Phantom 46 Volvo TAMD75P Oil Pressure & Blown Engine

[EasyT]

Thanks for that. Spoke to my Lawyer this morning who said the courts would have expected me to give them a chance to repair, but having failed I still have the right of return under the SoGA. Spoke to a litigation specialist who explained that as the engine constitutes a "significant" part of the supply and therefore the complete vessel is not of merchantable quality. However if they were to replace the engine with a new unit this would be a reasonable response, and would mitigate my legal claim. If not then I can nominate to 'not accept' the complete vessel and ask for my money back. I was told to call and inform them of this fact, which I have now done - and now await a response. Apparently I am also entitled to a loan/charter for the period that I am without the boat....

Re: Phantom 46 Volvo TAMD75P Oil Pressure & Blown

There you go, Stbd engine was out of spec on oil pressure when you registered 150psi (max spec 94psi), ignoring whether this is the same as the Port motor or not.

Whether the temps were out of spec will depend on the actual values rather thann differences, the specs will allow for a 34 deg F variation between engines with each being in spec (assuming one thermostat has just opened @ 160 and the other is fully open @194 - this is unlikely though without an external factor coming into play).

Stick to the SoGA and refuse to take part in any discussion that includes the word "warranty" - 1yr, 2yrs or expired makes no difference.

The only way I would expect a calorifier to make any difference to the running temp is if it is installed such that it is still in circuit when the thermostat is closed but as this is giving preference for hot water over the potential health of the engine I would have thought this would be non-preferred practice if it substantially altered the running temp of the engine. Even then it should only alter the temp while heating the water, once the calorifier is up to temp it should have minimal effect on the heat loss from the engine and the motor temp should return to normal (unless the crew start using the hot water in large quantities of course!).

Volvo warranty

My boat was 2003 built and delv. March 2003.

Two years Volvo warranty. Used to be 3yrs but the continentals who always had 2yrs cried 'foul!'. I blame the French.....

You have to be careful and have the delv hand over bit stamped up - then the £500 6 months /100hrs service- then the 12months £1000 job and......

Re: Hot water

<< it is still in circuit when the thermostat is closed >>

Every boat hot water system I have seen IS plumbed this way else one would never get any heat into the calorifier until the thermostat opens as the engine reaches running temp. All systems I have used certainly do get some warmth into the water much earlier. As I posted earlier, we have never belted it with 'cold' engines but the calorifier engine doesn't seem to take much longer to heat up. I suspect there is not "that much" extra circulating water in the circuit but the water in the calorifier will keep 'taking' the heat for some time so that engine thermostat just opens very slightly later and opens less than its compatriot until the calorifer is hot

Re: Hot water

I agree - also on my boat I have a windscreen demister that works by blowing air throu pipes that run below the screen containing hot water from you know where. I guess there is a lot of volume there that 'returns' cooler than when it left.

Re: Hot water

But my full post said "...if it substantially altered the running temp of the engine". Once in a steady state with the calorifier warmed up then both engines should be able to hold the same temp (unless large amounts of hot water are continually drawn off causing the engine to be over-cooled. Sorry if I wasn't clear....

Re: Hot water

I believe its still two years warrenty on Volvo marine Engines over 300 BHP fitted with orginal equipment

I think we are agreeing

<<Even then it should only alter the temp while heating the water, once the calorifier is up to temp it should have minimal effect >>

Agreed 100% but I was merely saying that I think that IS the way they are plumbed and I DON'T think it should give a 20 degree lower running temperature at all.

Personally I'd be very suspicious of the reassurance given to mjf.

Re: in hot water

Once warmed up both my temp gauges read approx the same.my calorifier water heating system is plumbed directly into the freshwater side of the cooling water(via isolation valve) system with no obvious thermostatic control involved.

Seem to recall.

somebody else here suffered a piston failure due to oil spray designed to cool underside of piston crown not reaching to its target.

Re: Volvo warranty

Your right it is 2yrs. Thanks for the advice on the stamps, at the moment I have the invoices not the stamps.....

Re: Seem to recall.

Ref:-

"somebody else here suffered a piston failure due to oil spray designed to cool underside of piston crown not reaching to its target. "

This sounds similar to the info I got from the dealers. They said No 2 cylinder had become highly polished before the failure and <something I didn't understand> to the underside on the piston, BUT we can't be sure?

Well who can be sure?

Re: in hot water

Yes OG

for the clarification of others, the thermostat I was referring to is the one in the fresh water system that opens up to the heat exchangers just as a car thermostat allows the heater matrix to heat up with the engine circulating water before it opens up to require flow through the underbonnet radiator to maintain correct operating temperature.
Phew what a sentence - sort of free-flow (sic) of thought
