      I've started doing some associated work on the above, firstly in the form of a small trolley to house/move the engine once it's removed. And happily, my starter which had been submerged, is up and running again, on the bench at least. I soaked it for a few days in a bucket of fresh water and a little detergent. Then I dismantled it, cleaned it, dried it and left it sitting in the hot press for a week or two. I lubed where needed, re-assembled and it works fine again, spinning like a tornado with the Bendix engaging etc.

      In preparation for the lift,I started disconnecting bits and pieces on the engine today, before the cold got to me. And this leads to my (latest) question. In the attached picture, you can see the assembly at the transom, which is easily removable. This will help with pulling the engine, but in each bottom corner, you can see a ledge, where the batteries would usually sit.

      These ledges are part of the deck floor and they run up in a continuous piece, up the inside of the transom. They reduce the access width of the transom by about 12" on either side. So, if and when I want to replace a section of the transom which is the full width, how do I get my full width transom section in? I'd rather not fit the transom in sections. Can I cut these ledge/floor sections out for access and then reglass them back in when I'm done?

      All this will become much clearer once the engine is out, for which I'm awaiting word on an engine hoist loan. Any thoughts welcome

        Yes you can cut the ledges out, actually the inside part is a stringer, it will have to be sistered back in properly. I think you will find the wood inside them rotted also, how far? Good question.

          Nice part with decking and bulkheads is they cut away fairly easy and go back together better than original. Typical factory boat builder leaves a lot to be desired on sealing up wood used for decking and bulkheads. They often leave wood with the hidden side left bare. Which soaks up moisture over the life of the boat. You can slice hunks out of the way with a saw, and fiberglass in new pretty easily, with the added benefit of being sealed up, by the more appreciative to longevity, owner of the boat who's doing the work himself.

          Can be fun project if you like being dusty, twisted into a pretzel, and sore in every part of your body. Quite satisfying that way

            So, everything is undone, disconnected and my neighbour will be with me in the morning, complete with his tractor and front bucket hoist, minus the bucket. I even removed the exhaust boots and elbows just to ensure that things should go as smoothly as possible. Rather than removing the two front motor mount bolts, I removed the four actual fixing coach bolts, as my trolley stand is made up to allow me to temporarily fix the motor to it, using the mounting plate holes. In doing so, I was surprised to find the coach bolts came undone with the minimal of effort.
            I thought that maybe they'd worked a bit loose over time, through vibration. Not so. When I tested this by tightening them back in again, they just kept turning, with no bite at all!!
            So, as expected, I'll be taking an in depth look at the stringers. I'm actually happy to have this opportunity, secure in the knowledge that after all is said and done, I'll have a stronger, safer, longer lasting boat. I intend to go "over the top" with any repairs, as I'm not getting any younger and don't really want to have to repeat this again. Updates to follow, watch this space and thanks for the responses to my previous questions.

              So my neighbour arrived this morning with his tractor and in 5 minutes the motor was sitting on it's trolley. Then the rains came so I didn't get much done, except to have a look see in the bilge. More rain is forecast for tomorrow, but I'll make a start in removing the inner transom assembly etc. Then I'll get into washing out the bilge really well so I can see what I'm dealing with. I'll post updates as I progress and no doubt will have plenty of questions to ask. Click image for larger version

                Looks like fun times ahead. From here it kind of looks like the motor mounts are independent of your main stringers. They might be easier to rebuild than the typical. Looking forward to seeing how your test bore holes come out. Don't be afraid to drill there and here, aft and fore. Start low, work your way towards the bow. Water works its way up into everything by capillary action, but damage occurs down low first.

                  Be sure to document where all stringers, mounts are located, from height, side to side, diagonal, front to back. Take lots of pictures, and then take some more!. You can never have to much info. Helps a lot when building the new mounts and transom.

                    As this thread has moved from being an engine problem to a transom repair/rebuild, the posts regarding the transom have been moved to the Restorations forum. Should the OP wish to continue this thread when the time comes to refit the engine, he is welcome to do so...

                    The new thread.
