Outboard tilt rod material

[Durcott]

Hi folks,

just a quick one - I hope.

My old Honda BF9.9a outboard is missing its tilt adjustment rod. It's basically a 10mm round bar.

I plan to make one with a bit of stainless threaded rod and a couple of nuts, but I have an alarm bell going off about aluminium next to steel in salt water .

I THINK stainless steel will be OK inside the aluminium transom bracket castings, but I'm not 100% sure of my chemistry.

Can anyone advise before I take the plunge?

Thanks

Jeff

Personally I would prefer to use a smooth rod rather than a threaded one because there is less surface area exposed. If you are really worried about the interaction you have the option of giving the rod a thick coating of paint. Alternatively you could slip the exposed part of the rod (between the nuts) into a short length of plastic tube.

Aluminium and stainless steel are not an ideal combination in seawater but there are millions of examples that cope perfectly well with it. Unless the two were submerged there should be no problem.

The tilt pin on my Evinrude was painted steel.

I have replaced it with stainless steel... no problems


But Puff the MD's advice is good . Use plain round bar threaded only on the ends for the nuts.

A few years ago my son dropped the tilt rod from our Yamaha Malta, I couldnt get a replacement immediatly. He wanted to use the dinghy so had a mooch around the bins at the marina, found an oven shelf. A hacksaw and a pair of molegrips and a new tilt rod was born.

I saw the engine on eBay earlier this year, its 10 years since this happened and its still going strong. So no, I wouldnt worry about it.

Let me have a look in the shed first, I have a load of spares for that engine...

If it's the same as the one in the pic, PM me your address and I'll stick it in the post.
