails/foils are cheaper and do more for hole shot"
After reading, it seems there's two types of cavetation plate 'add ons' --
foils
that hydrodynamically lift the stern, and "whale tail" types that use prop
wash.
My boat has trim tabs, but am looking for better hole shot, I've played
around
with props already. before I make holes in my cavetation plate I wanted
to know
if one or the other types of tails are worthwhile and if anyone can sum up
pros/cons between the two.
Lastly - will they really help more than the tabs did for hole shot? The
boat
is a 92 22' cuddy cabin runabout with a single 350ci engine.
