I think they're more of a recovery aid than anti-stuff, coz they can only come into play once you've already stuffed!

Those of you with twin engines, who's got contra-rotating gearboxes?

OK - there was an interesting post on da toob site a while ago...

I think it was fjordrafting that said after the failure of his contra rotating Evinrude, that the left hander is always weaker then the right hander.

Whadda ya reckon?

And how is the reverse gearing achieved? Surely this could/should be enginerered to be just as durable as the standard right hander? Or do Bombadier/'rude just do shite left handers?

Certainly a different gear takes the load in forward than reverse, except for some engines obtain the contra prop by reversing by running the engine backwards. As to whether one way is weaker than the other, I dunno really, you'd like to think when they designed the reverse rotation gearbox they designed it to be just as strong. I have heard if you run a normal o/b gearbox in reverse to get the contra rotation that it's a lot weaker.

with OB's I reckon it's a little weaker, but bravo's are not bothered which way you run them. (there isn't a left n right, they'll run either way)

i ran twin Evinrude Vindicators on my catamaran for two seasons and the counter rotating gearbox was actually stronger than the right hand one.
i now have twin 2.5EFI Mercs with sportmaster boxes and also have a counter rotating one and have no problems

Hi Kiwi racer

How about some pics of your boat and anything else different from NZ on the site?

Would be great to see some new boats.

Air Shots

Here's a really old air shot. This is my Grandfather, Bert Shead in Inertia in the Cowes Torquay in 1964. The boat was a Levi design built in wood by Clarkes in Cowes with a pair of straight six volvos ran about 45 miles an hour. This design was later used as the smaller of the Trintella boats. Got loads more of this stuff that I will have to scan in.
