[Alberg30] A-4 and Propeller

[Dave Terrell]

I looked at this last summer and I believe the A4 manual says idle
should be around 600 RPM.

The 13x7 prop is the standard prop that came with the boat. 1000 RPM
sounds 
a little high for idle, I think you could get that down to 600~800 RPM.
Hull 
speed should be achieved using this prop on a proper running A4 in and
A30 
at around 1400 RPM.

Hello Fellow Albergers
I am new on this your public-list. I have not sailed in the past 5
years 
having had my boat out of the water. But having sailed all my life, 
returning to the sea  is not difficult. My brother and my self own each
an 
Alberg 30. I am asking this question on behalf of my brother.
Question::
His boat has an A-4 and a propeller 2 Blade 13 dia  x 7R pitch. He
claims 
that his boat is to fast on docking  3.9 knots at 1000 rpm and does not

reach cruising  / hull speed  at normal 80% engine rpm. He thinks that
the 
previous owner changed the prop and this one is not the right one.
Can some of you A-4 fellows out there just tell me what
size/pitch/blade 
propellers are your machines running with.
Many Thanks in advance.
Villo Marmei

PS: I have some sort of pass word for our public-list.....am I supposed
to 
show the  pass word each time I send an e-mail to the site or is it the
same 
as with regular e-mail????
