Excellent easy install
I purchased this engine to replace the Briggs INTEK 540CC 18.5 HP in my Husquvana riding mower. Almost everything was plug and play. The only thing that i had to change was to remove the muffler on the new engine and install the old muffler on the new engine so the hood would shut. Install took about an hour. It fells good to buy an American made product for a change. ... show more

Good engine
Engine came in new condition and was delivered very quickly. I put this engine on a walk behind mower that was not setup for electric start. I got everything wired and hit the start button and it started right up. It has plenty of power for my 4 ft walk behind mower. The engine that was replaced was a Kawasaki FB460V which was 12.5 horsepower. Besides the wiring it was a direct replacement. Bolt holes line up and the throttle cable is almost in the exact spot. Very pleased with this engine, gave my old mower a new feel. ... show more

Totally happy -- so far.
Good deal for the money. Easy to install. Direct replacment for Kohler Courage. I've got about 10 hours on it, starts every time, runs good. Will it last? Ask me in 2 years.

Straight Forward Swap even for a 73 year old
I have been using this motor for several months with no issues. The swap was straight forward but, since I used all hand tools it took a little muscle power. Everything hooked up easily to my Craftman YTS3000 mower. I did need to modify the hood to accommodate the side muffler. Sine I am 73 years old and was successful in swapping engines out, I feel this can be performed by anyone with a little mechanical knowledge. I did not like that it did not come with the proper manual. ... show more

the need to tap for bolts. or shopping for some .
item was delivered 2 days early so was nice. All 4 mounting holes are not threaded so you will need to tap them or buy bolts and nuts to install. I used old bolts after tapping at 3/8 .Engine install was very straight forward making it a simple swap, engine has a preinstalled muffler which i left but i can still decide at some time to use factory one still in good shape. once all connections were done oiled it gassed it she started right up . bad engine was 21hp, but this one has plenty of power to run and get the job done. P.S no manual or instructions ... show more
