Trolling Valves

I have a pair of Yanmar 6ly3-ETPs w/ ZF-280 gears.

There are electronic trolling valves installed but previous owner dissconected them at the helm control.

Anyone know why one would disconnect them ?

Any experience w reconnecting? There is no male plug in the vicinity of the empty female end of the plug

If there is no matching plugs maybe they werenít ever hooked up.
Question: How slow can you go at idle in gear?

If the valves are unknowingly turned on while traveling at normals speeds, expensive transmission damage occurs. One way to make sure this can’t happen is to disconnect them. Since I never plan to fish from my current boat, my valves are permanently locked close.

I guess its possible
but there is a light on the dash that indicates when the troll valve is on and they are def installed on the gearbox.

About 5.5-6kts

Which can be fast for striped bass or even BFT when trolling downsea

Also would like to have the valves so I could creep forward if I had a fish on and needed to help for a few seconds in the cockpit

Its impossible for this condition to happen w these electronic valves

5.5 kts is pretty fast for dead idle. If you have them and think you would use them, no reason not to hook them up again.

Its very fast.

I just need to figure out how to hook them up.

Not sure where to pick the harness up from the motors.

We have ZF 280-1A gears, and FWIW neither our gears nor our trolling valves are electronic. There's a separate cable running from manual Teleflex trolling valve controls at the helm...

Your 280s are electronic? Maybe the connection from helm controls feeds into
(or connects to) a harness that runs from gear levers to gears?

Yes, my valves and shift control are all electronically controlled. No mechanical cables. There is a wire bundle that runs from the helm control head (levers) and a disconnected plug that is also connected to the trolling indicator light on the dash. All wired together. This must get connected to a harness someplace but there is no mating end visible anywhere. Info is sparse on the Internet for this as well.

I think there should be an interface that plugs into the stbd and port Electronic interface modules. They are easily accessible. Need a manual but hard to find.

On some, there is a pulse wheel and sensor on the output coupling that plugs into the harness. This way the system can actually monitor shaft rpm and vary the t-valve to keep the setting constant. Maybe that is what is missing.

What brand controls? Is there an electrical drawing or installation manual for the controls?

Yanmar electronic controls

Was just speaking w my mechanic

Should be a wire bundle that goes from he processor to he controls

I have the pigtail at the dash
Just need the one hat runs from the processor

Must be stashed in the dash somewhere

Trolling Valve

I am a marine controls distributor so here are the facts about solenoid shift trolling valves. These can only be used with electronic engine control systems (so if you look in the engine room you will find your processors), you can contact me with the info off the label and I will help you out. Almost all marine electronic control systems have built in safeties to prevent any damage to the transmission while in the troll mode. If you advance the throttle while in the troll mode the electronic controls will close the trolling valve in full lock up position until you come back to the lower rpm.

In the old days you had a manual cable that operated the troll and sometimes captains would forget they were in troll mode and throttle up to get on plane. If run like this for any length of time it would burn the clutch pack requiring the transmission to be rebuilt.

You can reach me at 904-260-9756 or at edr@controlmastersinc.com for assistance.

Safe Boating!
