1.) The ventilation plate on my 9.9hp outboard does not have mounting holes. Do I need to drill them or is their non presence indicative that mounting a hydrofoil plate here is a nonstarter?
2.) If later I decide to remove the plate, do I leave the holes empty or do I use a blank?
This is the one I'm working with
Whale Tail XL® Aluminum Hydrofoil Stabilizer
I've gone through the forums and the message I'm getting is that for a small boat like mine (10ft Achilles SIB) with a small motor (9.9Hp Evinrude) these aren't a terrible option, though their benefits seem to taper off the bigger ones boat gets.
(I realize this could also go under motors, am a little unclear of protocol here. Apologies if the SIB section is the wrong location, but it's for my SIB.)
