I just bought a 1993 Stratos 280 SF with a 150 Johnson V6 Silver Star Series outboard (Model VJ150ELATG). The previous owner just had it in the shop and had fuel pump replaced with one that uses the fuel/oil mix instead of the separate fuel and oil model. He also replaced some O rings. Not sure what else he did - it was about $900 in service. He mentioned that the mechanic initially told him that he would need to get the carbs cleaned since it was idling poorly. After the service, he cranked it and said it didn't seem to be idling poorly anymore.
So I've taken it out twice and here's what I'm seeing.
1) It takes a while to crank. I will prime and choke and it just takes quite a while to get it to even attempt to turn over.
2) after idling for a bit, then accelerating, it would die. It takes several attempts to get it to engage without stalling.
3) at high full throttle, the motor misfires? or something and the motor kicks up due to the boat speed and lack of thrust holding the motor down. The motor doesn't die, just stops for a split second then keeps running at top speed.
4) The water from the water pump isn't coming out in a stead stream, It's more like a spray. Not sure if that's normal or not.
5) After running then sitting with the motor off, it takes a while to get it to crank again. Killing for a short time doesn't have this problem.
I read that it could be water in the fuel - I pumped out about 5 gallons of the ~15 left in the tank and didn't see any water. Based on what I read, didn't seem like water was the issue, but I could be wrong.
I also read that it could either be the carbs need cleaning, the water pump needs work and/or the spark plugs need to be replaced. Just looking for some advice on what could potentially be the problem and what I can do to test/fix it. I am handy, just haven't really worked on outboards before, but certainly not afraid to try.
Thanks in advance!
