Changing single lever to twin lever

Me and my ald man have just been talking about changing his single levers for his twin inboards to 2x twin levers. And it got me thinking if I could change mine to a twin lever. I prefer using twin levers as I find them quicker and more responsive to use.
Anyone ever tried the conversion? And were does the best prices for both the unit and the links for the cables?

You could get a Teleflex twin lever unit from Nautiquipe (stevetheboat on here)
Your 33c cables from the Yam control box should fit directly.

If you go down this route, there's nothing stopping you engaging/disengaging gears when the throttle is above idle setting, which isn't good. Someone inexperienced could grab the wrong lever to throttle back and end up hitting it into reverse at wot.

Also, you'll need a new trim switch and somewhere to fit it.

What would be the benefit on a single O/B rig?

With out sounding patronising, Single lever means the lever controls both gears and throttle. So you would have two for two engines and one for one. Twin levers normally come with one lever longer than the other. The main lever controls the throttle and the smaller one controls the gears.
I just like them over single lever. You can keep the motor in gear with no revs and just blip rather than that clunk and pause you get with singles. Really nice when mooring.

Sorry missed your post mate.

I'd go for the ones with different sized levers and let no tucker near it
Was thinking of fitting the kill switch, ignition and trim on the console.

Something tells me you'll come to grief with that setup if you land awkwardly.

You could be right there Nos. But the distance between the two should be enough and the console is wider than me (one of those BMC cast off's) so no chance of kneeing it either.
I'm throwing loads of ideas around about everything to do with this 5.4. Hope to be able to start work on it soon.

Yes, I fully understood the concept, but thanks for explaining for anyone that didn't.

I still don't see an advantage. If properly set-up, a single lever engages into gear at very little over tickover rpm and once engaged the loading drops the revs even lower. Whereas, with a two lever set-up there is the potential for banging into gear with a pile of revs on.

It engages at tickover RPM. The gear cable moves its full extent (fwd and rev) before the throttle is actuated.

Exactly the point I made in an earlier post

Yeah, yeah, but where's the benefit of Matey Boy's two lever set-up?

which seemed like you didn't know

It's all down to personal pref, I find them more precise to use and more responsive.

I have to say I really can't see one. Sorry JSP

Unless fiddling with two Knobs at once is what you like doing of course

Having used both systems I much prefer a single lever, but I suppose it is personal.

No problem nasher
Always wanted two knobs for extra pleasure

Like I say I like the set up but it's not to say I'll be doing it. Just floating ideas.

I can't see any benefit, unless he's running a jet drive.

Unless newer controls are different you push the single lever, it engages gear and then goes. With the twins your already in gear letting you blip the throttle.

If you're suggesting going into gear at more than tickover you'll have a smashed box very quickly.

No, your already in gear and can blip the throttle.

You can do that with a single lever though
