Engine trouble

So I went out for a sail today up to Lost Isle and caught a great sunset. The San Joaquin Delta has some of the best sunsets in my opinion. The wind died so I decided to fire up the iron jib and motor back. As I approached my Harbor entrance I slowed down and heard an awful rattling sound coming from what seemed like my transmission. I sped back up and the sound was gone. Slowed down again and there was that sound again. I'm thinking Wtf? So I get into my slip and put it in gear again at low idle and it's starts rattling again. Took off the engine cover and it seems to be my tranny making the noise, it goes away out of gear. Anyone have an idea what I'm dealing with? Throw out bearing possibly? It's a westerbeke 30 with a Paragon transmission and Walter V drive and yes the oil lvl is full.

Thanks
Smooth Sailing _/) _/)

Re: Engine trouble

my first guess is the damper plate. it connects to the flywheel and dampens vibration to the transmission. there may be a inspection port where you can see in there but still may be hard to see if this is the problem

Re: Engine trouble

At first it sounded like rocker arm prob, but if it is the trany anything other than removal is
going to be a godsend.

Well it wasn't actually vibrating. Everything worked fine it was just rattling at low Rpm while it gear and it was pretty loud.

Re: Engine trouble

i mentoned vibration only to describe what the purpose of the damper plate is
not to say that it would be vibrating now. broken springs in the damper plate can make a helacious noise and would be most likely to make the noise at idle

So would it still operate normally with broken springs?

Re: Engine trouble

Hmmm....interesting. What would cause something like that to break?
