propeller runs anti clockwise?

[sailorden]

Hi,

Can any one help. I have been working on an old glastron v143 jetflite with a 50 HP Merc 500 & a mercontrol unit.
I finished working on the boat and turmed my attention to the mercontol unit and replaced the inginition switch and the choke switch and then re assembled the unit.

then on the engine i replaced the starter motor and the solenoid.

It started ok and the mercotrol seemed to work ok (if very stiff) and the propeller turmed fast when you pushed it forward in gear but there was less play when you pushed it the lever backward but at least the propeller changed direction.

All seemed well but when i put it in the water and pushed the control forward the prop turned anti clockwise and the boat moved backwards at speed. When you pulled the control backwards then the boat moved very slowly forwards>

the guy that had the engine before me was a not a good mechanic but i think he did have the bottom unit off the replace the impeller.
Could he have connected something wrong when he reassembled or is if me messing with the mercontrol?

or is it something quite common related to something different?

any help at this point would be good. I have the mercontol in two pieces and have just removed th lower leg to see if i can fix this issue once and for all.

Help please!

Regards
Sailoden

You must have a newer style control that is reversable and the shift cable is hooked up backward it should shorten the cable to shift to fwd. gear

Hi

the mercontrol is the same age as the outboard, and pushing the throttle forward will shorten the cable.

so i dont think that thats the problem, as i cant connect any other way that the way its connected.

also where do i put this message? have i put it in the wrong place?

thanks

Post the numbers off the engine. There is a very slim possibility this is a counter rotating engine.

I had a motor where someone prior to me had installed the shift cam upside down. Everything worked correctly except the prop turned the wrong way.

Yep, is right if it pulls to fwd then the shift came is upside down Mercury did not build any 500 with counter rotating units

It's not the shift cam, it's simply the splines of the shift rod being mis-aligned. Happens quite frequently when folks work without a manual. Pull the lower unit, realign the shift rod as per the book and I'll bet all will be good.

Hi

I have removed the merc 500 bottom half and religned the gear selector spline on the gear shift and all is now fine from that end. I tested the mercontrol and it seemed ok so I put every thing back together.

When i started it it pops into netural, and reverse but forward is still a problem.

What is the result of switching the cables when I can get the gear lever to go forward it goes into gear and all is well.

Maybe I have broken/worn the selector cam etc in the mercontrol & i cant work out which cable goes to which side of the Mercontrol.

At the moment the cable which is connected to the 'warm up' level goes to the gear selector and the cable which is connected to the half of the mercontol with the ingintion wiring etc goes to the throttle. Is that right?

I think the mercontrol is worn out because its so hard to put all these bits back together. Should i just get a new/recon one and go from there?

any remarks that can help me?

Regards
Saillorden

Hi all

Its fixed. As some of you suggested the cables to the Mercontrol cams etc were the wrong way around.

I must have switched them when I replaced the ignition switch and the choke button!

Learning points : (1) Always mark cables when you take them off and don't trust on memory (especially when you get a bit older!).
(2) I have learned a lot about the lower unit, gearbox, drive shafts and outboards in general!

Thanks to all, for the suggestions!
A great forum!
And now its time to get into the water and enjoy the summer!
