I would like to replace the engine in my older LazerZ Hp but Im having problems finding a replacement Kawasaki engine. It has an FH580V engine, and every site I visit says its out of stock. I would entertain a Kohler if I new exactly which engine would work with minimal modifications. The shaft size is 1" and 3 5/32.

Thanks!

Check out my post on Kawa builds - and ask the sales team.

Trust that helps some.

I am doing Honda, likely a rebuild - my way.
I am not saying do not buy Kawa, I am saying know what you buy.

With the trend being one that clings to a price point any engine
can be modded to set a new lower standard for a chainstore
market. It's how this whole debate around "residential" and
"commercial" got airtime. My view the difference is a marketing
thing aimed at sucking extra bucks from small business, essentially
the selfemployed unemployed. "Commercial" buyers are being
duped, IMO.

I digress....

If anyone is interested, I just upgraded the engine on a 60" 1997 Lazer Z to 25HP Kohler. New motor drive Shaft is 1 and 1/8th inch and requires a new clutch and new clutch spacer. A little trimming required on the hydraulic drive end to accommodate the oil cooler, but other than changing the oil drain it was a straight forward engine swap. If you have an older 22HP engine, the new clutch is slightly larger and requires a longer deck drive belt, although it is possible to make the existing drive belt fit.

Easiest thing to do is to go to some where like Small Engine Warehouse , Small Engine Services , Repower etc.
These peple specialise in supplying replacement engines for old mowers.

Mower engines are fairly well standardised and come in 3 basic sizes ( metric ignored ) from push mower to 10' fairway mowers.
Nearly all engines from 8 Hp to 28 Hp have a 1" x 3 & 5/32 crank then they go up to 1& 1/8 Diameter.

So the criteria is how much fiddleing with electrial connections & throttle controls you are happy doing.
Usually the same brand engine will drop strait in & plug right up but you can replace your Kwaka with a B & S , Honda , Kohler , Tecumseh or any cheap Chineese copy you like just so long as it has a governor

Thanks bert! I just rebuilt the engine in mine for now and Im trying to get it running right. Im trying to find an aftermarket muffler for it now. That seems to be a challenge.

You most likely won't
In most cases the muffler is made specifically for the application so they end up being unique to that particular combination of engine & mower.
If you still have the old one, cut out the exhaust pipe ( note out not off ) then find a muffler that fits in the space & weld the old pipe onto it.
I have seen a lot of mowers fitted with a short universal motorcycle muffler for just this reason.
Might look real cool with an upright stack & top hat.
