Update:
I had a friend look at the engine last weekend, and he took out the spark plugs and saw that one was full of grime and others were relatively clean as though they were firing properly. He said it...

That's a great point. I'm going to look into that. I do have the maintenance and repair manual. I'll check it and the schematics section.
And thanks for the temp gauge correction.
It's so...

Thank you John
When I got the boat about 18 months ago, I remember it having much more "pick up" when I hit the throttle. It actually surprised me that a sailboat would move like that. Then all of a sudden, it...

Thank you Al!
I'm sure it's whatever came with the '77 Catalina 30. But I'll check it.
I have a total rats nest that I have to try to figure out. :^/

No rpm increase after half throttle
Hi all,
I just watched the Moyer Marine DVD on ignition, and have a couple questions.
It seems like my A4 doesn't reach max RPMs at full throttle. The RPMs stop increasing at about half...

I just watched the Moyer Marine DVD on ignition systems, then looked at a pic that I have of my wiring harness. ...

Thanks Dave!
I think I have a shutoff just after the tank, but it's pretty inacessible if I was in a hurry. Does it matter where the shutoff is (if I put another inline somewhere more accessible)?
And when I'm...

Cleaning the raw water filter.
I can't seem to find anything on cleaning the filter. Is it as easy as unscrewing it and cleaning it out? Do I have to beware if anything when I unscrew it? Does this look ok?
Attached is a pic...

The engine does purr. Sounds new.
