New to me this year, a 23ft crownline with 5ltr efi.
Set off from Davis's at Cobbs(poole), go fetch some fuel from cobbs and proceed up towrds harbour entrance.3/4 way up i can smell burning rubber and its getting quite bad. Next thing, smoke starts pouring into cabin,filling that up, then smoke behind me froma pocket. Starting to panic at this time. I move away from main channel,stop and lift engine hatch to be greated by a cloud of smoke. Now i know i'm in trouble. Female friend and her 2 kids on board. Everyone on with lifejackets and pfd ready. Slowly start to head back and engine fails. Nothing else to do bar dial 999 and asked for coast guard. Within 15-20 mins and using a flare to signal them,we had poole r n l i at our side. Towed us to harbour wall and met with 2 fire engines. By this time the smoke had gone except for the smell.
Can finally see now what was burning or melting. Right hand exhaust manifold had paint bubbling up and the rubber exhaust bellows were melting and by the time they'd cooled,had gone completely brittle.
After a little investigating, turns out there was a small piece of an old impeller which had been replaced last yr in the thermostat housing restricting flow and the thermostat wasn't opening,well only a fraction.
So what a day on Sunday.
RNLI guys were superb,they'd been called in from whereever they were to come and rescue us. My hats off to them!! Firebrigade were great also,even though nothing to do for them as they were happy by the time we'd reached them and everything had cooled.
All i could think about was my crew, thoughts that this may go up in flames and having to throw then overboard. Talk about emotional.This has really dampened my spirits and is not how you want to start your season.
There must be a lesson to learn here, but one thing for sure,safety will be top of my priority from now on,not that it was ever far from away.
Main thing is everyone is ok,and kids look at it as an adventure,bless them.
 
Wow: scary stuff, but it sounds like everyone stayed calm and you handled the situation well. An overheated manifold can generate a LOT of smoke as the paint burns off. Been there!

For the future, it might be worth considering getting hold of a VHF radio and reviewing whatever extinguishers you have aboard.

Thanks s28. Yes i stayed calm and even the coast guard operator was impressed with the way things were being handled but i must say, deep down, i was a bit of a reck,but you cant lose it with kids on board.
Yes, vhf will be soon. I do have 3 fire extinguishers on board which includes one in engine bay,guess you can never have enough.
Our saving grace i guess, is that the main channel sunday late morning was almost deserted and no ships. Not a nice place to be drifting on a busy day /forums/images/graemlins/ooo.gif
 
that sounds as if you did everything you needed to.

Are there temp alarms ? Who did the replacement of the impeller last year ?
 
Thankyou. I couldn't think what else to do to be honest.It really has scarred me,i know it shouldn't, but i cant help but think, what if it happens again or its going to happen again.
Strange, i didn't hear an alarm but something turned the engine off. Engine does still turn as it was turned and run for a few seconds when back on its trailer at Davis's.
Impeller was replaced last year by previous owner who's a mechanic and experienced boater,of which 1 of my friends works for him.
The impeller he took out had literally broken up.I wasn't aware of that, all i knew was it had been replaced.
 
From your description of the overheating, it sounds like more than a stuck thermostat. Although the thermostat could cause the engine to overheat, I would still expect water to flow to the exhaust. The thermostat is to divert the cold water through or round the cylinders as required but it should always end up cooling the exhaust manifold and gases.

For you own peace of mind, you need to be certain that you have located the real cause of the failure. Why did the impellor break up on the previous occasion?
 
Hope you make a decent donation to the RNLI. Using them as a free breakdown service is the sort of thing that gets motorboaters a bad name.
 
That must have been really scary, I'm glad you are all ok. You say the bellows have gone brittle. Do you mean the rubber fittings that connect the exhaust manifold on the engine to the shield and leg on the transom? If so have you taken off the exhaust elbows and checked them? They do get clogged up and prevent water flowing through with the exhaust gases. Also worth checking the raw water filters in case of blockage there

"A free breakdown service" ????????

Where the hell did that come from?

The guy was IMO in grave and imminent danger and he did the right thing (a VHF and GPS though would be a useful addition) fire on board is a killer.

Well done you, sounds like you handled the situation calmly and bravely - Rallyveteran, I hope you never need the services of our rescue crews!
 
The way I read it the 999 call wasn't made due to the risk of fire, but was only made when the engine failed. What was wrong with the anchor?
Presumably if fire had been a risk one or all of the fire extinguishers on board would have been used.

1 Lifejackets on.
2 Make sure there is no fire, waiting a while if necessary.
3 Call a commercial towing service or ask the Coastguard to put out a marine assistance request.
4 Failing that, ask the Coastguard to call the lifeboat, but resolve to make a significant donation to their funds.
 
I'm not sure that's the right way round, apart from having L/J's on.

Notifying CG first should be a priority, in case the situation deteriorates (overheated exhaust pipe cracks and starts to flood?).

1.) You tell the Coastguard location / nature of distress etc.
2.) After discussion, the Coastguard then decide what service to deploy to assist you.
(Although they will ask if you are a member of a commercial org such as SeaStart)

Same happened to me last year due to a blocked inlet and joint between manifold & outlet melted. Not to out do you, but I had a lot of smoke and water coming in!!
Valuable experiance gained in theses type of situations and glad all worked out well for you.
You did everything right and hope it didnt put you off

Well done, I think you coped very well. If you had a VHF though any ships etc would have heard your Mayday or Pan Pan call and they should have been aware of the drifting boat in the channel ahead of them.
