VP 120 saildrive ring anode

[AIDY]

Boats in the water so need some help... the boat will be coming out of the water for the weekend soon and i need to replace one of the threads ie... put a helicoil in to the saildrive housing to attach the ring anode. (it's only held on by one at the moment)

Before i buy a helicoil insertion kit just need to clarify the thread.... I'm guessing at a metric M6 with 1.0 pitch...

anybody have any ideas. or knows of a manual on the net, or got a ring anode in front of them ?

You could give Volvo Penta a call, either your local agent or better still, Watford. They should be able to tell you???

Just measured an old CS setscrew from the ring anode on my VP 120S leg. measures 5mm dia over threads @ pitch 1/mm.

Thanks for that so i assume wrong and it must be M5 x 0.8 same as the ones for anode on the folding prop.

if you get a chance can you tell me the length of the thread on the counter sink screw, will give me an idea of length of helicoil to buy.

thanks again /forums/images/graemlins/smile.gif

NO!, the ring anode screws are larger than the prop anode ones, allen headed. They measure 4mm over threads and are smaller pitch, 8mm/10 threads.

length under CS head for m5x1mm is 20 mm includes thickness of cs head. Thread length 15mm
