Ok, I have been cruising this forum for long enough! am looking for some even more technical support than I have already found. I'm just a college kid who likes to tinker with anything I can get my hands on, no detailed knowledge or work experience, other than spending all my free time on the water. I basically rebuilt a Sears Gamefisher but in the end, time ran out, project failed, but I learned alot.
To the chase, I just aquired a 1970 Johnson Seahorse yesterday and look forward to putting it on my 13ft duck hunting boat. The owner said it was rarely used by her aunt (freshwater only) and then it sat in a barn for 10 years and then 3 years ago she paid a mechanic $300-400 bucks to get it running and then it sat in her warehouse eversince.
I began my tinkering early this moring and found much new hardware, fuel pump and revamped carb. A part of the throttle system was siezed up and I eventually "fixed it" but I also need a new throttle handle because the old one it rotted and slips everyonce in a while. It has great looking sparks and lower unit oil. I took off the cylinder cover and broke the seal on the headgasket (should I replace before running? I've got some silicone greese to put on it) just to check out the cylinders and water cooling area. The cylinders looked great to me, and the rest had minimal flaking that I somewhat wiped off. There was some sand in the water jacket and I tried to blow most of it out. I have not checked the impeller but I plan on finding it tommorow and ordering another when I order the new head gasket. I have already ordered the owners manual and plan on fueling with 40:1 ratio of 87 octane gas and what oil? I also drained the leftover fuel in the lines and have not come close to starting it, what should I look out for before I get it running? Thanks, Tyler
