Hi all,
We recently had a new MerCruiser 6.2L ECT BRAVO DTS (2024, 350HP) engine installed with a Bravo III X 2.20 GAS DWP drive.
While reviewing the installation, I noticed that the input shaft from the Bravo drive appears to remain partially outside the engine coupler — with about 2.5 cm (~1”) of splines still visible.
I’m not sure if this is normal, or whether the shaft is fully seated as it should be.
I’m just a concerned boat owner trying to understand if this level of engagement is acceptable.
I’ve attached a few pictures to better show what I’m referring to.
Any insights would be much appreciated!
Thanks!
