To Stuart Lochner. The exhaust manifold you sent me was in excellent condition. I sandblasted it, passivated with Phosfatizer and then painted Volvo Green. I intended to keep as a spare.

As soon as I started the boat, last june, the old manifold started leaking badly, so I had to replace it immediately and now the MD7 works nicely. With fresh water cooling installed and cooling liquid inside I hope it will last forever!!

Concerning the injection pump, as far as I know, the CAV works as well as the Bosch on the MD7: I have a CAV. The only problem is that if you let the diesel run out with the CAV you have to prime it manually and this takes about 10 minutes.
I am having some issues with my md7a. Starts it only gets50% power and grey smoke. You said it10 minutes to prime. I did not experience this. So maybe I bleed it wrong. I just put in full throttle and turned the engine over with the lower bleed screw on the pump open then repeated on the bleed screw a little higher.
