im running 1-1/4 shaft behind a cummins 5.9 in my express 27 with 19" prop.
1-3/4 shaft is plenty for your application, if anything, since your new motors are longer you might have to shorten your shaft. eric ----- Original Message ----- From: [email protected]<mailto:[email protected]> To: [email protected]<mailto:[email protected]> Sent: Sunday, October 18, 2009 5:02 PM Subject: [UnifliteWorld] Re: Uniflite Shaft Material A friend of mine converted his 38 SS to Cat engines several years ago and he retained his stock shafts. His cats put out 426 hp and could run full out in excess of 34 kts. That peticular 38 was in portland Or, named Minaki. That boat burnt to the waterline and sunk 2 yeras ago but the engines and running gear was salvaged and now are in another vessel. There are several stainless alloys that can be used such as the 304 you commented about. 316 could also be used along with 17-4PH or Carpenter Technologies Aeromet 100 to name a few. Hope this is helpful.
