go right through into the lower housing of the waterpump?
I might be very wrong about that place as never delved into this before. ?
See picture for a good place to drill, remove water pump and measure TWICE or even more times...
Now I have been told , and it seems logical to cover up or fill in the the normal side water intake holes on the side of the gearcase as these would
be defunt due to the low water pick-up on the bottom of the nose cone and would just draw in air and make it all just not work.
They will not draw air but spill water, cover at least the 4 top ones, some people leave the lower holes on either side for drainage, some leave just one, I filled them all and just kept the original drain hole on the starboard side (time will tell if it is enough)
What I also want to know is.
due I have to fill in the hole from the water pump that was originally going down to the inlets, due to this trapping water and could freeze during winter months ?
or do I put a threaded plug in one of the lower holes for the release of the water ?
No
Also what about the other small hole on the side of gearbox that vents out water when I use the muffs on the hose etc, do I plug this as well ?
Not as far as I know...
To many of you this is probably something you already know and is obvious as you have seen and used nose cones and water pick ups etc.
But this is unknown territory for people here in the uk ,as to see a added cone is something that just don't happen over here.
I have never ever seen one in the flesh , and I have seen thousands of outboards including many racing set ups, and worked on a good few as well.
so a full detailed piece of what actually needs to be done when fitting wouldn't be a bad idea.
any info on this would be great,
