Duromax 16hp electric start
10 years ago
So far so good! The engine fires right up with with either the electric or pull start. It's quieter than the 11 hp motor that's on my snowblower. MaxTools had it to me within 4 days. We'll mount it to a mud motor kit for my son's duckboat and plan to work it hard this fall.

GREAT PERFORMER
11 years ago
I purchased one of these to replace the FE290 Kawasiki in my 1996 Club Car two years ago. This engine bolted in to the existing engine mount with no modifiction and has been trouble free since the install, always starts right off in cold weather and has great torque. I would recomend to anyone as a replacement engine for the Club Car engine.

DuroMax 16 Hp., 1'' Shaft, Recoil/Electric Start Engine
12 years ago
Used this engine to replace an 18HP engine that was on a large wood splintter that had worn out after 30 years of use. I was impressed with how well this engine handles the load. It looks like a Honda engine. How don't know how you could do any better for the price. Max Tools did a super job shipping it out.

Seems well-made
12 years ago
This engine appears to be well-made, sturdy. Just got it installed and running, so not much experience with durability, but the finish and construction appears to be much better than typical Chinese products (could it be the same mfg. equipment used by Honda?). Hope the inside is as well-made as the outside. If so, I will be very satisfied.

great for what I needed
13 years ago
I upgraded an old Sears Craftman shredder that is about 25 years old. The motor was shot and I couldn't find another motor with a 1 inch shaft to fit. It was a 5 hp. The one from you is 16 hp but much quieter and starts easier. I had to modify a few things because it was made 25 years ago and thing change. I'm very happy to have found you. I order from you again and tell others. Thank You

Good buy for clone engine

I got this for a go kart. It's a LOT bigger than the one that came out of it so I had to work with it some. Take the gas tank off and mount it on the frame. Things like that. Put it all together and it fired right up and has been running flawlessly for the past weeks.
