Nanni Engines

[Meg]

Hello Forum friends

I wonder if anyone can tell me what HP a Nanni 50 engine is. I purchased Norfolk Dream earlier this year and despite hanging upside down in the engine bay only have advertised 50 as engine type and  the Nanni website is a minefield.

Just trying to get some idea of likely fuel consumption.

Many thanks

Hi Meg I would take the 50 to mean it is a 50hp engine but I am no expert on the Nanni range.

Depends weather it's from the current engine range or the previous models. I fitted a 4.195 to mine 5 years ago which is rated at 40hp.

Link didn't work to previous range.

I notice that Peachment give the HP of the N4.50 as 50 hp whereas Nanni give it as 47.5 hp !!

50 is just a marketing term. It's roughly 48hp so near enough as far as most engine manufacturer's marketing teams are concerned....

If it's in the AF / Broom 29 Sedan in the OP's avatar then I assume it's probably one of the older models rather than the N4.50. I'm not sure they're that different, really, though.

Whats 2.5hp between friends.

Based on a Kubota V2203 49hp engine

It won't be expensive to run of you keep the revs down and don't thrash it around.

 

We hired a Broom 29 with a Nanni 50 in Brittany a couple of years back and it used less than 1.5 litres per hour on a weeks hire which included some use of the heating as well.

 

The engine was well suited to that boat but it was under propped as most hire boats tend to be.

That’s a sister boat to ours (Norfolk Lady) and must surely have the same type of engine.  Not sure about the engine model, but ours was also advertised as 50hp when we bought it almost a year ago.  We haven’t actually measured it in litres per hour, but as long as the revs stay below about 1900 - 2000, it seems economical enough.

I remember seeing Norfolk Dream advertised at Jones Boatyard on the Great Ouse last year when we were looking for ours, before it appeared as SOLD on Norfolk Boat Sales website.  Being nosey, I know, but I did wonder if you’d seen it there and arranged for it to be moved to the Broads by NBS.

Good luck with her.  We’ll watch out for you when we’re out and about on the rivers.

Sounds like Norfolk Lady is also under propped if you need to be getting up to 2000rpm!!

 

The one we hired in Brittany, which looks very similar to yours with the cream stripe and rails on the coach roof was doing about 4mph at 1300rpm and about 5mph at 1500rpm.

Thank you everyone that's very helpful. What with lockdown not been any further than Salhouse yet but  she has a Garmin measuring device and seems to perform like the Brittany one. I will look out for Norfolk Lady and give you a shout. I bought her from Norfolk Boat Sales as part exchange. She is a lovely boat. Again good info thanks

Not sure.  We usually cruise at about 1600(ish), which equates to about 5mph, but being based on the Southern Broads, sometimes we have to push the revs a bit, depending on the tides.  On the other hand, when cruising with a falling tide, we can achieve the same speed at lower revs.  It does rev to 2600, but I do have some mechanical sympathy, so have never cruised at that.

There were at least three builders of those 'Broom' sedans for LeBoat, based on the ones I've seen.

Broom themselves did some, Darragh did some (the fitout of which is visibly different, and a bit odd like most of their fitouts) and I've seen some with a Shannon Yachtfitters build plaque.

The Shannon ones look similar to a Broom fitout but there are some visible differences. I suspect they may have been at least partially fitted out by Shannon based on being sent a kit by Broom as some of the joinery is very similar to what Broom do - Either that or they were subcontracted.

Ours is a Darragh, but frankly I can’t see much difference between it and the Brooms.  In fact, the guy who conducted our survey actually commented on the similarity of the interior fit out.

The similarity is because they were all built for the same customer to go into the same hirefleet. But actually, yeah that does like quite conventional for a Darragh fitout! On larger boats they have a trademark sunken galley to the side of the saloon, allowing a larger side cabin forward where Aquafibre / Broom designs typically have the galley.

It probably takes a boat geek like me to spot the real detail differences. The door handles and air vents in the hull immediately tell me when a 29 isn't a Broom build and then I start spotting other stuff such as handrail positioning.

Nice boats, though. I'd have one!
