Shaft lengths

[Tom]

As alot of you know I own a 36 Timmy boat (hat). Broke a shaft this past Fri and she's on the hard. Located a used 1 3/4" Aquamet 22 shaft. It has 108 hours on it before the 38 Blackfin it came from was repowerd and went to 2" shafts. My other is also an Aquamet 22 but will be 1.5" shorter than the used one I am considering. Will be there be a problem in either performance or mechanically by using a slightly different shaft length, all else being equal? My prop guy says no, Slane Marine says no, yellowbeard the mechanic at Land and Sea diesel says no. What say the faithful?-Tom

Senor Hyena, el longa shaft mucho bueno no mas. El distanco betweeno el struto and salanda de prop no exceedo uno shafto diametero. Conprende?

Will work fine til it breaks. Cut it, machine shop the "U" keyway and use it. I know it's summer and time is a wasting, but do it right, or at least plan on doing it right later.

Yo comprendo jefe.

I thought as much but couldn't get any "experts" to agree. They are maching right now and after the new props this afternoon, and some wax in the morning to the topside, we'll be under way.

Yepper Tim. Me no comprende Espaniol but Englais petite. Mucho "Cracker Talk"
Just make sure you get it spooned and cut and the coupling faced and fit by a shop that has a good reputation for doing shafts. Most shops can not do shafts well. So If you have to send it away 100 miles to get it done right do it. My one before last 1 1/2" only lasted me 11 months. Never will I have a friend do it because he was good at something else in marine. Shafts are their own animal and must be done by a good shaft shop.

The keyway must have radiused edges or stress cracking can occur.
