Hey guys was wondering if you could help me out with this strange problem. I have a old. 2stroke 15hp johnson that i can start by pumping the priming ball to fill the bowl but once the bowl is empty is dies. Carb will not suck anymore fuel in.
ive took the carb apart twice. Needle is not...
I have a couple of questions about converting a outboard thats setup for controls to a tiller.
I currently have a 1990 20hp johnson (tiller) and there is a 1983 60hp johnson for sale locally (controls) that im considering purchasing. I was wondering if maybe the tiller parts from the 20hp could...
Well i hit a tree with the prop on my 6hp today and it snapped a blade right off. So now i need a replacement and im wondering where i should be looking me go to place online doesnt carry a prop for it. Thanks
I have a 1990 johnson 20hp that I've upgraded with a 35hp carb and intake. Well yesterday I took it out and at WOT on my 14ft alumicraft it would do 28mph, I was out there working on a leaking gas line and when I got it fixed I ran it with the hood off to see if it was still sucking air and it...
I was wondering if someone could point me in the direction of a high pitch prop than offered from the factory. I am currently running a solas 10x15 pitch alum prop on my modified johnson 20hp and it plains instantly so I assume I could bump up to a higher pitch for more top end speed. I bought a...
Built a jack plate the other day for my 1965 Johnson 6hp. The jack plate raised the motor 7 inches and at that height you have to be moving to prime the water pump which was my biggest concern. Turns out the water intake wasn't the biggest problem its my loss of speed.
I'm guessing the prop...
I was wondering what were the possible causes of a outboard cutting out only on deacceleration?
I have a 90 20hp Johnson that I put a bigger carb and intake on and it runs great except for the fact that it cuts out when coming down from WOT. Idles prefect and runs great on the way up to WOT...
This sound right (RPM'S)
So had my boat out today for the first time after getting it fully converted from a johnson 1990 20hp to a 35hp. So I didn't use my tech before on the stock motor but it did 25mph and with the intake manifold change it did 29mph, now with the new carb is only does 32mph...
So I thought I was having issues with my heat sensor so I went and bought a IR thermometer at the advice of a forum member and it turned out to be that the sensor was working fine and the motor was getting to hot.
Replaced the thermostat, head cover gasket and put a new impeller in it and it's...
When converting a Johnson 20hp to a 35hp I understand the biggest two components are the intake manifold and carb off a 30/35 model. Since a 35hp carb seems to be next to impossible to find is there other carbs that would work? Maybe the same throat size but just need different jets?
Well found out today that the temp sensor in my head (1990 johnson 20hp) is forcing the motor into slow mode. Water coming out of the tale tell does not appear to be hot and I find 45 bucks to replace this sensor extremely high for what it is. Since this is a new to me motor I'm gonna put a...
Well after some advice on here I pulled my carb back off a really really cleaned it: acetone, boiling soapy water, ultrasonic, and more acetone.
So got out on the water with it today and it was still coughing a little but this time the idle screw cleaned it right up. So now I thought the motor...
I have a 1990 johnson j20cresb 20hp and I think i'm having some timing issues, got this motor with some of the throttle linkage missing and a bent prop. Replace prop and bracket and than it would die on acceleration and coughs at idle speeds. Rebuild carb and fuel pump and running a clear fuel...
I was wondering if anyone knew how much water a 64 johnson 6hp could pump an hour or minute. Or maybe a good way of testing it? Thinking about changing where the water is picked up on the motor using some welding, hoses, and a pump. The pump could pick up water right off the bottom or back of...
I have a 1990 Johnson 20 HP that I bought as a project. Replaced the throttle linkage bracket that was missing and got a prop on it and put a carb rebuild kit in it. Yes I thought I can finally get this thing on the water.
So was on the water for the first time today with this motor and it will...
