Thanks for the replies, it is a95sv. I would normally fish in 10m to 40m give or take. For various reasons I don't want to get into I don't have the damaged sender so I don't know what was there originally. The plug I think it attaches to has 12 pins which I think would be side vu but it didn't have that. It may not be the original cable though. Is side vu worth having?

I have a Garmin echomap sv and find myself in need of a new transducer. It seems a rather complicated area! Based on my vast inexperience and lack of knowledge I was thinking gt23-th. Anyone got some words of wisdom!
-
My Garmin plotter does that, the boat direction comes from the fluxgate compass for the autopilot. Switch that off and the correct direction is displayed.
-
What does the boat manufacturer recommend?

There are two impellers, the one that pumps the seawater which draws from the sea through a stopcock via a strainer normally(is it clear?) then through various heat exchangers before exiting via the exhaust. In the 6 cylinder Fords this is gear driven from memory, is yours driven by a belt? The other impeller is driven by the belt in your picture and pumps coolant round the engine and heat exchanger and is a closed system, same as a car, this system is normally reliable.
When was your seawater impeller last changed? Does the seawater flow out the exhaust look reasonable?
Last time I had an overheat (6 cylinder Ford) it was a faulty oil cooler, traced with the aid of a non contact thermometer.

Wider beam?

Has the gellcoat gone there or has someone added a layer of csm?

Results 1 and 4 are odd, if the pitch 1" difference is all there is you should have got more revs.
-
Make it waterproof? Sell more expensive parts?
If you can find a parts catalogue, if the lead is available separately it will have a part number.
-
It is still faulty, I only switch the autopilot on when I need the rudder indicator.
-
I found calibrating it to be ok for a bit, it just became worse and worse over a shortish period.
-
Pull the fluxgate fuse and see if that makes a difference. I don't think my plotter has an option to ignore the fluxgate, unless I switch the autopilot off the plotter automatically uses the fluxgate for direction.
-
What about those caravan mover devices that drive the trailer wheels?
-
At that size a rib makes a lot of sense.
-
Interesting, I didn't know that. I suppose we are lucky on the West Coast, that sort of thing doesn't happen and there are few boats about to hit in poor visibility.
-
Without a fluxgate or similar the plotters should take heading from GPS. How does the radar get its heading?
-
Mine has an issue, it can be 180deg out. Doing the calibration, which is a pain trying to go so slowly, it will get fairly close but drift off over a period. The autopilot has a habit of applying full lock which is interesting at speed. Switching it off means the plotter takes direction from GPS and is accurate, I only really need it for the rudder indicator although the autopilot can be useful. Have you tried switching the thing off?
-
I suppose if you get caught out in thick fog it might be handy, not really a problem in this part of the world. Surely nobody goes out if visibility is that bad, or is expected to get that bad?
-
Perhaps, but at what cost?
-
Do you need radar?
-
ASAP supplies?

I suspect the lightest you can find.
