Clutch

Does a clutch steal power?

A clutch doesn't steal power, per se, but it can slip. Due to the mass, it can also slow the engine's spooling up and make it seem like it has less power than a non-clutched engine. Of these two, the slipping is why most people don't use a clutch on a race boat

Hydro junkie. Thank you. What do you suggest to launch a boat if I'm at the pond by myself. I'm new to these big boats. I think I can launch my big cat without a hatch. Any tips. Thanks again

While we never ran a clutch on a race boat, we do have a clutch on our inertial dyno. The advantage is that it allows starting and idling without turning anything else. It's also a safety feature in our use since it disconnects the flywheel if the engine seizes. We have tested that feature. LOL An engine doesn't have useful power much below 10,000 rpm and the clutch is solidly locked up by that rpm.

A clutch is useful when running without outside help and is a safety feature. Because the prop shouldn't be spinning while the boat is carried to the water, propeller injuries should be limited. Like an electric boat, you can put the boat in the water, go to the driver's stand or other driving position, and accelerate away. Most racers don't use clutches because they are accustomed to launching boats with running motors. The clutch is an added cost and complication. However, because of a couple of serious propeller injuries, the safety aspects are worth considering.

Thanks for the that Lohring. I have a zenoah g300. In an aeromarine avenger. And also the same engine in anew insane gen 3 hydro. I'm definitely considering it. As I'm not alway with people at the pond
