Before I spend the £150 on a new one (for a customer so although it hurts, not quite as much!) anyone happen to have a tacho sender for a yanmar lying about?
This is for a 6LP but used in a lot of there engines. Part # 128170-91160
I don't happen to have one, but always worth trying Dave Crawfords in Lymington if you would like to source a secondhand one, as they seem to have all sorts of Yanmar and Mercruiser parts from engines/drives they've broken up.
