Trim/Tilt relays

I had a problem yesterday with my trim/tilt and am pretty sure it's one of the relays, so I've decided I'm going to replace both.

Can anyone give me any information on a reliable online Evinrude OEM parts supplier in the UK that isn't going to cost me an arm and a leg that I can order them from?

Mike Vincent at South Coast Marine in Christchurch is yer man.

Are you 100% sure it's the TNT relay? I've just had an interesting one that initially pointed to a relay, but turned out to be a broken wire in the loom. (advantage of having twin engines is that you can swap parts around to isolate faults)

Thanks for the heads up Dave, I'll give him a call tomorrow.

First I assumed that one relay operated the trim in and the other the trim out, that might well be the case but I couldn't operate trim down which was working without the other relay in position.

After a bit of playing and swapping the relays around I managed to get it working again (and it worked all day long), but it seems like a sticking relay and experience tells me it's probably on it's way out. I'll get the simple things done first and worry about more complicated things if buying a couple of new relays doesn't sort the problem.

What engine is it? Evinrude usually have just the one relay that does up & down.

It's a di 150hp 2004. The handbook shows two relays for the trim tilt. Perhaps the other is for the faster tilt?

Thanks for your help Dave. Couldn't really justify spending 60 for a pair of relays so had a hunt around and bought a pair for under a 5er.

The only difference I can see is a resistor across the coil on the original relays is missing from the cheaper ones. Something to do with EMF or something.

60 quid Sheesh! Glad you got sorted though. A fiver sounds a lot better. The resistor across the coil is to reduce the back EMF when the coil is switched off, it reduces the arcing across the tilt switch contacts. It could be a resistor or a diode, various methods are used, but they all have the same result. Not having one might mean the trim switch contacts burn/wear faster, but I doubt it. What you might get is a crackle on the radio when you operate the trim, due to the extra arcing, but for 55 quid you could put up with it. The other solution is to cross match the ones on the old relays & solder some across the coils on the new ones, pennies from Maplins.
