You learn something worth remembering every day

I haven't tried yet (cos it's dark...) but can you set a popup on the icommands to squeal above a certain temp and before the engine shuts down to safe mode?

Unfortunately not, which imho is a glaring omission. You can display the temp on i-command & on your N2K chartplotter, but you can't set alarm thresholds. To be fair it's so predictable not to be a problem, & only occurs in a very narrow rpm band, which is why I think it's related to the stratified fuelling.

Ah well - must just check next time out and see what speed falls into that rev range. I might even try and reproduce it with the engine temp on the screen to see when and how quickly it happens. Water here is v cold so may not be such an issue.

It's easy to replicate, just ease up the throttle to the point where she's trying to take off over the hump, but hold her back. As the revs start to pick up as you start to come on to plane, just ease the throttle back to hold the revs. You'll see the temp start to rise. It will all depend on hull & prop as to exactly if & when it happens. Some people report no problems, others do. With me it's just around the 6kn mark.

Oil injected - should take car of itself. There's no way I'd get past the first lock without oiling up!

Other option is give your aux a good blast - it will be running nicely at that kind of speed.

Also might be worth buying a couple of cheap sheets of ply & rope to dangle them by to protect the toobs in the locks. - they were designed tohandle steel hull barges & puffers.


From memory there's an Italian alongside one of the saiths in Falkirk / Bonnybridge (Forth side of the wheel) Food is good, and panorama windows mean you can keep an eye on the boat while you eat!

Another option of course is a trip right through & join the West Coasters for a tootle round the Clyde....... F&C canal Soc run regular trips & positioning moves for charters all the time so the main canal is pretty clear.

Just found this Re: Etec overheats:-
Code 31 activates SHUTDOWN at 248F (120C) and Code 43 or 69 activates S.A.F.E. at 212F (100C) on 40 - 90 HP models or
194F (90C) on 115-250 HP 60V & 90V models.

Possibly good advice but I think you are lost! No "puffer" has ever gone along the Union Canal. I also don't think you go through any original locks - in fact I think the only proper locks might be the "sea lock" and the lock from the F&C to the Falkirk Wheel basin - they are all relatively modern and there are quite nice pontoons at strategic locations along the length. Still the tunnel and the avon aqueduct are guy narrow and not exactly "tube friendly"

Aye, but you still need to negotiate a fair few miles of the F&C to get to the Wheel, and headroom or not, in 18canteen when it was built barges were made of wood or steel. Granted I haven't travelled the Union since it was opened, but a sizeable proportion of the F&C locks are originals, apart from where the lock was near a road & they've had to move it to get rid of the need to reinstate a swing bridge.


Plenty of non condensing stuff was built built specially for the route (canal is fresh water, so can use the canal water in your boiler), but a discussion around the definition of a puffer isn't going to help the OP much.


A few canal / Puffer links for those still with us:

9d280 - thanks for your clarification - I hadn't realised there were so many locks between the river and the basin at the wheel.

However I'll stand by my claim that no "clyde puffer" (regardless of boiler type) ever transited the union canal - its too narrow, has many (original) bridges and a long tunnel. However it also has no locks...

Ah, the power of association.......

The Clyde puffer is a whole different beast.



16 locks betwen the Forth & the wheel, and a further two once you get through the tunnel by the wheel. Once you're through there it's a clear run into town! Here's the map:
