The oil pressure gage on the bridge sometimes pegs (>100psi) in response to goosing the engine, or even just running it above 800 rpm. Mechanical gage in the ER shows the expected 60 psi. Sounds like an electrical problem in the gage wiring. I'll be trying to diagnose it later today, but would...

Just a heads up. I had a noisy ER blower and decided to replace both. Found one was shot. The plastic squirrel cage had disintegrated, motor was still running. The other had noisy bearings and the cage was in the initial stages of self destruct.. If you have old blowers, you probably have a...

When cruising, the cell phone/Verizon is sometimes our only link to the internet. It's slow at 19.2 Kbps, but it does work. My question is why is the HOF VERY slow? It usually takes several minutes for each page to load. Other web sites are slow, but nothing like the HOF site. Any ideas as to...

Well darn, now we have another identified gremlin and it seems related to the battery voltage. The synchronizer has been acting up and the slave engine throttle doesn't always disengage when the syncronizer is turned on. Today, I noticed the slave engine (stb) is showing 10-11 volts when the...

I got that message last night on the smart AC controller. Shut it off and restarted and it ran OK. What's the message mean? Bob

The book says the stuffing box needs three peices of 1/2" packing. Based on the height of the adjusting nuts, I'd say it's all there but I still can't slow the leak. Ideas? can I just back off the nuts and add more packing while it's in the water? I was able to do this on the trawler, but there...

Our 48MY has a new and larger exhaust system. The original configuration was designed (I'm told) for 671N's and when Hatteras offered 6V92TA's they didn't increase the exhaust pipe size :confused: , just added a diverter for part of the cooling water. After enlarging the exhaust system, the...

The diver who just cleaned the bottom speculated the running gear is over zinc'd. The 48 MY has long shafts and has three zinc's per shaft, one each on the rudders and trim tabs. The latter are probably a size larger than necessary. Anyway when he was scraping the crud off an eight month old...

A previous owner of our 48MY had the props cupped but the diameter and pitch are factory. During survey they turned up to WOT spec so I wasn't concerned. But now, I'm wondering if the cups help or hurt efficiency at our normal 8 knot cruise (1000 RPM). Any one know? It appears to be just a small...

Last summer the port stop solenoid was erratic. I changed it and had no trouble for the next 200 hours. Now on our cruise north, the new solenoid did the same thing, or didn't. The engine would not stop when the button was pressed. Holding it in slowed the motor, then it eventually stopped. I...

Our cruise north is just three days underway and gremlins have arrived that must have been hiding during the southbound stint. I'll post them in separate threads. For this one, we have a rebuilt alternator on the stb 6V92TA powering the starting and gen 8-D batteries. There is also a battery...

I finally finished the new entertainment center in Chateau de Mer and thought I'd share the result. The design idea and all sorts of help came from Walt P :) , thanks again Walt. This aft salon wall on the 48 MY series I is virtually a blank wall and looks 'plain'. Top inboard cabinet usually...

Does anyone know if Hatteras took any special precautions to minimize lightning strikes and damage? The reason for the question: We found a metal 'bar' that looked like a copper alloy sandwiched into the core of the hard top when the wet balsa was removed. It ran for and aft, but I have no idea...

Cleaned and remoted the air box drain check valves today (6V92TA) per the advice from Karl and others on the forum and found a small piece of iron in the outboard port check valve. It seems to have a slight curve to it. Pictures attached. The engine is running well, no smoke, starts easily as...

Gent's, I thought I'd start a thread on this subject since I and others are ignorant of it. Karl's reply to Mikes thread on exhaust leaks got me to look at the check valves on the 6V92's in Chateau de Mer. My guess is they have not been cleaned since the rebuilds by the PO five years ago. And...

Has anyone worked out a way to permanently store two anchors on the standard Hatt anchor platform? We use a Super Max with 200' 3/8 $g chain for our primary anchor, but I'd also like to have a Danforth H35 with 3/4 nylon up there as well and ready to deploy. Bob

Engines are 425 HP 1980 6V92TA on 1981 Series I MY. Majored 650 hours ago. Figures below are for 175 hours running time, mostly 1000-1100 rpm with occasional run ups to 2000 rpm. Engine coolant temps hold 160-165F. Oil was Mobil Delvac 1240. Figures are from Staveley Analytical, Atlanta...

I ordered a pair of the rubber covers for my GM windless foot switches. OUCH, $72! Shipping was $11 when two postage stamps would have brought them here and I'm very close to GM. GM must be in competition with WM for who charges the most. Bob

Our Series I 48MY has 105 Gal fuel in a forward centerline tank and 490 gal in the main tank aft of the engines. I tend to not run the aux tank very low because I have no idea how far down the fuel pickup tube goes. What do you think of pumping it all down to the main tank so the aux tank can...

Hi All. My Glendining syncronizer has been shutting it self off at idle. Glendining says the issue is the master engine is idling slower than the slave. My mechanic set them both to about 500 rpm last summer, but I'd like to get the port engine up to 520 rpm to correct the issue if I can. The...
