I've been piecing together a little fishing outfit off Craigslist. I now have a Lowe 1232 and a 4hp 1969 Johnson 2 stroke outboard. I've seen plenty of YouTube videos with this combo that has the boat up on plane and running about 15mph with a similar load in the boat. I'm a pretty big guy and have a trolling motor and battery up front which puts my load load at about 300lbs, but I thought I would at least be able to hit 10mph and get it on plane.
The best I could manage today was 6mph. I tried all 4 positions on the manual trim as well as moving the battery forward and backward to play with the weight distribution.
So when it was running today, it seemed to run fine but had no power. It didn't seem like it revved very high at full throttle like my 2 stroke dirt bike did. But it did seem like it was a linear progression in response to the throttle.
When I got it home, I pulled the engine cover. Everything looks fine and in good condition. I pulled the spark plugs and they looked brownish-gray with no carbon buildup.
The engine is model # 4W69B. I also bought a new 3 gal tank and new fuel line, both from WalMart (3/8" line with bulb). When I bought it, the guy had it in a tank and demonstrated it. It smoked a bit because he had some SeaFoam in his fuel. It seemed to run fine. It's a clean looking engine and the guy fixes them up as a hobby.
I had a canoe with a 50 ft lb thrust trolling motor that would hit 5 mph. So something seems wrong! What should I look at first?
