Trim/tilt relay replacement - Yamaha

On my aged Yamaha 115 2-stroke, the trim/tilt relays are in a separate box near the battery.

They have now failed (nothing sinister - just old age and dampness!) At least being close to the battery I could just bypass them with a jump lead as a workaround.

It was suggested to me there shouldn't be a problem building a new unit with a waterproof box and replacement relays. The wiring certainly isn't complicated.

However, can anyone tell me the correct rating for the relay to power the trim/tilt motor? Looking at the Aquafax and Index relays, I'd think the heavy duty 180A ones which have the post connectors rather than tabs.

I'm assuming there's nothing special about the Yamaha ones?

Any other thoughts on this?

Somewhere on the old relays the rating should be stamped/printed.

I dunno about yours, 'cos I've just got a little 40hp, but when my relays started playing up, I removed one and took it to my local friendly auto parts dept. The guy in the stores took one look at it, and immediately produced a pair off the shelf. These are obviously auto parts, not marine ones, so when I Installed 'em I simply covered 'em in silicon to waterproof 'em.
Two seasons later, they are still going strong, and if and when they need replaced, the silicon can be peeled off!

Hope this helps,
