I am located on the upland at a marina that deals primarially with power boats. (They are not allowed to dredge because of the oysters) The service
manager of the yard has told me that the only way to accurately align the inboard engine with a standard propeller
shaft is with the boat afloat. because blocked up on the land the hull
can be twee-eked in a different position to the natural support it receives while floating.
The vessel I am working on had two previous engine installations both with a PYI dripless seal. (The rubber was perished, and the spring rusted to a point of ineffectiveness) There was a wear mark on the inside top of the stern tube at the four O clock position.So theoretically it would seem that it is possible to push and wear the cutlass bearing out of alignment with the stern tube, and for the shaft at the inboard end to wear right through the tube over time?
So far I have installed a new cutless bearing out board, a stave bearing inboard and a new PYI dripless. I am assuming that this will give a stable point of reference, I also have a R&D marine
flexible shaft coupling 103-037 11 x 57 910-019 to fit between the flanges. To this I will match a MS2b Volvo
transmission on 2003 series Volvo penta
For those boat owners who still use 2000 series engines. Next Wave marine
systems Inc located on Vancouver's Island, Canada
have developed a bolt on kit that can be shipped anywhere in the world to protect against the splined shaft to damper failure problem. Installation
is with simple tools and does not require any machining. It can also be fitted to a damaged shaft. I have the prototype. FYI...check out the video.
I represent a non profit organisation, and have no business dealing with them beyond paying them for their work...so this is not a commercial plug
. If you are interested in more information contact them directly.

I assume that aligning my engine with feeler gauges will be simplified once the vessel is afloat.
