Suzuki throttle slipping - ideas?

Xk59D · 21 September 2016, 19:33

my RC 6.8 has left hand thro, you get used to it within minutes so not a biggy.

the one thing that really pi$$es me off is the suzuki controls, if you go near a wave the power drops. i have tightened the heck out of mine and it still does it, i am literally going to put a bungee cord on when out in any weather now. the controls were just not made to be mounted the way we use them unfortunately i guess.

You have an issue somewhere for sure...I've been out in really heavy weather without any problems....are you talking about the throttle resistance setting?

Yeah bud, the resistive thing.

Something's not right if it's moving on its own...Having said that I hold the throttle in all but the most benign conditions!(over 95% of the time at a guess)....When its ROUGH or even Choppy I never take my hand off the Throttle Base (as said earlier) at all...in the "Heat of Battle" you are constanly changing speed/revs to cope with and pick your through what's in front of you...I definatly couldn't let go of the Throttle and loose that control even if I wanted to!!

The friction plate is easily accessed and adjusted as you know through the rubber grommet/cap on the side of the Throttle Handle....it might pay to disassemble and have a look see...Maybe it's be over lubricated or worn

either way I'm sure it's an easy enough fix..

I shall look at it again, it is a pita.

I can't let go of the throttle at cruise revs or ANY wave will knock it down. Even going over another ribs wake is more than enough.

If it is worn at 160 hours I shall be asking for a new one!

I've encountered this with Suzuki fly-by-wire throttles and I'd assumed they just weren't set up to cope with a thumping. The boat in question was 2x300hp and we were taking her cross channel in a well lumpy sea. When she landed in a trough, I'd have to let go of the twin throttles or I'd add an extra 200hp into the mix, but at the same time, when she bottomed out, she'd dial in a few extra horsies on her own account. This meant constant pulling back in the power.

Mine also does what I think you're talking about; loses a couple of hundred revs a time if you don't hold it open. It seems to stop happening when it gets down to about 4 - 4.5 k and it sits there quite happily. It's never caused me a massive problem since I generally have my hand on the throttle base. Mind you, it sh!t me up the first time cos I thought the engine was dying.

I think on balance I'd rather it did that and was easy to make small adjustments than stiffen it up loads and make it hard to control.

I've experienced the same, and as Willk says, if you're not careful you can dump on the power just when you don't want to. Mine was certainly cured by tightening up the friction screw.

Not had a problem with mine. Binnacle mount, friction taken up a tad.

i will tighten the life out of mine....again. it is quite tight though to put power on which is what i don't get and always annoyed me.

Old thread revive, I'm going to have to fix this properly, tightening the resistance screw inside the big cover (it is not under the rubber cap FYI, need to take the whole square cover off) does very little to help this. Clyde outboards have confirmed no issues with cables/setup they can see so DIY is required. (Myself and last tango have looked at this previously too)

I am thinking of making a 3mm carbon plate exoskeleton handle. I'll whack something into CAD and see how it works.....Can anyone see a drawback with doing this before I spend a couple of hours with CAD?

The problem (i think) is the handle is quite heavy for near vertical mounting and with normal waves it backs off. Im not sure these are designed with this type of mounting in mind?

I could probably modify the mount to put more resistance in the cables if need be rather than a carbon handle.

Or fabricate a "binnacle / wedge" to mount it more horizontally.....

buy a chunk of alloy and we can chew it down to fit

I'll give you a bell on it matey, if you are boating on Sunday you can have a nosey or I'll take it off so you can take it home.

Might be worth trying HPDE/delrin
