Winter upgrade

If your leg lifts ok but will not lower until under load, try swapping the hoses from the trim pump over and see if the reverse effect happens (I.e it will now lower but will not lift). If that's the case, your pump is knackered. Talking from experience as my Bayliner had this fault and a couple of genius friends swapped it over for me and worked perfectly.

Ours suffered a similar problem (would go up but not down fully everytime) and it was a simple cure. Over enthusiastic cleaning of the ram pistons (they are shiny so were shined!) removed all forms of lubricant. A wipe down with a greasy rag on a regular basis sorted it out on the bayliner.

Both issues could be a number of things although the sticky drive is easier to find but by elimination.

What sort of alarm is it, visual i.e. flashing/fixed light or buzzer? A 2007 boat should have a diagnostic plug I would have thought and if so the engineer should have been able to plug it in. Also it's possible your engine went into overheat with the sticky thermostat and the fault needs to be cleared. Other things could be faulty sensor or bad earth somewhere. I'm not certain but I doubt it is the leg not going down, but does it coincide with it?
Your stern drive is a matter of elimination. First thoughts are that when you engage forward drive the force of the prop is compressing the rams which indicates one or both are sticking, or you may have air in the system. I think you can sort the air in system out by raising and lowering the leg fully, right to trailer height and down again five or six times.
Try this and let me know what happens. Although it should have a self air bleed lid on the reservoir this can happen.

The alarm is audio only. The engine is still the carb version so I was under the impression there were no diags, is this not the case?
The leg issue only started while on holiday, the alarm has been happening since I bought the boat. The broker engineer thinks it must be an earthing issue but this is not covered on the warranty that came when I bought the boat.
If I am cruising at 3-3500 rpm generally don't get the alarm. It mostly came on if hit a hard bump, and then would bleep on and off for a while. Sometimes though it would just bleep on for a second or so at a time with no big bump. Almost always it will come on continuous if I open the throttle full and get up to around 40mph. But the dials all show fine. All other times the alarm comes on it will just be for a second or so at a time.
Can I disconnect a sensor at a time to see if one of them is the problem?

Stern drive issue, I thought the same re air in the system. I noticed the hydrolic oil was low, topped this up and the drive has been fully up and down many times over the last few weeks. To start with it would go down from trailer level to top of trim level by itself and then stick. Later it would stick at trailer level. I had to stand on the leg to get it down enough that drive would do the rest. Not easy with the swim platform . When we moored up over night I left the leg partially down so I could get enough purchase on the water to drive the leg fully down.

thanks Mark.
I assume I will have to drain the reservoir to do that ?
As the boat is 60 miles away I think I might get the local engineer to take a look, it would be a hang upside down in a small space job I think to do this

Thats an interesting one indeed. I'm guessing in this case it's probably not our problem as she had been sitting in the water for over a week. But I will make a mental note not to polish those rams

But they're the best ones aren't they??

As you may have gathered, I'm not a marine engineer and no expert, but am pleased to help out where I can and probably like you and many others, it would be good to solve this without the expense of an engineer.
There may come a point at which you may have to call one though.

I thought we could try to deal with engine and leg separately.
I'm not sure if your engine has a plug in, I thought it ought to but not sure, but I do know the alarm covers, oil pressure, stern drive oil level and engine temperature and you have checked them as all good.

Intermittent alarm when you hit a wave at cruising speeds could be a wire or a shift in fluid level, but a continuous alarm at higher speeds is a puzzle.

I think the Temp sensor is in the Thermostat housing and will be connected to the Ignition Control Module on the Port Elbow. Check the wiring to this first, cleaning the terminals and checking for kinks.

I've got to go to work now, but on reading your issues with the stern drive lowering, you are right, you should have eliminated air pockets by now.

I would first of all, as Martin said. to eliminate external ram issues, wipe some 2-4-c grease on the ram arms and lower and raise the leg a few times to get the grease inside.

This will take out that solution if it doesn't work.

Next, there are 2 solenoids for lifting and lowering. It's important to know that when the leg stuck in the up position, whether you could hear the click from the solenoid, in addition when the leg stopped and you re-tried to lower it did you here a click?

Thanks for the further input Ian.
I'll try to get back down soon and have a look at some of these ideas.
Anyone know if my carb version of the 4.3 has a water pressure sensor,. I've spotted some mention of such things on line but not sure if this is just for the fuel injected models ?

Hi Chris
Any joy?
