Mercruiser 470 to Mercruiser 140 Swap Question

[ddrieck]

Will a Merc 140 engine bolt to the Merc 470 bell housing?
Also, will the drive coupler from the Merc 470 work with the Merc 140?

Yes on flywheel cover (aka bellhousing) The 470 uses a standard Chevy bolt pattern.
not sure on the coupler probably best to cross check part numbers of the engine serial numbers
