1982 165hp merc in/out leg trouble

[kelowna cobweb]

I have had a rumble develope in above boat, at 20 mph there is a steady rumble that increases with acceleration. leg was drained and leg oil was a creamy lite brown,( water??). I was told that it probably is the gimble bearings are these tough to change, I can swing a wrench but I have never worked on boats before.what can I look for to know for certain. I could not find any filings in the leg oil, but I can't say for sure. overall starting and idling of boat has caused no problem at all. H.E.L.P.

IF noisy gets louder when steering is turned hard left are right, u-joints or gimble bearing.

is there a way to tell without having to re-filling leg with oil and trying your suggestion?? it is getting near the end of boating season here in Canada and would like to work on over the winter...... null

You probably could but I wouldn't reccomend it!!! Could cause more damage to bearings located in lower unit.<br /><br />I remember on my Mercruiser 228... "gimble" would make a racket with hard right/left turn.<br /><br />If you drained lower unit... Did you see any metal???<br /><br />Better off refilling & testing!!!
