And how far will the prop be from the strut . what size shaft ? I believe the rule is 1.5x shaft diameter max . I will check
Why are the engines being installed farther back ?

They can get the props on by turning the rudders sideways but I don't know about getting back off. The shafts are 1.25 "

Big D did you look at the photos of the shafts ??
I just look at photos and I can tell you the shafts are way to far from the struts . I will try and find some document ion but I do believe is around 1.5 X shaft diameter . and your way way past that .

A search on the net I came up the distance should be the same as shaft diamater in your case 1.25 one site even said 1/2 shaft diamater
I belive thats over kill .
" Distance between strut and prop hub should be no more than 50% of shaft diameter."

My tri is stored for the winter. Measured and its = shaft size. Just over 1" from the strut and my shafts are 1-1/4.
I would have them shortened, putting the prop that far out on the shaft is going to be a TON of pressure on that without support and could lead to your shaft snapping and or wobble on the prop itself.

I don't have a side view but from this photo you can see small distance from strut bushing to prop hub. I would say the OP's photo shows the shaft much too far back.

I don't have anything to do, so I'll go over and shoot some pics of the stock configuration from the side this afternoon.

OK. Here ya go. There are a few in this album to look at. Don't mind the nasty bottom paint, I don't.
Theres also an F-30 on the hard close to me, and some various shots of my favorite F-32 and the HBYC today. I also might have snuck in one of the last cruise this fall and one of Mr. Ewan on the dock.

Dave Gerrs book is excellent to document strut to prop clearance. I agree the rule of thumb is 1/2-1 shaft diameter clearance.
It really bother me that someone in the marine field would say that sliding the shaft aft 3" is OK. It's not (fro a bunch of reasons) and I would be running from this guy if he was doing any work on my boat.
Cutting the shafts is no problem ... I had to when I repowered my F-32. Any shop that deals with prop shafts can do this... i wouldn't necessarily have just any machine shop do this, it should be a shop that's familair with shaft work.
