    I'm a newbie to the boating world. I've noticed a 3/8" weep hole in my transom plate that allows water to enter my splash well if there are 2 adults in the back of my 16' boat. Should there be a plug for this?

    1974 85HP Johnson timer base question

    1974 85 hp Johnson outboard, tach inop and battery not charging

    Update with my charging issue. I had a bad rectifier. I replaced the (bad) marine style rectifier with a $5 radio shack full wave bridge rectifier(25amp 50volt). Since my stator only puts out 6amps & the marine rectifier is rated at 6-10amp, I fused the output at 7.5amp. It passed the driveway...

    1974 85 hp johnson outboard cooling questions from a newbie

    I just replaced the complete water pump assy, housing and all. When hooked up to earmuffs, I get 3 streams of water out of lower unit without the motor running. When I idle the engine water trickles out of the two ports from the top. I'm thinking I might not see a stream until it's in the water...

    I finally removed my lower unit and I'm attempting to repair my water pump with a replacement kit. I have a 18-3384 kit, but it appears the grommets won't work. Does anyone know where I can locate some grommets for the top of the pump & rod? Thanks
