That was another reason I dropped Lowrance, went from local technicians to overseas Indian tech help who seemed to know nothing about the units, it could take 45 mins simply spelling your personal details so they can give you a case number. They will also need the serial codes from the box or back of the unit, so tell him to have all that ready or his conversation with the tech guys will normally end until he has it. They will also ask what firmware version he's running and ask him to upgrade to the latest if there is one. They will most likely run him through a soft restart then a hard restart and run the unit on the boat between each of these. Ive been through this on 12in hds mk 3 units only to find firmware updates were the issue and getting the unit back to pre updates was a nightmare. This wasn't just Lowrance but Simrad evo 3 to. Im not alone with these issues, Navico need to lift their act.

Hopefully your friend has checked all electrical contacts and has a fully charged battery. For sounders I like to go direct to the 12v battery and not through any bus bars or fuse panels (still have it fused). I also like to have the battery voltage displayed on the head unit from the menu setup. The slightest bit of corrosion on wires can cause issues with sounders.

Yes,We’ve gone through all the basics , power , connections etc .

Is he the owner of the unit in question??

Yes he is. Apparently the FF completely cuts out intermittently in all modes. 
We did a thorough check of connections etc and they all seem fine.

He’s tried contacting Lowrance direct but to no avail.  

Thanks for the replies guys. Mich appreciated.I’ll pass the info on and get back to you.

Asking for a boating buddy. Is there anyone in the West Sussex /Hampshire area with one of these  who wouldn’t mind plugging in the unit to their transducer so we can test it’s operation.

Standard sonar is working fine but , downscan and sidescan are faulty and we’re trying to find out if it’s a problem with the transducer, or unit.

My 520 was a little underpowered with a 25 4T on the back. I had a 2.5 aux engine which pushed it along nicely if needed( which it did a couple of times) but the extra weight at the stern bogged it down a bit.

I moved the aux under the cuddy strapping it on top of a seat box and always carried the second fuel tank up front too when full( vent closed)

I didn’t have a stove but these two actions trimmed the boat up nicely and gave me a couple of extra knots.

When o did need the aux, it was light enough to easily manhandle on to its bracket( also kept it in better shape stowed up front.

I would check the hydraulic oil level first.

Checked it. It’s fine 

The trim tilt on my 2012 DF 100 has slowed down a lot. Seems to be the same using either switch( helm or engine)

Been told it might be the relay or connections to it. Can anyone tell me where it’s located?? And maybe ID it in a picture please.

Blimey, if I wanted to be nagged, I’d stay at home with the Missus😂😂😂

Hi Jeff,

No idea on the Optimax but good to see you on the new forum (finally!) 😉

😂😂😂I know, I know..... it’s been remiss of me but, I’m a busy bloke you know,

Did you miss me?

.

Anyone know just how much more juicy a 115 Optimax would be compared to a four stroke?

My impression is that they were about as developed as a two stroke could get. It would certainly push that Raider along nicely.
