Help PLEASE......

Hi

Can anybody recommend someone independant or who is looking for some fuel/beer money
in cornwall (truro) who could take a look art my power trim and tilt

The motor goes down as it should but on the way back up it is slow initially then once it has built up speed it comes up as it should. Well it did, now its clicking on the relay and very, very occasionally working in the up position. Can anybody help or let me know what it might be? Earth seems good as does power
Eli and colin

I've used the guys at Mylor Harbour in the past. They were very good

Trim and Tilt motor removal

Hi again

Does anybody know if the electric motor part can be removed (and replaced) from a 1996, 60hp, Mariner, 3 cylinder, power trim and tilt unit whilst the outboard is still on the boat?
Its the unit held on with four allen head stainless bolts (two at the front and two tucked away at the back).
Thanks in advance
Eli and Colin

The ram motor can be replaced.

First check its not the hydraulics if its ok then look at the top of the motor where the electric cables go in to it. Water often gets in here and this then leads to damage.

If this is the problem would disassemble the motor and pack with grease to see if that makes a difference. I nursed one for 12 months by doing this.

If needs be order a replacement one from "ARCO starting and charging" http://www.arcomarine.com/ in the US - loads cheaper than Mercury/Mariner and slightly better quality than theirs.

hydraulics

Hi NOS
The motor holds in the up postion (without) the rest and lowers smoothly. Before it virtually died the t&t motor was turning slowly (when raising the engine) and then it would pick up to normal speed after a few revolutions (the motor when not used for a while would be initially slow turning.) - would this cover testing hydraulics?
Looking where the wires go in at the top of the motor looks normal.. they cannot be pulled out from there can they for further inspection?
Cheers
Colin

I suspect you need to get the unit off and into somewhere that knows them.

It can come off with the engine left on-assuming there's not too much corrosion.
Unplug the electrics that run the PTT.
Lock the engine up on the tilt lock. There's a locking pin holding the top ram pin in-remove this then drift the pin attaching the ram to the motor out.
Remove the transom clamp anode.
Unbolt the through bolt that holds the PTT unit to the clamp, pull it out and you've got the unit off.

Are you sure that's not normal? Many engines have a position sensitive, 2-speed hydraulic unit. From full-down, it moves slowly so you can fine-tune trim, then, at a certain point, increases lift rate so you can fully raise the motor without having to sit there for 10 minutes.

Check the voltages at the battery and the motor inputs; could be that you're drawing down your power when you first hit the switch (motors tend to draw a *lot* to get going, then reduce draw as they operate.)

Luck;
