I have done this with a nanni (marinised kubota). Not a volvo
, but maybe the idea is similar.
I unbolted the gearbox
, unlinked the prop shaft [and pushed it aft - via the PSS seal]. The gear
box was left resting on the hull
behind the engine
The rear end of the engine was 'attacked' then and the rear oil seal
I also changed an engine mount at the same time by adding support to the aft 'half' of the engine - by a chain winch
attached to an eye bolt I put through the floor of the cockpit
We did this in a marina as I was unsure of what else I might find/cause when I started the job.
The most expensive cost was the marina fee!
I was very unsure of myself and my abilities before this, but felt better after the job was done.
