    Are these zincs shot?

    '89 Johnson 70. The one on the right has been wire brushed to remove the white powdery residue. The others are unbrushed. The middle one from above the trim tab shows little erosion or powder residue. Is it doing its job? Are they due for replacement? Also, The bolt threads were well protected...

    New Steering Cable (picture)

    1989 Morse Command 2 rotary helm with cover plate removed. http://www.c-brats.com/albums/Adeline/Morse_Helm.sized.jpg . I'm not quite clear how to proceed. I know that the 2 machine screws at 7 o'clock retain the anchor plate securing the cable end. But the white nylon "back-up ring"(between...

    Rebuild older VRO2 pump?

    '89 Johnson 70. I really like the fact that this pump runs leaner @ trolling speeds while the newer OMS pumps run closer to 60:1. Repair kits are available for both the air-motor and the fuel pump for about $40.00 -vs- $360.00 for OMS. Will these 2 kits restore the unit or does the oil component...

    Fuel Sender Install

    I purchased two new Moeller cross linked polyethyline fuel tanks w/o senders. The installation will require a 2" diameter hole and 5 holes for the screws. Moeller and Tempo tanks w/ senders have a metal retaining ring with threaded holes molded into them. My tanks lack this ring. Since I won't...

    Is an '89 VRO rebuildable?

    My 1989 Johnson 70 is running the original pump and I've been advised by a respected OMC Tech to either disable oiling(preferred) or replace it with a new pump(O.M.S.?). I understand that MY pump runs less oil @ idle and that a new one simply runs 50:1 all the time. I've read that Joe Reeves...

    Synthetic Grease?

    Hi all, EZ-Loader 3100# SINGLE axle trailer for salt water use. Always used Chinese Bearings and Valvoline moly EP lithium grease w/o problems. For greater peace of mind in my advancing years, this time I'm opting for Timkens(Twice the price). I want to use the VERY BEST grease I can get. I'm...

    --------------------------------------------------------------------------------<br /> <br />My C-Dory has a number of gelcoat cracks(crazing) on the inside of her transom.

    gps interfering with vhf

    My GPS, a 10 year old Lowrance Global Map 1000 fixed chartplotter, is creating a pulsing, musical interference on my new VHF(Horizon Intrepid). It did the same thing with my old Horizon Explorer. This forces me to turn the squelch way up. The GPS receiver(antenna?) is a 5 channel...

    Larger fuel hose

    I have an '89 Johnson 70 and I would like to install a Navman 3100 fuel flow computer on my C-Dory. The Navman requires a 3/8" diameter fuel line for installation of the transducer. My entire fuel system uses 5/16" OMC hose. I could install a section of 3/8" using reducers on either side of the...

    flywheel removal 15

    I called a local repair shop to see about obtaining a flywheel holding tool and a puller so I could install a charging kit on my '89 Johnson 15. He said they're not needed. His procedure to immobilize the flywheel is to place a screwdriver between the teeth and up against the powerhead. With...

    water pump service interval

    I have an '89 Johnson 70. It is always rinsed with fresh water immediately after retrieval from salt water. I never crank the motor w/o water supply. What is the recommended service interval under these circumstances? Do older impellers fail catastrophically or simply lose their flexibility and...
