Prize Plonker - that's me

hearty pats on the back for myself and laddo (my 14yo assistant) after we'd given the stbd drive a clean up and changed the bellows. we proudly trimmed up the stbd drive so we could gaze upon our achievement in more detail. The smugness was short lived...


....finding the trim gauge reading +12 when it should be reading -4 in the full down position, put paid to a sense of completion.

Drive needs to come off again to setup correctly apparently.. doh, doh and thrice doh!!

we're spending a little while reading the manual (why didn't I do that first!) to find a way to reset the gauge sender unit and / or setup the gear rack on the steering helmet without needing to remove the drive again.

We had a frustrating day today. Changed the stbd impeller OK, but found the port pump leaking. These pumps haven't been off for years! The impellers must have done 6+ years. Hopefully the pump is serviceable, but we will probably miss the flotilla cruise to Penarth at the weekend.

AFAIK you can either just remove the plastic gear strip on the drive and turn the gear wheel or adjust the potentiometer from the engine bay; to do that, you need to loosen a nut on a clamp and turn the potentiometer until you get the correct reading; I believe you ought to put a weight on the drive to get this precise but you'll get it close enough I would have thought. Good luck - perhaps yours is different to mine in which case, just ignore me.....

If its any consolation a friend of mine got his back from a main dealer with a similar problem, not quite as wide a differential though ....

Seeing as nobody has given you the answer yet, it is a two minute rectification,undo the nylon screw holding the Rack in place on the helmet, pull the rack out align the tooth on the wheel with the notch in it with the first tooth on the rack push gently back into place.

No need to take off the drive however it may be reading wrong because the wheel or its teeth have been damaged in which case you need to replace them.

Thanks for the advice. I'll trim all the way down, reset the wheel by the marker and then adjust the servo until I get a reading of -4, no teeth broken so should work out fine. Thanks again
