Trying to connect GPSMap 451 to a Raymarine tiller pilot. Tiller pilot is indicating no signal. What communication sentences should be switched on on the chart plotter? Garmin refer to NMEA In/Out Raymarine to NMEA +/- Which connects to which e.g "In = +" "Out = -" Do I need to connect both if...

I would asume from your thread bare comments you couldn't give a darn! It was an honest question addressed to what I'd hope might be exprienced sailors.

I have acquired the use of a sailmakers sewing machine to restitch some sail seams. The sails are dacron, but don't know the weight. the boat is a 10m sloop. What is and where can I buy suitable UV inhibited thread (polyester?) on the internet for the job. Thanks Dave

I have an old Garmin 64 from about 1994. It functions OK excepting that two rows of buttons no longer work. Garmin don't support repairs anymore. I have heard that this is a fairly common problem and can be resolved by using a small pin on each of the buttons puncturing the plastic button...

Are paddle wheel impellers compatible with most speed log displays? To be specific, should a 20 year old paddlewheel (Walkers Quadrolog) function with a modern digital display (NASA). The old impleller has a black wire, a red wire and the coax shield, whereas the new impeller is simply a coax...

Thanks, I was concerned about expansion and possible damage. I was planning to leave about 5cm at the top of the holding plate to account for some expansion. The graphs on the link leaves me feeling that plain water might be almost effective as dabbling with making up other solutions. Agree no...

The holding plate is stainless steel and custom made containing coils from a 220v danfos compressor when mains is available and from an engine driven compressor when charging batteries at sea or at anchor. As it is custom made there is a filler plug at the top. Thanks for the comments made from...

What is the liquid make up eutectic fluid within the holding plate? I need to replenish the liquid after a leak and completing repairs. Can I use the liquid from freezer packs or can I make up the solution with anti-freeze? Thanks Dave

I have an ageing, (about 20 years old) but up to now reliable Walker speed log. From the beginning of this season it reads only to a maximum of 4 knots. (I do occasionally go faster!) The impeller is properly aligned, clean and free to rotate. Any ideas what's the problem and how I can fix it...

I am in the process of replacing standing rigging and having difficulty dismantling the roller reefing to replace the fore stay. I have removed the furling drum and the norseman fitting, but cannot see how to dismantle the lower part. Should it just slide off or is there a locking mechanism...

Contemplating buying one of these, but would appreciate anyones experience before I part with the cash! Any idea if there is a chart of coverage anywhere on the web as I am based in the Med and wondered if I am in range? Thanks/Dave <hr width=100% size=1>

After over 15 years sterling service my handheld VHF battery has finally given up! Anyone know of a mail order address where I might be able to buy a replacement battery for an Icom IC-M5 handheld VHF. The battery number is IC-CM7. It has been a family friend for so long I am loath to give it...

I have recently renewed my propshaft - 304SS as 316 not available where I am! I will be fitting two shaft anodes - should I anti-foul the shaft and prop(bronze)?? thanks Dave

I am replacing my prop shaft and will need a new shaft seal 25mm shaft with 40mm(about) stern tube. Can anyone recommend any particular supplier and type together with contact details e-mail etc. Thanks

I have recently hauled out after a usual 18 months afloat to find the prop anode completely gone and serious pitting on the stainless steel shaft which requires the shaft to be renewed. The boat is GRP and I have changed nothing electrical on the boat since the last haul-out. There is a...
