Looking for someone to repair a leak I have on the coupler between the prop shaft and the transmission on my starboard motor.

Contact Anclote Diesel. Wayne Hanneseck. Done me right for many years.

You have Alison MH gears? If you do seals won’t work. The coupling gets a groove worn in it and all the seals in the world won’t help. I unfortunately have done this job several times. I tried polishing the running surface up with Emory paper but it still leaked after couple hundred hours. I ended up taking the couplings to a bearing shop where they froze them and put on a new stainless running surface sleeve. That’s the only way to do it. Make sure the mechanic tightens and torques the nut that holds the coupling on properly. It’s something like 400lb and a very large socket. Fortunately I had the giant Snap On torque wrench from when I rebuilt the engines but most of these butchers use a chisel to tighten the nut. I know of one boat that the nut came loose and the shaft and coupling took out the stuffing box and almost sunk the boat. Stand over the mechanic when he does this it’s critical!!!

And then you have the perennial twin engine question: If one is bad what about the other while I am in there, have the mechanic and know the parts?

I replaced one of mine and never had another leak. I guess it depends on the wear on the mating surface. I do remember bringing in the big torque wrench from the quarry to tighten that nut.
