Transmission dipstick

[CaptainTom]

ISO a dipstick for a Kanzaki Modle KNW10 transmission.

Trouble with the Kanzaki dipsticks is they also act as a vent for the GB. Pretty sure your local yanmar dealer can help.

Expensive at Yanmar for plastic rubbish. Emmalina is correct about the vent, which is critical but not necessarily obvious.
Alternative (posted quickly when in stock) is from Cariblue Marine in the US. Very pleased with mine and rather nicely made.
