Hi all
 
Last summer we had a Scandinavian circumnavigation. Arriving north of Norway from Russia, we discovered oil leakage from the motor. A closer look on the engine revealed three missing bolts fixing the gear to the engine. Yet another two bolts where loose and could be screwed without using tools. We could only find one of the three missing bolts in the oil spill below the engine.
 
When the engine was taken out in a VP service shop, the two other bolts were found. It turned out that they had fallen down between the gear and the oil pan, causing the head of the bolt to penetrate the oil pan due to the vibration.
 
The running hours at the time this was discovered was approximate 600 hours.
 
Have any of you heard about or experienced such a case?

My 505ís D2-75 was delivered with loose oil pan bolts, discovered following a profuse oil leak. Someone at the factory neglected to torque them to spec, I suspect.

Your experience suggests Iíll check the transmission housing bolts on my next visit.

Sloppy work.

on my previous yacht i had Volvo D1-30, had multiple oil and fluid leaks from just about everywhere all as a result of bolts not tight.

I put this down to being a Monday morning or Friday afternoon engine build but clearly not.

Hi

Does anyone know if the gear/sail drive is assembled to the engine by Volvo Penta or by Hanse?

Hej Bjarne,
when I visited the yard 2013 to see my boat in the build phase I saw that the engine/saildrive combination came ready assembled in wooden crates. At that time Hanse had standardized on Volvo.
