FYI, my main pulley has a piece of reflective white tape.  Apparently left on there from the person that set the RPM when my boat was commissioned.

My engine RPM at full throttle is 3100.  I have a 3 blade fixed prop.  I run it at 2500 cruising speed and the temp is at 170 degrees.  My boat has been in the water since the end of April and I haven't dove under the boat yet to clean the prop and just last weekend, I did throttle all the way up and got it to 3100.

Main Message Board / Nicro solar vent comparison
July 28, 2003, 02:19:32 PM
Does anyone find it advantageous to be able to manually turn the vent off like what is available on the Powervent 3000?  Or is the Day/Night version (much smaller) adequate without the manual shut off switch??  For those that have these vents, what are the pros and cons.  The Powervent might have some bells and whistles that may not really be necessary.  I am comparing both and would like to get some feedback on the options for each.

Thanks for the input.

Jan,
Are you sure you want to move over to the 'Dark Side'???  :D

I went to a very big Kubota tractor dealer.  This place caters to serious farming equipment.  It is like a new car dealer, but instead of cars, it's filled with gigantic combines, etc.  I gave them the SERIAL number from the Kubota tag I found that is screwed onto the block.  Even with this number, they could not find the equivalent oil filter.  They said I would have to know what Kubota tractor uses that particular diesel, then they would be able to find all the parts based on the TRACTOR model.

Go figure?

M-1 remover from Home Depot gets them really clean.  Also works great on life lines.  Does not react with the plastic to make them sticky.  Also safe on fiberglass (contrary to the new labeling.  Old copy said safe on fiberglass.  Called the company and they told me same formula, new look on can).

Good point, Charlie.  I was thinking fresh air in, fumes out.  But this makes sense.  Thanks...

Main Message Board / Blower hose
June 30, 2003, 05:12:38 AM
I recently noticed the Blower hose that's on the SB side cowl vent on the transom is connected to a plastic Y-plenum, which is located above the A/B fridge unit.  The hose is connected to two of the Y openings, but the third is not connected to anything.  It has been my understanding that when the blower motor is running (the blower motor unit is connected to the port side cowl on the transom), it blows air out of the port cowl, causing a vacuum effect in the engine compartment, drawing in fresh air from the hose connected to the SB side cowl.  But with the Y set up, not only would air be drawn from outside, it would also be drawn from the rear lazarette.  But not only that, I'm sure this compromises the amount of fresh air that is allowed to be sucked in from the SB cowl because of this third opening.  For anyone with a MkII model, I am curious if you also have the Y-plenum and if so, why is it there?  Why isn't the intake hose connected directly to the cowl vent??

Thanks,

Main Message Board / Nicro Solar Fans

Brian,
I also leave the little hatches open, locked on the first notch.  I never see any evidence of rain.  Also, I leave the head and aft cabin doors fully open for ventilation.  I've been thinking about adding a Nicro fan, putting it in the salon hatch, but haven't been able to get the nerve to do it.  I always wondered if the light which comes from that hatch would be greatly reduced due to the solar vent.

Main Message Board / Knot Meter Problems
July 02, 2003, 12:34:49 PM
Last season, my transducer would also work sporadically.  I cleaned the gunk out and it would work for a short time, then read 0.0. Since the paddle wheel was clean, but still didn't work, I figured it might be the head.  To check if the head was operating, a local marine supply shop let me borrow a new transducer.  I plugged it into the back of the head and everything worked perfectly when I spun it with my finger.  I figured it was the transducer, so I went ahead and bought the new one.  When I went to pull the original transducer out of the thru hull, it broke right in half!  I was holding the top half, and the bottom was stuck in the thru hull.  I managed to push it through, so now it's sitting in the sand at the bottom of my slip.  Apparently, the transducer is made in two halves and water was making its way into it causing it to malfunction.  When I looked at the top half, there was corrosion inside.

So maybe your problem is a transducer that is starting to get weak where the two halves are snapped together, letting water in.  Mine was only 3 years old. I called Raymarine, but they said they wouldn't honor any warranty claim.  I was surprised to see that the transducer is merely snapped together instead of the two halves permanently welded with waterproof adhesive.

It is very difficult to use. I needed to use it when one of the eyebolts came loose.  The closest marina was three hours away.  I suggest try it out before a real emergency happens.  That way you'll know how to handle it. You have to take the wheel off, and it will clear the pedestal.

Main Message Board / Gas bottle safety - or not
June 02, 2003, 06:01:16 PM
I have a MkII and also noticed that the vent hose from the propane locker is not at a correct slope.  Therefore, water does collect.  This would be dangerous because the propane gas wouldn't be vented properly.  Those of you with MkII's should check it out and re-route the hose with a sharper slope.

Hello Jack, how's that shaft seal been??

Can't help you with your particular situation, but I have a similar problem with my Acugage tank monitor.  When I press the button to give me a reading on one of the tanks, the FM gets static.  As soon as I let go of the button, it's fine. When playing a CD, there is no problem.  Maybe there is some similarity with the reason this happens and an Electrical Engineer on this site could point us in the right direction. I've tried hooking up a noise suppressor on the positive and then on the negative wire, but that didn't help.  I tried the suppressor on both the radio and the Acugage.  Also called Acugage and they couldn't give me a solution. :confused:

Dave,
I also appreciate all your help with this website!!...  I have a glitch to bring to your attention.  When clicking onto the message board, I get an error box that says:
"A runtime error has occured.  Do you wish to Debug?  Line:1   Error: Syntax Error"

When I click the YES box, I go right in with no problem.

Thanks,

Main Message Board / Interior Varnish
May 28, 2003, 05:30:24 AM
I bought a quart of the interior varnish from Catalina.  It is VERY fast drying!  Which makes me think that's why they use it, so they can speed up production.  I found that Minwax Helmsman Matte varnish looks exactly like the original factory varnish when applied to teak.  When held next to each other, can't tell the difference.
