caterpillar marine diesel problems

I have heard the RNLI are pulling out all the caterpillar marine diesel engines in their fleet due to problems and are replacing them with myMtu engines ! Anyone know if this is true and if so what the problems are ? And yes one of our boats have a Cat C7 engine :/

From what I know they have tried MTU's in Seven Class and they worked very well. The new Shannon class is having Scannia engines but the Tamar is still running Cat's. I know Cat have been way over priced on parts and the RNLI dont have the money as they used to so they have to cut back.

CATs are noisey, thirsty and bulletproof. Finning servicing is eyewatering, that also maybe a factor.

Yes, our local lifeboat is a severn & the Engineer was saying that the V12 Cats are to be replaced with V10 MTUs (German) He said the new engines are shorter, lighter & more powerfull

CATS

Are overpriced, overrated, thirsty and parts are even more kidney-taking than my Volvo's - parts of them are made from cheap chocolate, that melt under any kind of pressure - would only touch one with someone else's money.
The cheeky bastards will only stick to their pretend warranty if you send them a sample of the oil when you change it -- and they charge you 100 odd quid for the pleasure....

Hold on is that similar to Cummins ?? -- i think it is.........

May they both sink on the same boat...

U've never really equated lightness and extra power with reliability and long life, hey but call me old fashioned.

Severn & Trent CAT engines were uprated to 115/120% nominal output, and were fairly well abused on service calls (i.e. 0-flat sticks with limited warmup).

New engines are bigger, more powerful, but downrated at 80% nominal - so should make a big difference to life.
