I think you've already been to a few, but take note that the double acting thermostat arrangement is only as good as the ability to seal in two directions. The vulnerability of the housing is well...

So I wonder what came first at Catalina - the limitations due to engine placement and cabinet configuration, or the admonition to limit attempts at improvement?

Talking Re-engineering needed

If ever there were a group of production boats that could benefit from a jacketed system, the Catalina 30 is it. Plenty of them out there and mostly well engineered except for that exhaust.

Paragraphs 4 and 5 of your discourse explain something I had not known until now - why I could not use my digital Blue Seas ammeter to measure in the positive side. Now I know: thanks again.

Thanks for the excellent discourse. My experience is with digital meters and shunts for which Blue Seas specifies using the negative side whereas the analog can use either positive or negative.

You did indeed, and I stand corrected and upgraded. Note also they are calling for #2 to and from the panel. If you do use #2 for the panel everything upstream must be #2 or greater. I suggest the...

Shunt on the positive side would be new to me, but I do welcome the change if Blue Seas has made it. I would like to study the details on your panel since it seems my knowledge is out of date. Could...

Use of #2 as you describe is not excessive. Since the panel uses a shunt type ammeter, which will be in the negative loop if it is like other Blue Sea meters, why not put your protection (150 amp...

Please post the item number of that Blue Seas panel. If we study it for a bit I think we can give more useful answers to your questions.

No problem; just make sure the negative runs are sized the same as the positive. I use a similar panel and a #6 works well for the negative home run.

The 3% voltage drop mantra is arbitrary and violated everywhere with impunity. Read the source of it and you'll see why. Sizing of fuses should be based on actual load, not a recommendation, and we...

Clearly the 5 amp fuse is not adequate for your installation. To repeat, IMO mixing ignition, pump, alternator on the same circuit is sloppy engineering.

Careful is as careful does. The fuel pump should have it's own OPSS. In fact I have three on my boat - the third activates the alternator.

If you are running both ignition and fuel pump thru a 5 amp fuse you are taxing that fuse. Ignition be from 1 to 4 amps, typically, and the pump may want 3 or 4 amps. I like to see ignition on an...

Talking Questions come to mind

The circuit itself is a problem. The ignition circuit should be independent of the fuel pump. I recommend separate OPSS for both. If you are blowing a 10 amp fuse with both ignition and fuel pump...

After next running leave the throttle wide open overnight and place a container under the carb to see what collects, or not.
