Re: 1960 75hp super sea horse
I'd try to start it first, just so you know what you're dealing with. Use fresh, clean gas, mixed 32/1 with 2stroke oil. I'd take a look at the lower unit grease first, if you intend to run it any length of time. Make sure you pull the right screw - I think that design has a screw down there that's actually the pivot for the shift yoke, if you pull that one out, you have to pull the lower unit apart to fix it.<br /><br />The lower unit has to be in the water when you run it, even for a few seconds, or you'll burn out the water pump. The lower has to be well down into the water, not just to the lower unit - midsection junction.<br /><br />Assuming it starts, first you'll want to check that it's pumping water, internally. Ideally, you want to put a new impeller in it, and if not, you want to watch the temp like a hawk until you do put an impeller in it. That motor should have an overheat light on the dash, check that it's working - ask us how if your manual doesn't say. When warmed up, the block should be good and warm, but not hot - we say you can rest your fingers on it for 2-3 seconds without getting burned.<br /><br />Shift it back & forth a few times, and let it fast idle in gear for a while. If the grease looked OK when you checked it earlier, it's OK to take a run around the lake for a bit, see if she heats up or runs badly under power. In either case, after you pull the boat out, recheck the lower unit lube & see if it got milky from water intrusion. <br /><br />Have fun!
