The prop shaft was pretty husky for a 35 hp engine and a 50 inch wooden prop. john h mkIII Titus, Alabama A long time ago these shafts were plagued with breakage. Supposedly there was a fix.

In my ultra stars documents is a hand written letter by homer himself talking about the prop shaft failures. He stated there was a fix and most we're upgraded but I'm looking for some details here to decide whether I need to address mine. It sure looks beefy tho... A shaft failure of a pusher would be bad indeed. He also states that eventually the cuyuna cranks will break from belt tension. Looking for some info on this as well. -------- 1984 kolb ultrstar Former 1997 kolb firestat Read this topic online here: http://forums.matronics.com/viewtopic.php?p=432280#432280 ________________________________ Message 5 _____________________________________ Time: 08:27:38 PM PST US From: "John Hauck" Subject: RE: Kolb-List: Re: ultrastar cuyuna prop shaft breakage Do you know when the US kit was purchased? I bought mine Feb 1984, one of the first US kits to be shipped with factory welded fuselage and components. Earlier versions were shipped as material kits with builder required welding. Don't know when the ULII02 replaced the 430, but may have been a factor in possible crank shaft failures. john h mkIII Titus, Alabama I agree but....
