So removing the restrictor plate results in more fuel burned at same rpm
use didn't change, just had a neutral shift for my kids
with the 3.3.
I'm skeptical. I would think that the restrictor plate was there to limit maximum fuel mix flow, thus slower top rpm
(which I believe the specs show), thus lower hp.
As far as the part numbers being the same, are you sure that this is true across all brand labels? Not that I conducted a complete study, but the only 3.3 I recall
seeing at the time was the Mercury
. With all other brands it was 3.5. Perhaps Mercury (and Mariner) for some reason spec'ed something different from Tohatsu?
FWIW, this weekend I will determine the gear
ratio that my 3.3 has.
