Opps I'm in trouble

JSP · 16 February 2009, 16:37

Changed my gear oil this morning and then fitted a new Yam 703 control box. All went sweet. Boats in the front garden with the transom facing my neighbours house. Filled the tank full of water, took around half hour to fill. Lowered the engine in. Turns the key and the engine banged straight into life and when to full throttle

and in gear. I've fecked something up there, what I don't know as I just did a straight swap! Trouble is at WOT the engine had emptied 90% of the water out of the flush tank and kindly deposited it all over the front of my neighbours house, from roof to garden wall. Kinda cool

But he doesn't think so. That's him on the war path! I'm in trouble!

So, why is it staying in gear? I did notice before I swapped the controls that the prop seemed to turn to much at tick over. So maybe it's nothing I've done today to change that part. I must have upset the cable setup for the revs when I attached the cables to the new control.
I tried to turn the prop by hand earlier and found very stiff and I thought it seemed in gear. That was before I changed the controls.

Any help greatly apreciated!

You did put the throttle and gear cables on the right way round? It'd be at half throttle with the lever in the neutral position, and it'd go into gear using the fast idle lever if it was the wrong way round.

can be as simple as adjustment of the cables at the engine or control box not shifting when you expect. I had a problem once where I scared myself and someone on the pontoon when after some maintainence the cable was incorrectly ajusted and I only had forward gear. When I tried a blast of throttle in reverse to slow down it just went forward faster. 10 minutes adjusting the cables fixed it.

The fast idle was down and throttle was in neutral.
As far as the revs go I must have it set up wrong as before on the 702 controls it ticked over nicely.
But it's always in gear. Had no problems with it going into reverse or forward when I took it out a couple of weeks ago but it's even in gear at tick over. Could this just be an adjustment of the cables?

Sorry misted yours and Polwarts posts.

Sounds like I could have done this! Will try swapping them over

Before you start it up again

Make sure the prop can turn freely when in neutral. When you take the cable of the throttle lever you should find the throttle is sprung so should sit at idle. So then you can line of the cable with the throttle lever at idle.

On some engines there are slightly different methods to ensure correct alignment of cables so you should read the manual to check what is recommended.

You must have done more than just got the cables incorrectly adjusted. Surely it shouldn't start in gear. There's normally a 'neutral' switch which is only closed to allow starting when the gear lever is in neutral.

That's on the control box and dependant on lever position-if the cables are badly adjusted so it's in gear when the lever is in the neutral position it'll start in gear.

Before you even start the engine, with the cowl off, operate the control and look at the engine to check the correct cables are moving to match the control box.
I would always dsiconnect at the engine end when changing anything like this.
As has already been mentioned the prop should spin freely in neutral. (Make sure the key is off, i normally make sure the killchord is pulled to)

JSP · 16 February 2009, 19:35

Ok, so it's clear I've set them up wrong. But do you think the gear cable was set up wrong in the first place seeing how there was always power to the prop pre JSP feck up? Or could it be something far more worryingly wrong?

Blizzard · 16 February 2009, 20:03

Disconnect the cables at the engine end. The gear selector should be in the middle of it's slider track, and the prop spin freely.
Also the throttle should sit at the idle position.
The remote cable ends should sit ready to connect easily without forcing them to the throttle / gear linkages.
You could start the engine without the remote cables connected if you want to check the engine over.

And going by his performance so far, it might be best to remove the prop first before starting the motor again!

Chris · 16 February 2009, 20:17

JSP you may find he prop will turn very slowly even when out of gear. My old Evinrude did this sometimes.

If the gear is engaged even at tick over it will be spinning quite fast.

Shut it diggler

Right not been able to go back out to sort it until now. Have changed the links over in the control box. Managed to download a manual for the engine. The cable for the gear slider was miles out. And I didn't do it

All sorted now thanks

Now, best way to make the peace with the bloke next door. Don't really see the problem. I mean come on, how many times has someone washed the whole front of your house for free?

Yeah it was spinning quite fast. And I know the merc I had used to spin slowly when ticking over. Prop is free to turn now and I'm going to give it a run in the tank again tomorrow. Cheers

Right, next job............................................... .....................

Nope, on the few outboards I've owned the neutral switch has been on the engine as well.

Pre '90s carbed Yam 115s don't.

JSP, before you try and fire it up, make sure that the fast idle lever is working the throttle not the gears

I'll double check but I'm feeling the urge to empty that amount of water again in one go. See if I can get next door but one this time
