Re: Force Tilt & Trim Pivot Rod
Re: Force Tilt & Trim Pivot Rod
I am doing same and had similar problems with bushings. At first I wanted to keepmy bushings because mercury wants $28 each and I have two engines. $110 in bushings did not sit well with me. In the end, I ended up having to cut them out by making them into swiss cheese with a drill. For replacement I used the energy suspension polyester shock-eye #98116. Use a serated knife to trim it down to proper length. It will be a very tight fit into your cylinder eyes. After installation, use well lubricated drill bit to clean out the hole to 9/16". Works perfectly and only costs $2 per bushing.<br /><br />In the end, rebuilding my trim tabs was a bad idea. I thought it was preventative maintenance that would turn out easy. Ha! Wrong, wrong, and wrong.<br /><br />Mercury does not sell all of the o-rings that you will need. Nor will the average plumbing store. I had to order them in bulk and ended up spending $90 on o-rings. If you have to trash your trim mounting shaft, don't sweat it. A better than original is available for $8 each. Use a 5/8" internally threaded aluminum shaft. The aluminum to aluminum surfaces will have fewer corrosion problems. Cut it long enough for flat washers and lockwashers on each end. Same with pivot shaft (if you ever have your motor off). Solid core industrial aluminum replacement only costs $8 and will keep your steering silky smooth for decades. Way better than mercury's $80 piece of hollow core iron.<br /><br />Here is my listing of o-rings that you will need. The part numbers are industry standard rather than gold plated mercury. I bumped the valve body up to 3/32" from 1/16" so that I could use them on shift cover. I like to replace shift cover o-ring everytime I replace the impeller. A 3/32" quad ring (versus 1/16" o-ring from merc.) makes a perfect seal everytime. You may also want to consider quad rings for your tilt piston since cleed down is common. Also, if you hydraulic line is stuck just cut the tube and use a 6 headed socket to get the fitting out. If you tear up the female threads then you're screwed. Kunifer brake line with stainless or brass fittings makes a perfect replacement. In US kunifer is marketed as "easy bend".
