First ever post on the MoBo forum in 18 years . . .

Just been out on a friend's Channel Island 22. It's fitted with twin Volvo 2003 turbos. Took it off the mooring and couldn't understand the handling at all - until I left the stbd engine in neutral and managed to negotiate all the moored boats safely on the port engine. Once in clear water it became obvious that the starboard engine was going astern when the morse control was pushed forward, but there may be another issue as well as the engine also seemed reluctant to rev.

Anyway, back on the mooring I opened up the engine covers and checked - both morse controls operating in the same sense relative to the gearbox, forwards pulls back on both engines and both propshafts rotating in the same direction - but boat still going astern in forward on the stbd engine and vice-versa, though with massive propwalk as well.

So - wtf is going on? The props can't be counter-rotating as the shafts are turning in the same direction . . .

Baffled . . . .

Sounds like it has a prop designed for the opposite of whatever direction the prop shaft of the stbd engine is rotating in.

I think I know what you mean . . . . didn't realise that was even possible. If thatis the case then I guess the way the morse works on that engine needs to be reversed.

Nothing new here. Some owners still like this set up .
I can think of many old brooms and the Ranger36 that doe st have contra rotating shafts .
The box on the back of the 2003 will quite easily take another prop if the owner wanted to go down the opposite rotation route..

The shafts are turning in the same direction and the morse controls are operating the same way on the gearbox, what exactly is happening? And how to fix it?

I had a single engine one a while back
The 'prop walk' was quite considerable
I don't think the twin version has the same characteristics from the ones I have helmed
As we all know a 'prop' is designed to propel a boat 'forward', therefore said propulsion item is less efficient propelling backwards per se
On launching My CI 22 once
After a re- fit
The 'pipes' had been fitted back to front
So 'ahead' was back to front
Turning to port 'she' went to starboard!
It was quite interesting to retrieve back on to the launching trailer if I remember!
I would suggest, although as you say the cables to the gearbox appear to be behaving correctly that the hydraulic pipes to said transfer mechanism are not set up correctly
Or the propellor has been fitted back to front!
:D

I have driven this boat before and it behaved perfectly normally.

Don't understand the reference to hydraulic pipes - they look like standard mechanical gearboxes, are they powered by some sort of hydraulics? AFAIK the only thing that has been changed/replaced is a morse cable. The prop has certainly not been changed.

Steering etc is perfectly normal when only the port engine is operating.

Can a morse cable be fitted so as to operate in the 'wrong' or opposite direction?

The direction of push or pull of the cable on putting gear lever fwd or astern can be chosen at the control end.

Thank you John.

So the prop on the starboard engine could be configured to provide forward thrust when the engine is going astern, and the starboard engine needs to have the morse cable set up to work in the opposite fashion ? Am I getting warm?

If so, can someone point me at a diagram/explanation on how to reverse the direction a morse operates in?

Just read the thread again, suspect the new morse cable has been fitted wrong at the control lever.

I just looked in my files, I have the Morse manual that shows how to do it as a pdf, send me an email address and I'll whizz it over to you.

Its not tricky.

There's a flat metal bar that runs across the main body of the thing, with holes at each end. When you move the main lever into forward gear, one end of the bar goes up and the other goes down. When it's in neutral the bar is horizontal, move into reverse and it goes up and down the other way. The gear cable connects to one end of this bar.

To reverse the direction of the cable, you need to move it to the other side of the control, connected to the other end of the bar, so that it moves up instead of down and vice versa. The control is designed to accept the cable at either end.

That's not exactly right. The metal plate you refer to only has a hole in one end, to switch the gear shift between push and pull you removed the plate and turn it round, then connect the cable.

I've sent Webcraft the manual via email,
 
Disconnect the the control from its mount and split it
Move gear cable to be mirror image of correct half
Note that it common for there to be more travel in forward than reverse

Fair enough, depends on the model. I don't know what would be fitted to a Channel Island 22.
