    Im buying a used 48" eXmark lazer and everything is pretty good on it except for the engine, the engine is completly blown, im getting it at a very low price so its no biggy. I just needed to know all engines that would fit on it and which one you guys would prefer! Thank you guys!

    I've replaced an engine before and with pneumatic and specialty tools that took an afternoon on a machine I've had for 4-5 years, then it took a LOT of tweaking and getting everything just right, almost two years after that day the mower finally runs the way I like it... Which, it doesn't break down every 5-8 cuts anymore.

    I will admit I'm a fanatic and I like mine to run like racing engines, but an old machine simply doesn't always take too kindly to new-found power, a lot of other things broke as a result and it was minor in terms of money but parts and labor you're still looking at a minimum of a thousand dollars and you can not just take any engine that is roughly the same horsepower as that more than likely will not work.

    As a general rule engines for these mowers cost anywhere from $7-8-900 and it keeps going all the way to $1500 not counting the labor, all depends on the specifications and the first thing anyone will need is the model number off the blown engine as that would help cross-referencing the beast.

    To soothe what could be some nerves that Intek MIGHT work, but still need the model number.

    okay well this mower has less then 1000 hours on it and im most likely getting it for around free to $300 dollars, so if i have to pay 1500 for a engine im not too worried about it, and i would not have to work on it at all. My grandfather, who has been working on dirtbikes and tractors since he was 20 will be putting this all together for me so free labor for me. But i hear briggs arent the best engines to stick on a mower. Ill probably end up going with a 21hp or 19hp KAI because i think it came with a 19hp KAI originally.

    Yeah $300 is fine, for that kind of situation.
    I didn't mean to come off like that but you said ASAP and I'm like DON'T make a mistake! :p
    Also the labor was a big thing, you have that covered so with 500-1,000 hours if you're out a little over a grand that's cool.

    The biggest thing is the current engine's specs, stuff like shaft size and ES / recoil,
    obviously it's vertical shaft :p

    yeah ive been trying to talk to him about that. All he keeps telling is look around for 19hp Kawi engines. Im going to write down the serial numbers tomorrow. And I think ill be paying $450 for it, which still is not that bad.

    All right...
    Anyhow, first off yes you can put a briggs on it, so long the shaft size and a few other specs match.

    But, to find what it needs, try this page:

    See if you can find that lazer and then see if you can nail the engine model number, more than likely it will be a Kohler or Kawasaki but that's fine, just need the model number off the engine.

    I just put a short block in an '01 60" Z we have. The short block cost $900 and the heads cost another $300 plus valves, springs, seals and the like. Brand new motor was $1800. I did all the labor.

    I replaced it with the same Kohler 25hp that was in it. Like everybody else said, just make sure shaft sizes are the same.
