Bucket to run engine in

[Croolis]

Short shaft 4 stroke 9.9hp that I shall be putting on a sack truck with bucket o' water underneath.

The sack truck is the ~£60 blue macallister one oyou get from Screwfix that I've seen folks use. I've used it to trolley motor around already so I know it can take it OK. I shall take steps to ensure stability when engine is running. I've made a wooden stand for the motor that it lives on but because of the amount of vibration etc. while it runs I'd rather trust a welded metal frame than my wooden knock-up.

I've only ever put engine in a wheelie bin of water before and run it, but that made the wheelie bin all funky, and I'd have to lift it quite high so I'm not doing that again. So I'd just like some advice on size. It's quite hard to tell the dimension of bucket from pics and vids of people doing it, and sometimes I think they look like they're sailing very close to the wind they are so small.

How much clearance do you need around the prop and shaft?

tl;dr : Is this tub the right size to run a 9.9hp short shaft 4 stroke in:

Cheers for replies

The water container should allow a depth similar to normal immersion depth (a little less is OK). You probably shouldn't be running in gear except momentarily to test gear selection, so clearance around the prop isn't critical. I doubt that the box shown is deep enough, maybe consider cutting down a bin?

Sorry for your recent loss.

Thank you .

or this - allegedly the same but stronger

Both ~50cm tall, which must be enough. I'll go Asda this pm and compare, see if the extra money looks worthwhile

In all my engine test run images you will see the famous yellow bucket. After several years it had just been replaced with an identical one from Aldi... £3.99.

Another long term aficionado of the ‘big yellow bucket’ here, although have upgraded over the years to red, blue, magenta and currently orange!

Just deep enough for most portable motors up to 20hp but have found you need to get the skeg nearly on the bottom of said bucket. Worth remembering impellers are not self priming and need the water level above them to start pumping. Typically 2 to 3 inches above the AV plate seems to work well. Once pumping the water level can drop slightly as long as it still covers the intake grills just below the AV plate.

Normal depth of a builders bucket was too shallow for my Suzuki 20hp so cut down a barrel to fit, but I read that it’s one of the worst for it so you might be fine.

I did try a deep but quite narrow Aldi household indoor bin, but would urge caution, because when I blipped the OB into gear the bucket moved and the prop made short work of the bucket……much to the annoyance of teenage son who was standing next to it who appears allergic to water ��

[chipko]

If it pumps water it’s deep enough, if not it’s too shallow.

Why would you ever think running in gear was a good idea in a bucket! Even a small portable needs at least a wheelie bin to run/test in gear….and still be prepared to get wet.

A senior and not very logical moment I must agree…..but it did turn out quite amusing in the end….for me anyway….if not for said son lol

another for the big yellow bucket.

Back in the day our Suzi 20 pumping like a trooper in the hallowed yellow bucket.

Fine bucket but an even finer motor…the first efi 20hp and arguably still the best.

Yip I remember seeing them running fine in several pics and videos in shallower buckets etc……..but mine never did pee without being deeper from new, nor with muffs either for some reason.

Never tried again since, but did read somewhere more recently that others found the same. Great OB when running well and out on the water regardless.

Just back from a few days over on the west coast and never missed a beat in some very testing conditions

I went in the middle of Lidl and there it was, the big yellow bucket, just like the ones above. But I got mine in grey because I'm not a tart .

Buckets at dawn.

[Fenlander]

Nothing to do with being a tart just yellow is easier to find in the garage.... unless of course you buy too many other yellow things.
