Just finished the job. Since the boat is at my other house, i ordered the entire oil cooler assembly from babbitts, and all the bolts and rings, etc. (they were cheap compared to the oil cooler)

Upon inspection - sure enough - bolt three had snapped off with the threads remaining in the old oil cooler. Took about 3 hours to replace the oil cooler. If i did it again, i could do it in maybe 1 hour. Get three small hose clamps and don't bother trying to re-use the old spring clamps - mine were rusty aways. I was able to re-use the o rings etc. The bottom oil hose is kinda a bitch, very short and you are working in the blind to put it back on. Getting it off by prying with a screw driver is where you trash the old spring clamp. Also figured out that a bolt head will fit into the oil filter threaded fitment (it has like a 11 or 12 metric allen in the center) and the biggest allen at the hardware store was a 10mm and that was a little too loose. Then we found a part like a turnbuckle that was a perfect fit and i was able to easy back out the old oil fitment. Three bolts hold the oil cooler to the block - when putting back on - put the two lower hoses on first, when the cooler is in position under the exhaust manifold (I did not remove the exhaust manifold). Do the longer water exhaust hose first and tighten the clamp. Then do the short oil hose. With both lower hoses on and clamped - next you install the oil cooler to the block. You need to get the top bolt started first (important step) then the lower front bolt then the rear bolt. Then it racks right in. Go ahead and replace your oil filter - since all your oil is in the bilge you might as well do your oil change and filter change. I also replaced the #3 bolt on the other engine with a replacement part. Don't know if that will really prevent another failure on the other engine, but WTH, metal fatigue etc. I am keeping my old cooler - as i my try to tap out the broken bolt and have a spare on hand for when the other side fails. Net net, then only thing I really need was the oil cooler assembly.
