I've done a search, and looked at mercruiser parts online. I'm trying to re-assemble my 454 Gen VI that someone else disassembled.

I also need a new coupler and can't find that on Mercruiser parts online either.

Any info????

i've seen them on ebay,just type in mercruiser in your search,prices vary from $75-350,just keep checking,depending on your hurry.

Don't want prices. I want the online diagrams...

Gen 6 Coupler The couplers are on the crankshaft page, don't ask me why.

That's why I couldnt find it. Where's the cheapest place to get one?

You just got that info from the guy that has the best prices.

Need some pics of an installed motor. Got the shortblock together, now I need an idea of where the wiring harnesses go. Anybody got any pics of their 454's in the boat???
