5.7 coupler

[n2ostroker]

Quick question. I pulled the motor in my boat to do some maintenance. Paint/clean bilge, new bilge pump, rear main seal, etc. I noticed last time I was out it felt like I might had spun the hub on my prop. I was wrong. The couple had spun some. Still hooked up good after the one incident. I don't want to pull the motor again later though.

Motor is a 5.7 Mercruiser. Has an Alpha 1 Gen1 outdrive.
So here's the question. Are the smallblock and V6 couplers the same?

This is off the 14" flywheel and the V6 couplers look the same as mine. If they are I can get one cheap I just don't have one on hand to check.
Any help appreciated. Thanks

If its a 4.3 litre v6 then they should be the same.

Re: 5.7 coupler

Awesome! Thanks. I know Chevy/Mercruiser used the same bellhousing. Was pretty sure they were the same coupler. There were 2 of the triangle ones used. One had the greaseable snout/shaft, the other didn't. Mine is the older style.
