Yes Clyde, your engine is self bleeding normally, but if the lift pump is not clicking when you turn the key all the way on, then it probably isn't working. The fuel tank is above the level of the engine, so you still get some fuel flow if the pump isn't working. Usually, the wires in the area around the fuel pump, in the top aft part of the engine get corroded or loose. Another symptom of this issue is that the buzzer for low oil pressure will not sound when the key is turned on. Good luck!

Today - hated to say it - had to get back to tranny and while there looked all over my Aqua water muffler
and could not - could not - find any valve to drain water out of muffler. Interesting.

IIRC Clyde, there is no drain valve as such on the muffler.. There should be a plug at the bottom edge of the muffler. On my boat, the plug was oriented towards the corner of the space the muffler sits in, and was very difficult to access. As a result, I opted to not trying to drain the muffler, but instead, I would shut off the raw water intake valve when cranking the engine for extended periods, as others have said in this thread. When the engine does start, I would shut it down and then open the intake valve before running the engine again. This has never damaged the impeller in my experience. I know the manual calls for draining the muffler in these situations, but sometimes we have to go with what is practical. As you mentioned, emptying the aft bunk to access the drive components, etc., is a big chore on the C310.
A neat modification I read about on this forum is to cut all the plywood inserts under the bunk pads in half, left to right. Then, to get at the tranny, raw water valve, etc., you just remove the forward cushion and the plywood covering the component you need to access. This has saved me a lot of work over the years.
I hope the tranny you mentioned is ok.
