[C320-list] Transmission ratio

[belairlk at aim.com]

Are you sure Maverick, #1007, has 2.2:1 gear ratio?  Aqua5, #1070, has same 3YM30 engine with 2.62:1 gear ratio (verified on trannie plate).
 
Planning to change 3-blade fixed to folding Gori 2-blade 16-1/2 x 13.

While the list is on the folding/feathering kick, might as well add my 2
cents worth...

Maverick (#1007) has the newer 3YM30 engine, and a fixed 3-blade 15x9 prop.
Transmission reduction ratio is 2.2 Fwd, 3.06 Rev

I have a Max-Prop 15x10 3-blade prop (as recommended by PYI) on order to be
installed at Spring haul-out.
We have 680 engine hours in 18 months, 4115 nm. on the log.

I am planning on purchasing a folding or feathering prop at sail-Chicago.
Great Scot is a 2002 c320 with the Yanmar 3GM30F engine. Serial # E29213.
Where do I find the transmission ratio? Is it on a plate on the trans. I am
going to my boat tomorrow to get that information. Great Scot is 100 miles
from here. Any help would be appreciated in locating that information. At
the present time I have the standard 3 blade fixed prop.

Larry
Great Scot #924
