Can Someone Tell Me How These Big Boats Can Beach Without Damage To Outboards

In this video you can see the larger boats with outboards beaching, how do the do this if they have power trim/tilt that most big boats do, my power trim/tilt will not let me do this it will rip my lower unit up and possible tear the motor off the boat.

So long as the engine is in gear it should let you do this. Power tilt and trim is a ram that holds the engine up, it's the forward force the prop applies that holds the engine against the ram.

Make sure your engine is off, put it in gear and lift the end, you'll be surprised.

Try it out of gear and it'll be a different story.

I'm trying to work out why they would have engineered it that way?

Unless it's a mod, there's no connection/interface between gearbox & tilt system afaik. There's a relief valve in the hydraulics that lets the engine kick up if it hits an obstruction (beach!) to try & reduce leg damage. The relief valve only operates at a set pressure, otherwise you wouldn't be able to use reverse gear, the engine would lift.

Not strictly true, as you'd never be able to reverse unless motor had a "reverse lock".

In most systems there's a pressure relief valve built into the powertrim, so that if you strike a submerged object, the motor is able to kick up. Strike it hard enough though, and you'll smash the lower to pieces!

So the bigger engines have a valve - is it just the smaller engines that have the lock that has to be moved when using reverse??

Knowing that my tiller versions had one I thought that the remote versions had one but it was within the remotes / gear levers?

Every day we learn.......
