Help with engine swap please

[Morris mowing]

Hello all. I'm brand new to the forum. I have a 2017 Pro Turn 260 (992267)with the ZT740 kohler. Bought the unit with 104 hrs on it. Sitting right at 1700 hrs now. Mowing 2 weeks ago and she died. Tried starting back and had no compression. After checking the obvious places I broke the engine down to find a broke cam gear ?. Now with engine off and tore down I'm going to rebuild it, but my question is... is there anyone on here that can tell me of a higher horsepower engine that will match up fairly seamlessly? The 25 confidant just doesn't have enough juice for my 2 week yards. Any help would be greatly appreciated. Thank you.

Appears the confidant has a 1-1/8" diameter x 4.36" length Crankshaft, Tapped 7/16"-20
Small Engine Wharehouse CLICK HERE
all the shaft lengths on these are 4 9/32", 4 3/8" 4 5/16" and 4"
i guess measure yours and see...

It's right on it. 4.368

alright so it's a 4 3/8" length,
here's 2 pages of refined results to the shaft length now, http://www.smallenginewarehouse.com...Shafts"&fq=(Shaft_Size_s:"1-1/8\"Dx4-3/8\"L")

So the ECV749 3027 would be perfect but my unit is NOT fuel injected. Would it be possible to use my electric setup on that engine?

600 hours a year for 2 yards, what are they Yankee Stadium ?
A bigger motor will not make the mower go 1 foot a hour faster and 27 Hp should be well & truley enough to run a 60" deck .
What exactly are you mowing and what is your set up ?
Got a horrible feeling that the Kohler has been running on one cylinder or doing something terribly wrong if you feel it is under powered.
HAd one customer who wanted a bigger engine because his mower was "underpowered"
Turns out it was the combination of deck & blades .
HE was running high lift gators in a shallow deck with a mulching plug
Changed to low lifts & problem was solved .
And this was a Great Dane 61" deck & 18 Hp Kohler Command

Not unless you rewired the mower to accomodate the fuel injection electronics.
From What I have been led to believe anything over 30Hp has to be fuel injected to comply with pollution regulations.

I do not want more speed. That's not the issue. I mow an average of 85 to 90 yards a week. Several 14 to 15 hour days. So the hours do rack up. I live in Tennessee my 2 week yards bog the Kohler. it's a 25hp zt 740 confidant. I do run high lift scag blades. Not gators. X factor 2 deck. Gravely pro turn 260. Thank you for your reply.
