Check the main ground, at the battery and at the motor.

I have the same engine so will be interested to hear the result...

As already said, I would remove and clean the battery connectors as it could be an earth problem. Could also be a starter motor issue -it may be momentarily 'frozen'.

If that was the case, the trim would work.

As you said,it'll be a poor connection or joint. I'd be looking at all the heavy duty cable connections (including the crimpings, and specifically any soldered joints if someone has soldered any of the joins) between the engine and battery,plus the battery isolator.
Given that all the other stuff on the boat works,I'd look at connections over the isolator.
If the nav lights are working at full brightness, there'll be more than enough power getting through the isolator switch to make a trim or starter solenoid click, even if there's not enough power to run the starter/trim motors.

This is unless of course the isolator is solely for the engine.

i would like to say thanks for all comments and advise

method

i cleaned the battery leads/ isolator switch and leads/ main battery leads that bolted to the engine all ok.

when i tried to crank the engine all dead / tilt/ trim still dead just a little trickle noise and the clocks/ instruments readings went faded.
i unbolted the main battery leads off the engine and touched them together. no arcing or sparks happened .
i then took the battery to halfords even though it was trickle charged up.the cranking reading was 64% not great but enough to crank the engine up.

i then called a friend who had and understud volt meters. he tested all through battery to battery switch ok /switch to main engine ok which read 12.4v enough to crank the engine,
but when i turned the ignition key the reading on the engine was nearly nil volts. something was shorting/retracting the current.

i own a 650 ribeye which as a factory fitted 12v supply socket on the back bench seat upstand. the terminals on this were corroded and after a good clean and vasaline up
the engine turned over 1st time and tilt/trim worked fine.

sorry for waffling but i can now get on with my life ha ha



its all easy when the problem is found??

thank you to all member for there advise/instructions /helpful comments

Sounds like you were lucky not to have a fire on your hands!
