Those engines are built with having a constant "fresh" water supply, as in, not re-using your water supply but having fresh cool water constantly available all the time. Others that know more than I do may say go with it, but that would be my concern.
You can crank a boat motor in a barrel of water and it is ok for a short run, but over a long peried of time, I would be concerned that the water would heat up and not properly cool the engine.

It would be set-up with a radiator and an electric fan. I don`t think that over-heating would be an issue.With the compactness of the unit , you could overisize the radiator and still have a smaller footprint than a standard , comparable HP engine.

Will they work with a closed loop cooling system? Most outboard motors just dump the water back into the lake, with closed loop you are recirculating the water. Will the back pressure of this recirculation cause the water pump to fail? Just a thought.

many of them dump the excess water out into the exhaust port. This is used to do more cooling as well as muffle some of the noise. most are also 2 cycle using oil gas mix. or 2 reservoirs then mix inside the engine. This is probably the biggest reason for compact size to power. same as weedeater & chainsaw engines that you can get 2 or 4 HP out of and still weigh less than you would think..

as far as the cooling issue, i would think that maybe with some sort of vented reservoir, like an overflow tank, you could probably solve any sort of recirculation or pressue issue.
my other thought on this would be.... what would the intended use be? these types of engines are generally of the type to make power at high revolutions. most agricultural use machinery is more of the slow but steady theme, hence the popularity of the diesel engine.
years back my uncle made a low budget version of a cushman out of an old 3 wheel harley golf cart. had a light gage steel dump body with an electric/hydraulic dump. the dump worked ok, but the motivation system was the issue. the first powerplant was an ancient ski-doo free air snowmobile engine. this didn't work too well - too erratic for putting around. the second attempt was a honda atc engine. this was a little better, but proved to be too slow with the atc transmission and golf cart rear end. in the end, the only thing that either of these excelled in was making a lot of noise.
