Engine removal and new sail drive

So on Friday, Mike the Volvo Penta engineer took out the engine to replace the sail drive, (this is the gear box that drives the propeller) and hull diaphragm (This is the rubber seal that stops sea water entering between the sail drive and boat hull) Whilst Mike is at it, I have asked him to service the engine and generator. He is back in 2 weeks to refit it all and in the meantime Ill check the rest of the engine room equipment which is hard to get to with the engine in place. Ill replace and service parts as required and give the engine bay a thorough degrease and clean following the engine removal.

Mike noticed what appear to be cracks in the fibreglass base that support and where the engine is bolted down on the starboard side. In the back of my mind, I am worried these may have been caused last year when the crane lifting the boat had one of the lifting strops caught on the underside of the sail drive. They soon realised and dropped the boat back in the water, but the whole 17 tonne boat weight would have been momentarily on the underside of the sail drive. And the possible cause of the suspect cracks.

I am taking photos and sending of to Hallberg Rassy and the marine surveyor who surveyed the boat when I brought her back in 2021 for advice. I am not sure they are cracks. Hopefully they are simple fiberglass crease marks from when the boat was manufactured. But again, better to be safe than sorry!
