box came soaked in oil no dammage to box or engine very easy to install works great thank you
Reviewed in the United States on June 6, 2025 by archie zito
This engine was mishandled in shipment, the carton was damaged, all of the oil was drained and all over the box, evidently it had turned upside down during shipment. The plastic screen bolted to the flywheel was damage but seemed to have no effect on the engine. None of this was evident until I opened the container. I installed this engine (44S977-0033-G1 25HP) on an old 48" Scag replacing a very tired 20hp Kohler. The Briggs engine had the same mounting bolt pattern as the Kohler. The crank shaft dimensions were close enough for my pulleys and clutch. This Briggs engine come with electric start but has no solenoid also no muffler, I ordered a Swisher muffler #14391, came with gaskets (170 bucks), fit was good. This was not my first engine of choice but comparing cost, availability, it will do the job. It made this tired old machine like new and it is a beast. Very satisfied with the overall performance.

Quick tips. This does not use a choke cable so just dont even try to connect one. This does not come with a starter solenoid, just pick up a 2 prong starter solenoid at any auto parts store. Does not come with oil in it. Many reviews say they had to tap the motor mount holes, dont waste your time with this, just get a bolt and locknut. Easy install and mows a lot more powerful than the Kawasaki 20hp i had on it!

Easy install only thing different is now my throttle control works reverse of what it was before. No fault of the sender put maybe a BIG "THIS SIDE UP" on the box and all the oil wouldn't leak out and all over the motor. Also by being turned upside down the oil dip stick came out and was bent, I straightened it, no biggie there but by the cap being off Styrofoam got in to the oil fill tube, I flushed engine with a quart of oil and a few pieces came out. I'll do a oil change at 1 hour and again at the 5 hour break in period. If I wasn't in need of the motor I'd of sent it back. Also and again no fault of the sender but this order kept having delivery extended a day, 3 times! I finally went and picked it up myself

When this motor arrived the box was damaged and oil was all inside box. I was desperately needing this motor and the engine appeared fine so I went ahead with the install. Everything went fine and put oil in and checked to ensure had plenty of oil and fired it off. White smoke went everywhere and filled the whole garage with white smoke. I thought maybe it was just the first run. The smoke has gotten better but still smell a burnt oil smell as I mow. Tried to return or replace or some kind of support and can’t get anything. Would not recommend this motor to anyone

runs good but a few things were annoying. No oil pressure switch was included, just a plug. So that means no oil pressure switch wiring. Throttle was opposite of my old engine, haven't fixed that yet so not sure what the issue there. Doesn't have the linkage for the choke like the old engine. Otherwise starts and runs well.
