The weather is so horrible I've just hunkered down though. Bow slap here is something chronic. Shop pert of the pub so probably closed too. Real struggle mooring here but plus side being blown off bank is a comfortable mooring. Mind you, after a few double gins Mrs Nog will be sleeping soundly particularly if I'm paying Hope you get a good night's sleep though and look forward to your further adventures tomorrow 2 1 Quote Link to comment Share on other sites More sharing options...

The key that we received through the post doesn't work. It won't turn. Broom have charged the syndicate for those!! 😡. Time to have a word with Dee, Helen, methinks. 1 Quote Link to comment Share on other sites More sharing options...

I will! The guy who was on board last week had some difficulty initially too but did get his key to work, and he's emailed some tips, so we'll have another try tomorrow.

The heat exchanger cap has a small plastic pipe going to a plastic water bottle sitting beside the engine in the bilge. That cap on the heat exchanger is not a pressure cap, it is where you fill the engine with coolant when necessary. This pipe should be going to an expansion chamber, which has a pressure cap and should be fitted on the bulkhead at a level higher than the engine. Without this, the cooling system will not be pressurised as it should be and so the thermostat will not be working properly. This chamber is in opaque plastic so that you can see the coolant level in it and is exactly the same as what you probably have in your car. I am sure Peachments will have this part in stock and it is rather important to have it fitted. 1 1 Quote Link to comment Share on other sites More sharing options...
YnysMon Posted February 14, 2022 Author Share Posted February 14, 2022 Thanks. Very much Vaughan. I will pass this information on to our management agency and will ask them to query it with Brooms. 1 Quote Link to comment Share on other sites More sharing options...

YnysMon Posted February 14, 2022 Author Share Posted February 14, 2022 Now moored up at Irstead. Initially we went to Neatishead, but when we got there the water was off (should have got water at Acle or Ludham Bridge), so we went to Sutton Staithe where we filled up. Sutton was really muddy though, what with that and the traffic noise we though we'd find another mooring. It was before midday anyway, so plenty of time. If Irstead had been full we'd have tried Ranworth. I won't add a photo as the signal here is really slow. 4 Quote Link to comment Share on other sites More sharing options...

We had been expecting to see Humber Bridge at Acle, as we set off not long after seven ourselves, but you were long gone. 1 Quote Link to comment Share on other sites More sharing options...

Sorry Helen to invade your holiday tale, we were out at the weekend and the wind was certainly giving us problems. Quote Link to comment Share on other sites More sharing options...
CambridgeCabby Posted February 14, 2022 Share Posted February 14, 2022 You can fill up with water at Ranworth and Womack (very slow here though) and Gayes staithe I believe Paddy’s lane is now back on too Quote Link to comment Share on other sites More sharing options...
NeilB Posted February 14, 2022 Share Posted February 14, 2022 I think these are Nanni's own design of pressure cap and the use of an expansion tank is optional. The outlet is just in a different position than the more traditional version. Quote Link to comment Share on other sites More sharing options...
Smoggy Posted February 14, 2022 Share Posted February 14, 2022 I would guess there is an option of setups depending on wether you use a blank cap or pressure cap on the heat exchanger, it is effectively a header tank after all as long as the water level stays above the top hose level, the thermostat should look after the running temp. Does that turbo ever get to spool up on river speeds or does it get a proper leg stretch from time to time? Under used turbos tend to make for a smokey engine as they never keep the oil sealed very well without a bit of pressure in the compressor side, my volvos give a good puff of blue on a regular basis on the rivers but run clean once opened up.

As far as I’m aware, there’s no turbo on the Nanni 4.50, which is what’s been fitted to Moonlight Shadow. Quote Link to comment Share on other sites More sharing options...

BroadAmbition Posted February 15, 2022 Share Posted February 15, 2022 Brundall Navy - By not having a pressurised header tank or having a pressurised expansion tank as in your case, primarily this means that the engine coolant will boil at normal boiling point. Pressuring the system by either of the above means raises the boiling point of the engine coolant. I would have thought you should really have a pressurised system Having a non-pressurised system - I doubt this would lower your engine operating temperature, I would have normally thought the opposite would be the case and it would be getting too hot to quickly. Maybe the thermostat is sticking open or not enough load on the engine via too small prop / pitch on prop ? Griff Quote Link to comment Share on other sites More sharing options...
grendel Posted February 15, 2022 Share Posted February 15, 2022 it looks to me that both have a similar cap, it has a vent pipe, so i would assume that it is a pressure cap, its just that one is vented to the bilge, and the other vented to a container. as stated earlier, the cold water header tank is both a heat exchanger and a header tank combined, so no necessity for an external reservoir (and 2 less connections to fail.

Smoggy Posted February 15, 2022 Share Posted February 15, 2022 Pressurisation won't change the running temperature, it does prevent gasses in the water boiling out causing bubbles around hotspots like exhaust ports which can soon cause a cracked head, an under stressed broads boat engine wouldn't come to much harm. Some caps have two way valves so can pressurise and blow some excess out if needed and suck some back in when cooled. Quote Link to comment Share on other sites More sharing options...

They had put down a load of newish chippings at the Staithe, so a good mooring. 1 Quote Link to comment Share on other sites More sharing options...
