Stiff throttles.

Hi. With friction undone throttle levers stiff and need nearly full range of movement to increase revs. Boat new to me. Tia

Welcome to the forum!

Mine's not as bad but never been oiled and stiffer than I'd like. Looking to buy something like this tool and disconnect the cables at the engine as it's simpler than working the throttle end (although that would give a small gravity advantage). Will also work on our cycles. Others have used for car clutch cables etc.
HYDRAULIC MOTORCYCLE CABLE OILER

Edit: I just purchased it and will review it in due course.

Personally for the 30 quid ish apiece for new cable I couldnt be arsed peeing about trying to oil them. They start to stick because either the liner is worn out or the strands are starting to corrode causing the stiffness. Oil might free them off for a while but probably only delaying the inevitable need to replace them

I'd agree but it's the degree of effort to change that puts me off, also I don't know what length to order.

Take the old ones out first probably. Also the little flaps on the quadrant are meant to Rev the engine in neutral and there is no connection to the carbs. Is it another cable to do this? Last point where can I get them for thirty?

If they are Teleflex cables they should have identifying numbers on them that describe the length, so you can easily order identical replacements? That's assuming you can see the cable sheath at some point...

I remember a chap back in the Havasu Barney days built a high pressure oiler, and also concocted his own lube mix. His conclusion was once they get stiff, oiling them maybe bought him another season, which he was happy to take, but he still needed to be planning to replace them the following winter.

Sure but in my case not too bad and not much use each season. Just want to do some basic preventative maintenance, maybe I'd change them and not much difference? I think OP definitely needs to take that route. In my case it's subjective.

That would be my thinking. Once gummed up or worn then replace but lubricate each season so as that replacement point is as far ahead as possible.

Back to the old days of British motorbikes.
Common to take the brake & throttle cables off, hang them up and then make a plasticine cup round the highest end.
Fill cup with engine oil & allow to run down inside & drip out of the bottom.
I do the same with the trailer brake cables which have a convenient built in cup already in place!

Here’s a great vid that may give you an idea. This could potentially be done with the cables in situ.

If they are stiff to the point where they are not really working I'd go with replace and lubricate new cables regularly with a good quality grease or oil. just a side thought, have you disconnected the engine end and tried the throttle for freedom of movement i.e. is it defo the cables stiff and not the engine linkage ?
