1945 Sea King assistance please

[Fontanaman]

Hi Again,<br /><br />As if I don't have enought projects, I recently picked up a Montgomery Ward Sea King 5Hp from 1945. Looks pretty good, but pretty rough mechanically. Some very original repairs on it, like a bent finishing nail for the prop shear pin! I don't know if I can use it or just look at it, but it would be fun to try to get it to run. Oil mix I assume is 16:1?<br /><br />Problem #1. Engine is frozen. I tried to fill the cylinders with Marvel Oil to see if I could unlock the engine. The top cylinder holds the oil tight, but the bottom cylinder will leak out the exhaust and down the lower unit. Is this a bad sign? Any ideas on how to unseize the motor?<br /><br />Problem #2. I can't seem to get the lower unit off. BTW, The gearcase has a fitting to insert grease into the gearcase and of course was full of grease after looking inside. I guess it doesn't use hypoid oil ( I have never seen this) I removed the nut holding the gearcase and it loosens, but the driveshaft seems to be holding it. This engine is a OMC Gale I believe, so I figure the driveshaft should drop with the gearbox like all the other OMCs I have worked on. Should I simply give it some force with a mallet or am I missing something?<br /><br />Problem #3. Where the heck is the impeller?<br /><br />And of course, does anyone know a Gale cross-reference, so I might have a shot at some kind of manual and parts.<br /><br />I know this all is a long shot for info, but the folks here never cease to amaze me.<br /><br />Thanks,<br /><br />Adam

Adam,The oil runs out because the piston is in a position that uncovers the exhaust ports so its normal for the oil to run out.<br /> If the carb is on the side with a strange low speed adj. an the front of the motor it is based on the johnson TD20 5hp.<br /> Though I dont think the TD20 appeared until 1946.Are you sure about the year?<br /> The antique Outboard club may be able to help at:<br /> www.aomci.org.

Thanks for the info Spike. I suspected it had something to do with piston position. I just wasn't sure if something was broken inside and causing the fluid to go where it shouldn't. I got the model ID from the "Old Outboard Book" which has become my bible. (Highly recommended, I got mine at Barnes and Noble). Anyway, I am confident about the year and ID. The carb is on the front and has a big metal fuel adjustment knob. There is another adjustment on the side of the carb using a sping loaded screw. What about dropping that lower unit? Should the driveshaft simply separate from the powerhead? Also, any creative ideas on unsticking this engine? If I can, I may post a picture of this thing, which may help someone figure out an OMC equilvalent! I really would love to see this thing run.<br /><br />Adam

FONTANAMAN; I got this from this B.B. over a year ago.<br /><br />Remove the cylinder head, careful not to twist off any bolts, Soak top of pistons with P.B. Blaster,[much better than W.D.40], let it sit overnight, hold a small block of wood against the top of a piston and TAP with a hammer. Keep doing this until you get a small movement. Don't be frugul with the P.B. Blaster.<br /><br />When you can turn the engine over check the cylinder walls for scoring. <br /><br />Hope this helps. Happy Boating! Hal

Fontanaman, I would post at the AOMCI link listed. On some of the old motors, they had slots that line up to get the lower unit off. If forced major damage is done. Garry at OMCI can probably tell you if there is another OMC repair manual that will work for that and maybe how to get the lower unit off.
