Hi All,
I have a 1970 35-2 with an Albin A2 diesel. The trans has a flange on the output shaft which mates with the prop shaft coupler. There's only about 3" of visible shaft before the shaft enters the stuffing box.
I recently had the boat out of the water and replaced the cutlass bearing. With bearing removed, the prop shaft was up and to port in the strut.
After reassembly, I loosened the coupler and checked the alignment. I verified the coupler angle (vertical tilt) was slightly off - about 1/64" gap between the top halves of the coupler. with the bottom faces touching.
When trying to adjust the engine mounts, the studs spun inside the rubber, thus nullifying the possibility of any adjustment.
Question: How serious of a condition is this? The engine doesn't vibrate too much (it's the same whether in neutral or in drive) and the prop shaft flange spun true when checked independent of the trans.
Has anyone experienced a prop shaft or coupler failure? There was moderate corrosion on the shaft coupler. I'm wondering how concerned I need to be and whether to invest in the engine mounts or wait for the next haul out to address. I've motored twice (about 1 hr) including high revs and have had no problems.
Thanks!
