    Blown transmission on 1995 4788-gctid802234

    Returning from a 5 day stay on Sucia about a half mile out heard a bang and some grinding noise. Boat came off plane so I cut throttles and put in neutral. Thought I might have hit something but did not see anything. Checked for water coming in but nothing coming in. Long story short I then noticed transmission fluid under starboard transmission. Started limping home and at slow speed (2 knots) shaft motionless. Bumped speed up heard some grinding but shaft started to turn then it started to rotate freely. Have a. Diver coming out tomorrow to check running gear but shaft was rotating like a son of a gun at 7-8 knots. Transmission is a Hurth HSW 800 1.96

    Having a bit of trouble locating a new or rebuilt one.any thought on where to look?

    Thanks

          You may have an insurance claim if you hit something.

            Good point. It may be good to have a diver check the prop for damage. I'd contact the insurance company first to see how they want to proceed.

                  Incidentally, if this transmission is still in production (it is now called a ZF80), check around for pricing on new ones. When I replaced a ZF63A on my boat the new price was not much more than the rebuilt price and the warranty was two years instead of 90 days.

                    Thank you for all the help.

                    Had a diver out today and I did hit a dead head.

                    Insurance company is working with me at this time.

                    Best

                      "Had a diver out today and I did hit a dead head."

                      If you hit that hard carefully check all the engine mounts for fatigue or failure, bent shaft, the strut for bending or failed cutlass, dampener plate in the trans and the harmonic balancer.

                      Really look carefully at these items and pry the mounts to see if they have been compromised.

                      Good luck - hope this helps

                        Agree, Harbor Marine in Everett. In my case one transmission started slipping and when disassembled they found all parts needed to be replaced, not just the clutches. They say failure was due to extra vibration as a result of too little flywheel weight on the early Cummins installations. The new adaptor plate is recommended to minimize the problem. In my case I sprung for two new transmissions (ZF 85A)
