I suggest that you just buy the correct item.
Just realised from the another thread you are an authoritative source! Thanks for the spec. Here's why I want to do away with the standard breather. It's mounted directly atop the case adjacent to the filler plug
. Aside from the breather, the gearbox
tight. In a situation where a narrow and shallow bilge
takes on water the incline of the engine
can allow the shaft coupler to splash water over the transmission and the location and height of the standard breather exposes it to this splashing, risking water ingress into the transmission (especially at the moment as the steel
cap on the breather has dissolved into rust flakes!).
Our boat has a narrow and shallow engine bilge
, and whilst it has never happened to me because I look after my boat (well, except on first launch after purchase
), the PO's apparently had problems keeping water out of this area. It only takes about 10 litres of water for the problem to occur on this vessel. Having said that, I can see a failure of the prop shaft seal
or leaking raw water
system has the potential to cause the issue in a short space of time. With a modified breather it will be impossible for water to enter the transmission as once the water reaches a certain level it will spill over to the main bilge. We purchased the boat with 19 engine hours and even now 12 months later I'm still a little concerned there may be some water induced transmission damage as the transmission makes a noticeable click/clunk sound when engaging forward gear
(reverse is fine). I installed a new Beta from scratch in our last boat that by coincidence had the same model transmission attached and don't recall
having any issue in this regard.
