Resolved the spark issue with a new power pack and running at 5100 rpm on the tiny tach under load. All seems to be well in my world for now but I’ll still probably have a look at the cylinders here soon to see what there is to see.
When everything was running well I am happy to report I was getting 4900 rpm with 3 people and the 13 1/2” x 15 prop.
I see now from the Top Secret folder in Johnson outboard repair that I did the compression test wrong. My engine was cold and I cranked it from the ignition. I have developed a...
I can’t find find any 13 1/4” x 15” props anywhere. There are some stainless ones going for mid $300’s but that’s a little out of my budget at the moment. I’ll carry on double checking my motor isn’t having issues before I bite the bullet on that.
I don’t know much about props but I’m assuming...
I powered the one that came with it and it was not very loud but it did look crusty. I’d still prefer a light though so I might experiment, if it’s just grounding out a switch when it gets to temperature and sending 12v then I’ll probably just hook it up to a light.
Thanks for the tip on the thermostat, first thing I did was put an impeller on when I got it. It did actually have an over temp buzzer on the dash harness when I got it but figured it was useless because of how loud the old thing is. I don’t know how but I was going to maybe just replace the...
Hi all, I have never had a tach on my boat until recently and have found that rpm at WoT is low for my motor (is: 4800 should be: 5200). I wanted to consult here to see if anyone thinks my prop is causing this issue or if I need to be looking at the powerhead. I was wanting to get another prop...
Glad I came across this thread because I usually leave the winch rope on when backing in. My ramp doesn't have a dock and I’m scared it will get away from me so I’ll probably back it in less and motor off the trailer from now on.
Went out boating this past Saturday by myself to do some on water carb tuning trying to get my engine running right (low rpm at wot issue) and also just to waste a day where I’d normally probably be sitting around on my phone. Better to do nothing in particular out on the water than on the couch...
