Sealine S37 KAD43’s DPE legs
In Spain and just got the boat back from leg bellows service and now I have -1 & -5 on the gauge. I guess they have missed a gear on the helmet when assembling. I’m pretty sure that the legs are mechanically fully down.
Can this be rectified without the boat coming back out.
I know it’s their fault and I should throw the problem back at them but at the moment I just want to go boating! (for the first time in 2 years)
 
You can adjust the trim position sensor at the top of the transom shield/ steering arm from the inside of the boat.

slacken off the small fork holding it in place and rotate the unit until the correct reading is achieved.

This is dependant on being able to reach it….being able to undo a nut …having enough adjustment angle left or right and the sender unit itself being free enough to rotate. All of which are unlikely in my experience ??

Shouldnt stop you going boating. You can hear when the trim is fully down via the note change of the trim motors. You just then move the outdrives knowing the gauge is wrong. At -5 and -1 fully down….set one on 0 and the other +4 giving you “0” on both in real life for example

Thanks Google I’ll have a look tomorrow
The S37 runs best with the trim set at the minimum all the time so it doesn’t really cause any problems other than not looking right.
I bet Volvopaul wouldn’t give a boat back like that.
 
We had this happen, and there is a recalibration process that we went through at the helm. As said above you know when both legs are "home" from sound of rams, and start from there. Recently moved to shafts so threw instructions away, but will pm them to you if I can find in old emails...

Thanks would appreciate that if you can find.
Just to double check it’s a non electronic KAD 43 so any recalibration would be mechanical. Unless there is anything that can be done at the gauge.
 
Ours was a 2010 V42, and the trim number read out in the LCD on the guages, i think, where the hours etc displayed, and you could toggle through oil pressure etc etc. The engines were d6 370s. Still digging in mails...

Thanks Andy but stop digging. Your engines are far newer and more electronic than my 2002 units. Your recalibration info won’t be relevant.
I do appreciate your effort to help me
thanks

If I can reach it and easily slacken bolt 25, looks to be a simple job.

:ROFLMAO: ? Mr Google is playing a fantastic practical joke on you. It's a menace doing it from there and the damn thing is fragile and costs 250 quid to replace when you cock it up and that's 99% if it's been in for a while and got some salt in it.. You're in the Med right? Mr Googler is afraid of the water. Much easier and quicker just to get in your trunks and with one screwdriver undo the gear strip (31) on the steering helmet. You'll notice there are corresponding dots on the gear strip and the gear wheel(26). Line them up

You may need to try one or two times to get them exact but you'll get there. Both methods will need someone on the helm to read out the numbers.

@DavidJ boat probably isn’t a leaky, oily, corroded heap of crap like yours so it will turn easily ??
 
Say what you will about my boat but it's never let me down or stranded. I cant say the same for any other boat I know of. :p
 
Thanks Bruce that certainly looks a bit more fun.
I got a bit diverted today as my batteries started to fry and I had to fork out €1000 for 5 new ones and it’s only day 1 of my holidays.
Now that I know it‘s very do-able by 2 methods (I won’t judge) I am going to relax and procrastinate a little.
Thanks guys
 
One tooth is about 4 each way .
a full movement on the clamp from mid position either left or right will give you 3 or 4 on the gauge so you might just make it .
At least the s37 has a tall engine room in the area you need to be , 13mm spanner and someone at the helm , take you 5 mins if that . You might need to cut a cable tie if the loom is attached to the fork.
