Hi All. as part of the process of the replacement of my engine
, I'm rebuilding the waterlock muffler
, which is made of stainless steel
. It had a little bit of crevice corrosion
in it and I also decided to change the exhaust
diameter from 38 to 50mm to meet the specs of the engine
The current exhaust
has a ball valve fitted at the thruhull, which I've always found a little concerning because someone retrofitted it at some stage for a reason (the exhaust exist midships at the waterline rather than the transom). I suspect an earlier engine was destroyed by water
ingress via the exhaust, especially when considering the top of the waterlock is only a handful of inches or so below the exhaust mixer.
Anyway, I digress. The idea came to me that I could fit a 1/2" ball valve to the waterlock as a means to allow the waterlock to drain excess water
. Easy enough to do manually, but I'd really like to maybe have something operated with a morse cable so it could be turned on and off remotely.
Is the idea of a ball valve drain on the waterlock a good idea when used for the purpose of draining excess water whilst not motoring? Has anyone ever rigged up a remote
morse control for a small ball valve with any success?
