Boat needed - to strap 4 x 300hp on
Discussion
Is that testing with all four engines on the boat at once? Florida would be the place to find something suitable if that is the case.
Something like this should do if you only want to test one or two engines at a time:
2016 Specter 32 Raceboat
You need to find out if the primary requirement is to demonstrate the engines to customers, in which case appearance and performance may be paramount, or if it is for trials purposes, so having plenty of room for instrumentation and easy access to the engines when in use is more important.

But 'Gonna need a bigger boat'... I was thinking 'cigarette boat' territory - although not that prevalent in Lowestoft area where wanted !
OXE 300’s? Very interesting development. Although being based on BMW TDI engines, they don’t have the best rep for longevity in automotive duty, let alone marine duty. So they’ve got some work to do there.
Quad outboards is pretty much exclusively US made center console territory, with a few sport cruisers going that way of late. Not sure you’ll find many UK/Euro available platforms off the shelf that’ll work?

No.(and I can also talk about those and trials tribulations ongoing with the very same, but not publicly for now. Engine so far fine. rest of package is providing headaches)
An engine manufacturer at Shoreham Airport perhaps?
Boatwise, talking to the US Coastguard or Drugs Enforcement Agency to see what they have to dispose of might be the way to go.
A quick look at outboard-powered cigarette boats suggests they are upwards of $200,000 for a used one, and I'm not sure I would want to hang 1200hp of engines on the back of the cheapest available.

Your problem using all 4 at once would be that any normal boat designed to take an outboard will not have a sufficiently wide or strong enough transom to take them.
Most "fast" boats are already fitted with something approaching the maximum! And there's also the stability issues that all the excess weight and power hanging off the back will cause, while the more substantial powerboats that could take that weight and power will not have transoms designed to take outboards.
Though I suppose you could fit some sort of rail or something (but no one hiring out their boat would allow that!)
If it's not to evaluate how well they actually propel a boat, but just to run them at sea for evaluation, then how about a boat thats rather large and slow (as dull as that would be).
Some sort of workboat/tender/Multicat or even fishing boat might do the job though, if you had mounts made up and welded on to take a substantial plate to mount the engines.
No idea how well it would propel something like that though, but it would be funny to watch a rusty old tub pottering about with a ludicrous amount of power strapped on!
Surely running two twin-engined RIBs or whatever would be a more sensible and realistic option!

‘We’ have a not dissimilar set up currently with a pair of OXE but the request was from a new entrant to the market looking for some vessel for the tri or quad installation
I’ve driven the twin engine cheetah they are using as a test boat. Impressive
The engines weigh in about 500kg each - so one hell of a transom, but with the duo prop and torque these monsters push out - it would put some loads in the boat when pushing the sticks to WOT
Thanks all- nothing ‘floating ariund’ suitable on the PH radar :radar:

Bit late to market though?? Cox have been there a few years now.
There is space for three in the market- also pros and cons to all three.We couldn’t choose Cox because of their gearbox / clutch arrangement (dog clutch not wet clutch) and the torque these units make means they ability to go through the gearbox a fragile process.
Cox have a great mcl engine - and for the leisure industry imho not for work. Yet the COX have a whiff of dirse about them we don’t have with the OXE
Saying that - we have been having nothing but trouble with our OXEs
Hence the support of this third entrant- we have been watching and assisting with real world requirements and testing for some time now.
Anyway - a boat with 1,200 nailed in the back, would be fun.
A wander around boat ads suggests that quad outboard boats are a relatively recent thing and as such prices are still in the £1M+ range.
What is the feasibility of taking a boat designed for that sort of power in inboard form, but available at a considerably lower price, then spending some of the price difference converting it to have a stern capable of supporting 4x300hp outboards?
Maybe using something like this as a starting point?
Wellcraft Excalibur Eagle 42

What you need is a Dai Fei (Hong Kong smuggling boat from the 90s). 80 knots on the plane, even when loaded with a big Merc or BMW.
