    1962 28hp Head Gasket

    I finally got a new (to me) cylinder head for my RX-10 after dealing with a thread insert that came out with the plug due to stripped threads. I got the replacement head used on eBay that came off a 33hp Evinrude of the same vintage.<br /><br />I tried re-using the existing gasket but it didn't...

    5.7L Mercruiser has water in one cylinder

    I received a call from my dad tonight asking for advice on how to proceed with repairs on the motor in his Sea Ray. I'm mostly an outboard guy but know automotive four-strokes pretty well. Anyway, the shop has found water in one of the cylinders and has given my dad the option of: A. New...

    Prop Hub Spun or Other?

    I have a 1962 28hp Johnson RX-10 on the back of my 1957 Cadillac Daytona. It's a bit on the thirsty side but has proved to be nearly buletproof. Yesterday I took it out for a spin on the lake and after several miles at top speed, the engine revs picked up and the boat slowed. I did not feel...

    What did I buy?

    Today I purchased a running 1956 AD-10 M with decals on the cowl that say 5 1/2 hp. Now I find that an AD-10 is a 1956 7 1/2 hp motor. The serial number on the model plate differs from the number on the freeze plug on the powerhead. Should these match? <br /><br />Plate Serial #1437185<br...

    Johnson JW-17 3hp bogs down

    I have a 1961 Johnson JW-17 3hp that is a little hard to start but the main problem is that it will run for about ten minutes and then begins to act either fuel starved of overheated.<br /><br />So far I've put in a carb kit (I kept the old float in it) and a new impeller. When the motor starts...

    Thanks for all the help!

    Thanks to all who offered advice, I was able to remove the powerhead from my 1962 RX-10 28hp in order to replace the upper shift rod. Everything went smoothly until I lifted the powerhead off and half the gasket stayed behind and tore in half.<br /><br />I was able to trace the pieces of the...

    Powerhead Bolt Questions

    I'm going to pull the powerhead off my 1962 Johnson RX-10 28hp this weekend to replace the upper shift rod. The screws that hold the powerhead to the leg are rusty and I'd like to replace them. I removed one so that I could take it to the hardware store. <br /><br />Today, I bought some...

    Removing Powerhead

    After trying to repair the broken upper shift rod on my 1962 RX-10 28hp by using a brass sleave and JB Weld, I've come to the conclusion that I need to seperate the powerhead from the leg in order to replace the upper shift rod. The "mickey mouse" repair only lasted a few days of use.<br /><br...

    Broken Shift Rod on 1962 28hp

    Last week while I was out on a local lake, my trusty old Johnson RX-10 would not shift our of forward gear. Hoping for the best, I removed the inspection plate where the upper and lower shift rods connect and was disappointed to see that they were still connected. When I pulled the L/U, I...
