[Alberg30] Diesel replacement

[Scott Maury]

I had my at4 rebuilt 3 years ago and it purrs! I have concidered installing
a reduction gear by moving the engine forward and installing a larger piched
wheel. the draw back is going to be the vibration! any thoughts?  that would
be a 2500 rpm with a 1250 prop rpm  say 13x13 pitch?

This topic seems to have triggered a lot of interest.  Personally, I
plan to replace my Atomic 4 with a "new" Atomic 4.  For local usage, I
don't think a diesel is worth the cost and aggravation.  If I were
heading off long-distance, I might change my mind (as did Matt Blaine).
  More likely, I'd go ahead and try it before committing to an engine
replacement.  After all, I might not find such cruising to my liking.
Or I might find it not a problem.  Certainly people have cruised the
waterway and even down to the Exumas in a gas-powered Alberg 30.

For another opinion, see Jim Davis' article on putting a Yanmar in an
older Alberg 30.  He's just sent me a copy and I posted it at

  While it's about the older boats, there's plenty to be learned for
those with newer boats, too.
