Mercruiser 454 question

[Black Owl]

Okay, who can answer a question about a Mercruiser 454 w/Bravo I drive assembly?

 

Need to know if it is possible to shift from forward to reverse while under load?

 

 

Thanks much

Normally, though, you have to go to neutral first to prevent damage to the gears

I think you are talking about a two lever control and I'm pretty sure you can't even get the lever out of gear let along force it into reverse. I think the way the control is made it won't allow things like that to happen.

I think a bravo drive is a single control.

 

In any case, l whether single or dual lever, the control is designed to prevent you from shifting unless the throttle is backed off.

 

You could certainaly defeat the mechanism, but I can't imagine why you'd want to. As a practical matter I believe the dogs are undercut (like on a motorcycle) and will resist disengaging while under power.

u will damage the lower unit....if u are just over idle going slow to dock it wont hurt..but goin across the lake u will cause damage to the lower unit and or the transom 454 has a lot of torque...along with going backwards to fast could fill the boat maybe evan sink it.. why would u ask ? ?

you could probably do it ONCE...

 

Don't know how the Mercruiser lower unit works, but YEARS ago the Johnson/Evenrude used magnets and a spring that tightened like a "Chinese handcuff" to shift. There were no "dogs". If that is the case here there would be no problem making the shift. There would however most likely be LOTS of problems after the shift, if it was done much above idle.
