I have a 30 hp Johnson on my 1988 BW 13. I cannot seem to get the "Drain/Fill" plug out of the lower unit. The slot in the plug still has a decent amount of depth to get a good grab with a slotted screwdriver; but as I continue to work that could change as anyone who has ever rounded out a bolt can tell you. I am afraid to shock it too much for fear of craking lower gearcase house. How much can I shock it? How about a torch? drilling? Penetrating oils? etc... Help PS the motor runs great just thought I do some periodic maitainence.

I used to use a BIG screw driver with a square shank. then I put a wrench on the shank so that I could really twist it. by pushing straight in on the end of the handle and twisting the wrench I always got that drain plug out.good luck |

Chris, I had to use a 3/8" drive flat headed screwdriver bit on my 3/8" drive rachet. Use alot of penitrating oil. If non of the above discribed methods dont work I wouldent beat on it to hard just drill and use an easy out. Rick |

last time I had to deal with that, I had a shop change the oil. That way if the job goes bad it's their fault. They knew I had tried, and told me they had a bracket to stabilize the screwdriver. I had already tried the wrench and large flat blade routine. I wouldn't use a torch as aluminum is brittle. |

The last time I had a bolt stuck in aluminum I put ice on it for a few minutes, then it came right out. Worked for me. Zack |

Stainless steel screws, etc in aluminum are always a problem, particularly in a saltwater environment. There is a product out there commonly called "anti-seize" compound, specifically for this situation. You can get it at most Ace hardware stores, and it comes in a little can with a brush cap. It's light gray in color, and when applied to the threads, will eliminate your problem like magic! My aluminium Big John downriggers would have seized up years ago without this stuff, as would all of the fastenings on my radar arch. |
