1964 5.5hp Johnson seahorse

[mike2us]

This motor has been sitting around for several years. First thing i did was change the spark plugs and check for spark. Plenty of spark. I then disassembled the Carb and cleaned it up. Got a carb kit from the local johnson/rudy dealer and installed that. Put everything back together and BAM... started on 1st pull. Now my issue. WHITE smoke... WHITE smoke... coming from the bucket of water. From what I've read in these forums it's coming from the exhuast. There's water coming out of the pee hole, so it looks like the water pump is working. At the moment the gas/oil mixer is 32:1. I know it should be 50:1, but someone told me to go 32:1 first to lube up the engine since it's been laying around for so long. I'm planning on using 50:1 today to see if there's a difference. Sorry this is so long, but 1 more question. Since all i've been doing has been in a can filled with water, I would like to take it out on a boat Monday and see how it goes. With the smoke so bad,, should i do this or wait until I clear up the smoke issue. Thank You...<br /><br />P.S. Great site with alot of info.. Glad I found it. My first Motor and would not have been this far along without all this good info..

Take it out and run it. You always see more smoke in the can, plus you are running quite rich on your oil mix. Make sure you clean your plugs before running it out on the water, that extra oil could be fouling the plugs a bit.

Leave it at 32:1. Your motor has several plain bronze bearings in it and it really needs the extra oil. It also has three rings per piston which means more friction that later motors with only two. It'll smoke a bit more, but it'll last a lot longer.<br /><br />If you aren't sure of when the waterpump was last changed - change it. It's cheap insurance. Even though it is currently pumping, it may be cracked, worn, dry rotted, etc. and only waiting to fail - generally when you're in the path of a large cruiser with a cocktail captain at the helm... New impellers are available through your local Johnrude dealer, NAPA, or even right here on iboats.<br /><br />Also, just to assure yourself - take a peak under the plate on top of the flywheel. If the coils aren't cracked or "chalky" looking, then you're probably good to go. It's not uncommon for the original coils of that era to be cracked, even though they may make spark. They will also tend to fail at the most inopportune time... It is very rare that a coil without cracks goes bad, so if yours are good and clean, then you're probably good to go...<br /><br />- Scott

Thank You both for your reponses..<br /><br />I'm only going to take it out on a little river with a small boat and not wake.. Just want to run it around a little. <br /><br />As for the water pump,, I'm planning on changing that soon, no matter what... Want to have this motor in tip top shape for crabbing.. <br /><br />Since you mentioned the flywheel.. hahahahhaha,, I've tried very hard to get under there to look at everything, but it won't budge, I'm very worried about hitting that crank shaft to hard and breaking it... Since I'm getting good spark right now, and it starts, I'm putting that task on the back burner for now. <br /><br />I will let you know how everything goes after Monday.. Thanks again..
