Don't like the sound of that much. Caught beam on in a nasty bit of sea you could be over before that sorts itself out!

Agreed - Its not the best way they could have done it - but its unlikely you will be at full throttle in those kind of conditions anyway.

They have allowed for ventilation or the boat jumping out of the water by making it so that an over rev condition has to exist for more than 10 seconds before the rev limiter cuts in.

Im sorry don't want to sound to harsh here, but if it was me wanting more speed, I think I would dump the boat and keep the engine, if speed was my main boating reason I would change to a Phantom/ring or any other make that has achieved good results in OCR, that way with that sort a HP you should get around 60mph from a 16ft with 140hp, it might sink though!!!

Agreed - the deep v hulls that are present on most ribs are not the best for speed. too much energy spent cleaving your way through the water and pushing it to either side...

Ah, that's not so bad. So you'd have to be flat chat, trimmed out to end up in that situation?

Even if i'm overrevving a little, I never go flat out for 10mins straight anyhow, so this won't be an issue.... interesting though

10 seconds - not 10 minutes

Bits of crankcase hitting you in the back of the neck my have been a givaway by then.
