3GM30F Engine Mounts

I have a spare set of engine mounts for the above engine and is now time to replace the old ones (1200 hours). The spare set appear to be genuine Yanmar mounts with 100 moulded into the side of the rubber. However the bolt size is M14 instead of M16 currently on the engine and as specified on the Yanmar specs. Did they ever use different size bolts and is there likely to be a problem with a larger clearance between the bolt and engine bracket.

Re: 3GM30F Engine Mounts

I would be concerned.

The 3GM30(F) uses 4 mounts, all using M16 bolts.
2 x 100 (P & S) on Front end
2 x 75 (P & S) on Rear end (gear box)

The 50's and 70's use M14 bolts.
