The hose barb on the injection elbow is 2.5". It has two layers of hose on it expanding to 3" which runs along the bilge through lockers in the aft cabin to FRP mufflers and then uphill (about a 3 or 4 inch rise) to the transom (I took the hose off the elbow last weekend so was able to accurately measure). The problem is that there is a low spot in the hose runs at the base of the engines that collects water. When I look down into the hose, the pooled water is only about 10 inches below the exhaust manifold, too close for comfort IMHO. I don't really have room for waterlifts unless I put them in the keel which would require lengthy hose runs. I've been trying to figure out a way to get the injection elbow higher so I can have a proper slope to the transom. I looked at making something using stainless plumbing elbows but haven't found any in 2.5". Probably will need to have something fabricated.
Dry stack and keel coolers would be great but I don't have that kind of cash ?
I noticed someone had routed the exhaust through the side of the boat. That would make the run really short but is it really advisable?
