Outdrive & tach problems

[scook]

Yeah, the boat was "professionally" rewired when I got it, and it took me a couple of hours to trace out and get power to a replacement anchor light - I'll definitely check the tach wiring.

About the outdrive - it's a Mercruiser 3.7L(?) - it's a 170 engine. MJ, you may need to hold on to your A with both hands, but I can't find anything that looks like tilt locks on it anywhere - what am I missing? Are they manual/electric/? I'll check the fluid/wiring to the pump/etc. as soon as I can get back to it. Good news is that I got it into the shop (thought it might be too tall) so I won't freeze MAO working on it.
