Tell-tale tube

Hi everyone,

today while testing a honda bf90 the tell-tale tube came out of place and saltwater went inside the outboard. The trim stopped working. After detecting the problem, I washed the outboard inside with freshwater and let it dry in the sun.

The trim was ok again. Is this situation no problematic or is there any possible corrosion problems with the water ingress inside?

Regards,
Luis

Shouldn't cause any problems. I'm actually surprised the trim stopped; outboards are pretty well hardened against salt water.

Coincidence?

Hi,

it was too much coincidence :-)

But if saltwater goes to electrical connections, can't we have corrosion problems later?

Regards

Yes, you can. Usually from the wire corroding (smaller stuff than connectors, so goes quicker.) Luckily, outboards are designed with seawater in mind, and electrical systems are usually pretty well sealed.

Realistically, though, what are your options? Sell the motor, have all the wiring replaced, or live with it and hope you don't have problems. Personally, I'd go with #3.

Or he could try to identify which contacts are likely to have got wet and give them a good clean and dry and spray with WD40. If they seem to be vulnerable to future exposure then heatshrink or vaselline over the contacts etc.

RIBase
Bury teh area in Duck oil as this will expell any woisture left over where by WD40, once dry and old, will attract it - or so my car mechanic tells me!
