Thanks Misdirection,
Someone made a 2" access hole on the STBD side and then hacked into the factory wire tube/conduit. It does help to see what is going on in there but there is no way I could drill a hole through the hull at that angle. A 4" hole may give you the right angle, not sure. I can get my wire to that hole but not down to the engine bay because that hole is smaller that the factory tube/conduit. I think I may have to put a bunch of drill bit extensions together and give the underside a shot first. if that doesn't work, then I might try your plan. I have fresh water temp sensors on my exhaust in that area and already snapped one off climbing around in my spacious engine bay. Don't want to do it again especially when they are not cheap and have to come from the UK ugh!
