These 840281 guides are not available, from Volvo Penta. They are having some issue with the
suppliers of these and can’t get them out so they have NLA them.
However, I do have a work around that we use. We take 3582561 which is for the TAMD41P and
have them machined at a shop so they are identical to the 2000 series (or MD6/7) engines.
We have used them for quite a while and they work well.
This is not a Volvo Penta solution (Volvo Penta has no solution) but one that we engineered.
