Ijust put in a new tach and have the setting on 6p. At idle it's at 600 RPM's, as I throttle up the tach drops off line at about 1500 RPM's. Any ideas what the problem is?
I had to replace the tach meter on my 1977 85hp Johnson. At Idle the tach reads fine but when I power up the tach drops off. Any ideas what the problem is?
Has anyone ever pulled the bearing housing out and if so how is it done? I'm currently replacing the water pump assembly and have a new gear housing seal kit.
