I was just going to do a 50/50 mix with distilled water and anti freeze from AutoZone unless you think not? Same filter then or different? Thanks

[Shawn Keulen]

Thanks for the reply. I know the service of the engines since its actually a friends boat. Boat has 1200 hours which to me is low hours. We actually have better Yanmar support in our area than we do Cummins for some reason.

Sorry I did not know that and did not think of taking pictures. It was the trolling valve spring located behind the piston the is driven by the cam on the control arm. It had a crack about 1/8″ from the end on the piston side opposite of the valve. I measured the spring as a whole then stretched to match the length trolled on it for 12 hours today and night and day difference.
Tony is it possible to purchase a spring from you?

Well with the help of the manual and Tony’s advise and since we have a blow day here I went and removed valve. I found the spring had a crack and pretty much broken about 1/8″ from the cam. I stretched the spring just over a 1/8″ to try and make up for the broken difference and it helped big time “just running in slip”. I guess now I would like to know how to buy a replacement spring? Can you help with this Tony? thanks for everyone’s help..

Is there a diagram on the valve available?

[Shawn Keulen]

Very accessible..I’m a charter boat and would be afraid if something went wrong having neither work would be bad. I can only use the “bad” one going with the wind.
Pressure drops to just above zero fully engaged and will ease into 20 range “barely moving shaft” then seems to be a slight dead spot were nothing happens even with movement of lever then past that “dead spot” it shoots to around 50ish and that’s it. If you try to ask for more you will get a “clutch grinding” noise and past that noise it jumps out. It just really seems like the lever acts like a on off switch were as the other motor it really reacts to any type of adjustment and will go to and hold a higher pressure..Just wont go to and hold that slightly higher psi I need without jumping out.

So are you saying I have a bad torsional coupling and that is why I have no adjustment on my trolling valve? Noise is for sure still there just quieter with the 424 fluid

[Shawn Keulen]

Yes tried it by hand many times on the lake and at the dock. Have replaced cable as well. Have tried vernier style cable/control as well. It will dead stop the shaft, but anything above that is more like a on off switch with not much adjustment available.
Tony I guess I don’t understand your comment “all about the ears”

[Shawn Keulen]

Put about 36 hours on the Mobil 424..No difference in trolling valve performance, but did notice the gear is quieter. It had some neutral/no load chatter that is now noticeably quieter. Pressure is the same and trolling valve performance is the same.

[Shawn Keulen]

Yes pressure gauges and shaft rpm gauges. My fluid came today so will get it put in hopefully tomorrow. My issue seems to be a bit different than yours. I just don’t really have much adjustment above dead stop.

[Shawn Keulen]

Mines not so much a “chatter” more like a gear grinding very much like not using a clutch driving a stick shift type sound

[Shawn Keulen]

Will be done this week and I have charters pretty much everyday so it will be a good test thanks
