    I am about to install the prop on an old Johnson CD-20, and am wondering how the cotter pin keeps the rubber prop cap on. Does it pierce the rubber? Glenn / Cudahy, WI

    Permatex Copper for Eska powerhead base?

    I have (maybe had) a good running Eska Golden Jet 500 that I decided to pull the lower unit off of, just to have a look at how the water tube was supposed to be terminated. I basically destroyed the tube as I tried to yank the LU off the exhaust housing, not knowing that the tube was actually...

    Aluminum boat: Patching screw holes below waterline

    I have an aluminum boat that had a transducer mounted below the waterline on the transom. Is there a preferred method for plugging the holes left after removing the transducer? I bought some stainless screws and washers, and thought about sandwiching some rubber washers on either side of the...

    '63 Johnson 5.5hp Overheating after Impeller Change

    I have a 1963 CD-20C that the seller of a boat I bought gave me as a non-working motor. I finally got around to replacing the impeller, and got it back together today. Put it in a tank, and it ran like a top once I got the mixture right. As it was running, I noticed that the power head was...

    I am in the process of replacing the impeller on a CD-20 I picked up, and have found that the carbon seal that is part of the upper driveshaft/powerhead seal has a chunk missing from the skirt that forms the cup that the spring sits in. I have tried, in vain, to find a part number or replacement...

    '75 Mercury 7.5 hp water pump questions

    I pulled the LU on my bargain outboard after noticing that my indicator output was more steam than stream. I guess I was a little shocked to see how much rust there was on the drive shaft where it enters the pump housing. I was scraping off the remnants of something metallic; was that the...

    Merc 75 bleed line question

    I have a '75 Mercury 75 that has a crankcase bleed line with cracks in it. I haven't actually had the motor on a boat yet, but the brief time it was running in a barrel, I did not notice any leakage, or other indication that the tubing was cracked through. Current parts lists show that the...

    Questions about '75 Merc 75

    I just picked up a 1975 Mercury 75 - ser# 4091049- for $25 on Craigslist. Sold by the original owner, who said it hasn't been run in a long time, and couldn't say if it ran or not. I have not tried starting it yet either, as I wanted to pull the plugs and check the lube in the gearcase before...
