Engine Out (AGAIN) :-(

Expecting a seized piston ring or two, found that all three con rods are bent 🙁

New Fuel Tank

Relocating Control Panel and Morse

Here are some pics:

On the left is the larger Johnsom pump impeller, on the right is the earlier Jabsco.

Removing the Volvo MD2B Engine From A Westerly Centaur

Photos taken when removing the Volvo Penta MD2B from Gemini:


Next time I would wrap the engine in an old duvet to further protect the woodwork.

Continuing Oil Leak Woes

Plate between block and timing gear housing leaks when engine cranked:

But, not when the raw water pump rear cover is removed:

It looks like the leak is only there when the system is pressurised,and the oil seems to come, not from the rear of the pump cover but from between the engine block and the front plate.

The parts explosion:



It looks like there are 2 missing bolts securing the plate to the block.

(Jan 2018 – NB. I think back in 2016 I purchassed and fitted these 2 bolts and that cured the leak. Now the engine has been rebuilt the leak is back. Is it possible that when it was rebuilt these 2 bolts have been again left off again? It would be relatively easy to put all the outside bolts in and miss these 2 inner ones?)

This picture show a new plate being held up in front of the gears of the gears just to give an idea of what is behind:



Raw Water Strainer

The raw water strainer has always been located under the port quarter berth, which has been an irritation. It is now located next to the engine! Plus, an ‘L’ valve so that the water can be pumped from another location if required
