solaris 42 help

i have an older solaris " 1978 " with yanmar 4jh2e motors. the drive is borg warner v drives . i have to remove my shafts and the skegs that support my rudders are behind the props . i dont think these transmissions have ever been removed and scares me to even attempt it ,, should i try to drill holes through my skegs and remove shaft that way or perhaps cut the skegs off and replace after the fact ?? what advice can anyone give me on replacing the cutlass bearings removing and replacing the shafts ?? they are 1 inch shafts ??? any ideas, experiences and or advice would be greatly appreciated . is there a better place on the cruisers guide to ask this question ???

Re: solaris 42 help

remove the gearboxes and disconnect the couplings ,undo the stern gland,prop shafts should slide out inboard from under the engine once the props are off

Sounds so much simpler than the sawzall approach...

bell housing has 6 or 8 bolts with geabox attached , the prop shaft coupling has 4 bolts. remove all the bolts then bell housing and gear box will just slide off .
you might have to support the engine depending on where the engine mounts are.

should be no more than 40-50 kg,no loose bits,the gear box has a splined shaft that slides into a damper plate on the back of the flywheel,which is covered by the bellhousing.

alignment should be the same as when you took it off unless you have had to undo the engine mounts.

though good idea to re-align the coupling afterwards with a feeler guage,by adjusting the engine mounts.

not rocket science!,easier than a car transmission as no clutch!
