[Alberg30] Engine installation

[quest433 at msn.com]

Rob,

The old atomic 4s ran at about 1500 to 1600 rpms and used a 13X7 with a direct drive.  I guess your new diesel will run at about 3000 and, with the 2:1 the 13x7 is about right.  Agree?

Jim: I just got from Michigan propeller the recommendation to use a 13 x 7
3-blade with my Universal M-18. About 14 hp with a 2-1 trans (hurth 50).
Interesting.

> For flex coupling there are also the type that bolt in between your
existing flanges.  A couple examples are in:
> Defender p 171 and West p 253.  these may require shortning the shaft, but
allow you to use the flanges that came with the engine.   When I repowered
#240 I used this type coupler and am quite happy with it.  I wish my current
boat had something as simple.  On #240 I used a 13x13 three blade prop with
the Yanmar 2GM.
