[C320-list] FW: Re: Fuel Gauges

[Karl Mielenhausen _/)]

Mike,



No problems with the sender or gauge on hull 690. I've learned that 1/2 on the gauge is really about 8.5 gallons remaining (assuming a 19 gal tank capacity). I've found that fuel efficiency is best at lowest rpms, but we have been cautioned not to cruise at less than 2400 rpm.

you will find the 7th item on the list is an Excel spreadsheet of my experiences with fuel efficiency.

  4.5 seem really low for the sweet spot. My sweet spot is around 6+ it is at the slower RPM when I get vibrations. The fact that the vibration is at your feet sounds like maybe your prop or alignment? On my old Catalina 28 I had a zinc come lose on the shaft that made it vibrate.

I have owned 2 Catalina’s and neither of them have had gauges that work.  I have heard this is common for all boats.  The manual states fuel consumption at ½ gallon per hour at 2800 RPMs, I’m rarely up this high, so I figure it is safe to go 40 hours on the 20-gallon tank.  I guess what I’m really asking is – is it worth replacing the sending unit, gauge, etc., if it’s going to only last a short while; or should I just continue to guestimate?       While I’m 
sort of on the subject of RPMs, my boat has a “sweet spot� at around 2000 RPMs, which pushes it along at around 4.5 knots.  When it gets above that, I feel a small vibration at my feet.  How much vibration is normal?      I also have to share my joy with the results of McLube Sailkote.  Before Sailkote it would take everything I had to get the main sail ¾ up the mast and the last ¼ was tough even with the winch.  Now I can pull it all the way to the top without straining.  I also applied it to the shift lever and throttle lever shafts at the pedestal and talk about smooth.  Awesome product!!!       Thanks!
