Yeh, stick your VHF Aerial to the engine cowling and when it pokes you in the back of the neck, your trimming too high.

I did have an idea of a gerbil duck taped in between the bracket and the motor. A panic squeak is when the engine is just starting to Trim down, Squeak gets louder and more high pitched as you trim in.....
Could have a nest in the Jockey seat as they make Rabbits look like mary whitehouse!


Anyway, any ideas on making the sender?

I've been thinking about this too - after too many bone jarring crashes caused by me turning round to look at the engine and missing the wave.

I'm not spending another 40 or 50 quid on some electronic rubbish that's not waterproof in mist, let alone on the back of a rib. But my head only turns 75 degrees these days, so I'd like some sort of indicator.

Bicycle brake cable, or something, and some sort of indicator (end of cable and a ruler?), but I'm not sure what and I've not started on the project - but might.

Lego tecnic range? Long thin tube with a pneumatic actuator/piston at each end?

This appears to be what the 'Boatmad guys' use.

I'd ask the question over there as I'm sure I've seen pictures of them on that site.

Correct, it's what's known as a mechanical trim indicator. Downside is that the 33c cable has limited travel, so the ball joint connection is only really suitable for measuring "trim". If you wanted to tilt the motor you either have to disconnect, or go the more expensive route of a proper engine actuator. Although that is only a folded bit of s/s and a few fixings.
