[Public-List] Replacement engine

[Mike Lehman]

Tom,

What engine are you trying to replace, Atomic 4 or Gary Marine? And you you 
want a replacement for the engine that is there or do you want to switch to 
a diesel? The engine you choose will determine the prop size and pitch. The 
max diameter for an Alberg 30 is 13". For example, when I switched to diesel 
from my Atomic 4, I changed the prop from the original 13 x 7 2-blade to a 
12 x 12 3-blade. With a 12" prop there is less prop wash against the hull so 
it is quieter and doesn't cavitate as easily. I let the prop guys at 
Michigan wheel do the calculations, based on horse power and most 
importantly the power curve on the engine at normal cruising speed.

For new replacement engines you may want to check out Beta Marine.

I'm looking for a replacement engine for an Alberg 30.  Interested in both
advice on engine/prop selection (need a little more power vs underpowered)
and any info on used engines around the Pacific Northwest (anything so long
as running).
