    Default Trim sender part number?

    Engine - 4.3PLKD #3868618Cobra SX legWellcraft 21 sl 1997I have been trying to get a replacement trim sender for the above boat. I have removed the part and it reads on the sender itself 3855074. The Volvo dealers tell me they do not recognise this part, but another company has provided me with part number 3863007. I have the part, but it looks different to what is already there. It does have the 3 wires for connection though. I think it may fit but do not want to damgage it as it cost 62 GBP. Any ideas????

    The 3863007 number is for 1998-2005 drives.The LK model you have is a 97. You should have sender number 3854842.

    I have a 1996 Four Winns with 4.3 L Volvo Venta SX drive that has a trim sender unit with number on it that reads 3855074 and 3855535 29-H-U Mexico. I need to replace it and found 3855535 replaces 3863007. I was wondering if this part number (3855535) is correct or is 3854842 correct according to Don S information. Thanks
