hello hello, got forwarded here by some fellow fishermen, hope someone can help, here's the dilemma...<br /><br />i have an 81 johnson evinrude 35hp OB, recently i was heading back to the launch after a day out on the lake and the engine start vibrating terribly, which in turn vibrated the hell out of my boat, i lowered the throttle and continued back to the launch, the engine never cut out or died..just vibrated very bad..<br /><br />the following week i took it out and again it vibrated but this time i lost all motion, the prop stopped turning...so this is where i am<br /><br />my guess is that the leg is shot, the transmission is gone or i ran out of gear oil...<br /><br />any thoughts on this would be greatly appreciated, thank you<br /><br />scott

Hi,Scott.<br />With the boat on the trailer, in neutral, engine off, rotate the prop by hand. Observve the propshaft. It should stay in the center. If not, the propshaft is bent.<br />Also note the condition of the prop itself. grab it,and see if you can get any 'wiggle'.<br />Now, stick in forward, and rotate the prop.It should click in one direction,and not go in the other. If it does, the hub has 'spun-out'. You will need to take it off and send it to a prop shop.For around 35buks, they will rehub and ballance it. I'm pretty sure this happened AFTER the intial problem.<br />Click on this link for "lower units 101". It should guide you thru basic lower unit inspection.<br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=17;t=011919
