The trim pot (alpha, starboard side) is very very easy to remove, degrease
:-), disassemble, reassemble and reinstall. I've done it but was not looking
at the range (I'm thinking it was not 270, more like 90-120). On mine, that
6 (8?) sided piece of &^%$# plastic insert had broken and therefore was
slipping. Maybe just pop it off and take a look for yourself ?


I don't run Mercruiser but BMW, I'm only interested in the technic of
this device, because my BMW-trim-sender is faulty with no chance to get
a spare part. So I'm looking what the competitors do ;-). Perhaps I can
rebuild it.
Thanks and bye, Hajo

Hope that Trim-Indicators and -senders stand for Electronics too, so it
will be the right group here for my question:
Mercruiser's trim-sender is a potentiometric one with a down-resistance
of 10 Ohms and an up-resistance of 167 Ohms. Does anybody know, whether
this 157 Ohm-difference is a fraction of a built-in standard-poti with a
full-angle of 270°? If it is a fraction only, then the max. poti-value
over a range of 270° should be about 850 Ohm, because trim/tilt (max) is
about 50°. Or is the built-in poti a special one with a max. angle of
the said 50° + some additional degrees for "mechanical" security?

Appreciating any contribution,

bye, Hajo
