Yanmar YSE8 morse control.

[Hushinish]

I have bought a single lever morse dual control from Ebay, it has 2 cables with it. I want to use it on my yacht to replace the original yse thumb lever and rod linkages from the gear lever to gearbox

Can anyone give me some information on this conversion? I've also put a post on the Yanmar discussion site.

I don't want to be the bearer of bad news, but the marine engineers I used to fit a morse on a YSE8 a few years ago (in a Snappie) advised against the single control system. They said there was too much friction to overcome. THe two lever system (I can report) works just fine! Good luck with it anyway, but I'd hate to see you go to a lot of effort to put it in, only to discover difficulties in application.

An other problem you will find is how will you stop the engine? at the moment its stopped by pulling the throttle lever all the way to a closed position if you set up your morse single lever so that the engine will still idle when changing between forward and reverse gears you will need to find some way to stop the engine. If you do have success I'd be interested to hear how you do it .
good luck.

I have one of these engines and, somewhere in the back of my mind, I think I have read that they should be operated with dual levers.

Hmm, Some very valid thoughts here! I supose I could rig an extra choke pull type cable to close the throttle completely....Better still, looks like I ought to buy the correct controls.
JohnM, do you know the make and model of your yse controls, I don't suppose you have any part numbers do you?

They were Morse. As for part nos, sorry, it was a few years ago!

interesting comment re preference for 2-lever controls. on my 3GM30 the manual insists on single-lever controls and i think using a 2-lever type invalidates the gearbox warranty.

my son-in-law when a teenager managed to wreck the gearbox on a canal boat by changing gear at full throttle so i can see where they are coming from on this.
