Re: 3 hp Sea King (Gale?)
That motor has an unusual water pump. It's in front of the prop. Instead of a vaned impeller, it has a rotor (#550040). There's an eccentric on the propshaft that wiggles the rotor around and squeezes the water up into the powerhead. They're a very simple and durable design, but not very efficient. If you can find a new rotor, you should replace it. They shrink over time and get hard. Then they don't pump too well. Unfortunately they haven't been made in quite some time and any old stock will have shrunken and hardened as well. I got around that by machining a larger eccentric. If you get spray out of the ehxaust, you'll be okay.<br /><br />The gearlube I believe is called 104...it's either a very heavy oil or a very thin grease maybe a mixture. Lubrimatic may still offer it. You can use gearlube. Check it often, keep a drip pan under it.<br /><br />The magneto appears to be the same good old magneto they used for decades. Parts for that should be no problem. Other available parts would be sparkplugs, shear pins, recoil springs...that's about it. <br /><br />If you can post the model number I can probably give you a year, but I'd say it's a 1958 (mod. GG-8962A).<br /><br />The white knob is for adjusting the carb mixture. They were rather crude and needed constant attention. I don't see a choke knob, so turn the knob to the left to start (richen the mixture), and turn it to the right as the motor warms-up. Fuel ratio 24:1, but you'd probably be fine at 32:1.<br /><br />Have fun with it.
<br /><br />Sorry for rambling on, but also, what does the little white knob toward the bottom of the motor do? <br />
