walleyemaniac Posted July 7, 2018 Share Posted July 7, 2018 I have an ‘88 Yamaha outboard 90hp. Needs exhaust manifold gasket replaced. Was told the mid-section of the motor comes apart from the bottom up. Have to remove the lower unit, which I’ve done before, then keep working up from there. Can anyone add an advice to this? Hoping the power head does not have to be removed. Thanks in advance for any help. Quote Link to comment Share on other sites More sharing options...
