I have my qd-24 torn down, and I have a question about O rings. I’ll reference the crankshaft group diagram found here:

In the parts diagram, there is an O...
I have the above outboard. It doesn't have the traditional "peeing" tell tale out the back. It spits water through the exhaust port above the water line. I also see two holes (one on each side of the exhaust housing) just above the lower motor mounts that water comes out of. Are these holes...
Hi, I have a 1963 Seahorse 10 QD-24. It's been hard to start. I checked compression today and got 70 psi in the upper cylinder, and 75 psi in the lower. Does anybody know if this is good enough? If not, what's the psi range I should be at?
Hi, as the title states, I have a 1976 Mariner 3.5 2 cycle outboard. The owner's manual says to use "high quality two-stroke engine oil". This is an air cooled engine. Should I continue to use TC-W3 oil, or would I be better off using a 2 cycle oil for air cooled engines like chainsaws and...
Hi, I was looking around and found this yesterday.

Has anyone seen this before? Does anyone know where it came from? According to this, the QD series Johnson outboards (and apparently quite a few others)...
Hi, I've rebuilt the carb on my outboard. I have it idling well, but I'm not sure it's at the proper idle RPM. The repair manual says it should idle at 750 RPM. I have a digital multimeter with an engine RPM feature, but I don't think it will work on a 2 cycle engine because there's no coil or...
Hi, I just rebuilt my water pump, and am getting ready to test it in a tank. It has a 143?F thermostat. Question is, what kind temp readings should I be getting If I shoot the powerhead with an infared thermometer?
Hi, I have a 1963 seahorase 10 hp outboard. I'm rebuilding the water pump. The parts catalog doesn't show a gasket between the impeller housing and the impeller plate, or between the impeller plate and the bearing housing (lower half of the impeller housing). Should I make a gasket for...
Hi, I have a Mariner 3.5 hp outboard. I'm trying to find out what year it is. The serial # is 642S 30987. The owners manual has what I assume to be a print date of 7-1-1976. Does this year sound right for the motor? Also, I though this outboard was made by Yammaha. Any thoughts? Thanks, Doug
Hi, I have a 1980 bayliner 2250 with a Volvo AQ140 engine. When I bought it, It had one of these glass in-line filters http://seachoice.com/productdetail/ProdDetail-63432.asp between the gas tank and the fuel pump. I added a spin on canister type water separating fuel filter...
Hi, I have a '63 Johnson Seahorse 10 model QD-24B, and have a few questions. The "offical" fuel mix is 24:1, but my local dealer who does a lot of work on old Johnsons says to use 50:1. I thought I'd read that the reason for 24:1 was the use of babbit bearings in the connecting rod assembley...
HI, I've got another question about my new to me '63 Johnson Seahorse 10 HP model QD-24. After changing the lower unit oil(which there was only about an ounce or two in the lower unit), I was having trouble getting it to shift, so I took off the cover plate on the exhaust housing where the...
Hi, I've got a 1963 johnson 10 HP seahorse model qd-24. I'm going to change the lower unit oil. On the side of the lower unit, it says "fill with hypoid oil". Besides buying a hyopid oil, what else should I look for? Is there a specific viscosicity I need to use, or are all hypoid oils the...
I recently bought a 10 HP, 1963 Johnson Seahorse, model QD-24. I pump the primer bulb, and the glass fuel filter bowl fills up with gas. It starts and will idle ok in a large garbage can with water. The problem I have is that the glass fuel bowl will go to almost empty (maybe 1/4" of fuel in...
