1998 Datamarine Chartlink D7000XTC GPS with Datamarine D7012SA smart GPS antenna, cable, mounting bracket, etc. 12V power. Working fine when I took this GPS out of my boat. It uses the new type C-Map NT or NT+ cartridges (not included) and is very accurate. It has all the fancy features and...

I want to get ready to start a Great Circle Route cruise in 2006. Over the winter I'm going to clean the cooling system on my 8V71TI's. I plan to have the heat exchangers boiled out at a radiator shop, take off the intercoolers and check for fouling, and take off the shower heads and clean...

I want to get the service manuals for my 1978 8V71TI's and I'm wondering if there's a less expensive place to order them than through my local DD distributor? Thanks, Doug Shuman

Some recent threads have indicated that installing or removing a prop by using a wood block to keep it from turning while you tighten or loosen a prop nut is a bad idea. However, this month's Passage Maker magazine article by the PMM's technical editor and VP of operations for Zimmerman Marine...

While cruising the last few weeks, I have occasionally been down in the aft stateroom (1978 53MY) while the Admiral was at the helm, usually with the autopilot, cruising 12 to 15 knots. I heard a strong vibration sound 3 or 4 times per minute, so I opened the lazarette lid and looked in. I saw...

Yesterday my starboard tach failed, so of course I can't use the synch either. It turned out to be that little flex cable marine gear oil pump to the tach drive. As noted by somebody else, the squared end had rounded off and just spins in the drive. How do you get that little cable out of the...

I'm 3 days into a 28 day cruise and both engines get up over 185 if I run at 2000 RPM. I also see a light steam or mist in the exhaust behind the boat when running. I pull back to 1700 and they stay cool (around 175) but still emit some steam or mist in the exhaust. Sea strainers are clean...

Seems to me that on weekends and evenings this Owner's Forum site is VERY slow. It frequently takes 10 seconds to 10 minutes just to load a page, it gets hung up and won't load or won't upload a posting. In "off hours" it's fine. Is it just me or does somebody there monitor server capacity...

For my shaft log hose clamps, I switched the prior owner's perf screw clamps over to beefy T-bolt clamps. The question is, how tight do you tighten these, since they seem to just get tighter and tighter as you crank the nut on the T-bolt. I don't wnat to split the hose material or crush the...

Duh... So I was replacing the sealant and splines in my 53MY windshields and managed to crack one by using steel tools too close to glass. It just cracked the outside pane of sandwich glass, but I got'ta replace it. It's flat and rectangular, no curves. What type of glass do you use? I'll...

Based on my prop shaft gland work, I'm interested in how engine alignment is achieved on a 1978 53MY with Allison M20 gears and 2" prop shafts. There's nothing on this in the owners manual. Thanks, Doug Shuman

I have a port prop shaft packing gland that I never touched for 2 years since I bought the boat (1978 53MY, 2" shafts), and it never leaked a drop except when the boat was splashed after 5 months in winter storage. This spring, I noticed that it wobbles when the shaft turns and it's a little...

Maybe it's "operator error" but I can't use the smiles in the new forum. When I do click on one, it just puts in the typing version :( like that. What am I doing wrong? OOPS! Now I see that it converts them to the graphics after you hit "submit". As Gilda used to say.........NEVER MIND ...

Doug Langley, I notice that a number of us are using the "reply" button at the bottom of the last reply, instead of the "new reply" button at the bottom of the whole thread. That forces a lengthy quote of the last reply at the start of the new reply and makes the whole thing too long and too...

I understand from battery manufacturers that one of the larger limiting things to battery life is "cycling" and that a battery may have 1,000 or 2,000 cycles in it's useful life. The bugaboo is that a "cycle" is when it's recharged for any amount, goes up to full charge and the charger goes...
