Problem with gas and gear throttle

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

We have recently experienced some serious problems with our throttle when trying to drive forward. The engine rpms goes up as normal but the propp does not rotatate and we cant run forward. The problem started when we had used the red button that releases the gear. Now the problem comes and goes even if we dont push the button at all. Mostly it appears in narrow passages and unwanted situations. Anyone who has experienced this before?

	Sounds like the clutch not engaging. Take the cover off the back of the gear lever and give it a good lube; sorted me last year when it was being a bit silly. Simon

	Hi, Besides lubricating the gear lever and mechanism you must also lubricate the cable that connects the lever with the gearbox. WD40 is perfect for this sort of jobs. Lubricating both cables and adjusting their travel is an important job which sometimes should be left to a specialist since if you fail to adjust the gearbox cable correctly you might ruin the gearbox disk.

	Yesterday evening I made some checks that was suggested by some mechanichs. I checked that there was oil in the saildrive, that the oil was clear and did not contain water. No problems there. Then I checked that the gear lever on the saildrive was engaged when the probem occured. It was and the same with the gas cable. I also removed the gear cable from its support close to the saildrive so I could engage the gear manually and by that I was able to see that there was a possibility to push the gear lever a little bit more forward. To be sure that the gear cable would push the gear lever as much as possible I adjusted the throttle end of the cable with couple of millimieters. Unfortunatly it did not solve the problem at all. What irritates is that some days the problem does not occur at all and some days it happends several times in row. I havent been able to find out any reason or situation when it happends. I have tried to do some shifting back, neutral, forward, fast, slow etc in certain order but nothing gives a clue when the problem would occur. All cables run smoothly, all levers on the saildrive and engine moves without any problems. The throttle handle in the cockpit and the box behind where all the mecanics are fitted in is perfect (the box cant be opened btw) and moves as they should. The only conclusion there is left is that there must be something wrong in the gear box on the saildrive. What do you think?

	Since my problem with propulsion occurs only now and then and not constantly, would it be possible that there is a problem with the folding prop? I'm not much for diving under the boat when the engine is running which would be necessary to do so the prop can be visually inspected. Any one who has experience of problems with the folding prop and can tell what to look after? Its a Flexofold.

	Do you have sail drive sd 50 ? If you do this sounds like maybe cone clutch adjustment needed!

	Yes, SD 50 and 3JH4E engine. When you say adjustment, how do you mean? I ask because my mechanich is not talking about adjustments but replacing the whole cone which obviously is so much more expensier!!!

	It has to be clutch or prop. If I had your problem I would have boat lifted check prop and if in any doubt put my original fixed prop back on. The main problem is the yard likes to take your prop when they install a folding prop so I hope you have the original . I have a Kiwi prop that behaves differently to yours, when it becomes fouled I have great problem dissengaging reverse however a service on the prop and I am good for a few months The clutch is proably made of cork if it is the same as the one I own , that being the same thing that keeps wine in a bottle, as a general rule they work then break, so should not be a hit and miss problem; but life is never as expected. As you own a 370 the use of engine is optional and only for in and out of marina, maybe strap an outboard to the transom and forget the main engine! Simon

	Hi, When the clutch is engaging you can hear a certain noise like a loud click. Before deciding to do any mechanical costly work I suggest to experiment while in the marina with out releasing the ropes. There you will be able to check if the propeller opens or not without diving by the wavelets around the boat. If the propeller got stuck in the open position it is possible that you ruined the clutch cone since the propeller shaft was turning while sailing. But I still believe that since the problems started after you used the red button they are related with the lever, even if you say that it is in perfect condition. In the marina you will have the piece of mind required to run the engine with the clutch cable disconnected at the clutch unit and operate the clutch from the small lever there.
