I have a 1989 Johnson 150hp v-6 running premix. How low should the compression be before I decide that the motor is just too worn out to keep putting money into it? A mechanic told me my boat has already reached this point. My compression for all cylinders are from mid to high 70's with none...
I have a 150HP outboard that runs great on earmuffs but will not run well in gear on the water (under load). The problem is that I don't have a trailer or a car large enough to tow this. I have to pay $220 for a hydralic trailer to put in and another $220 when I take it back out of the water...
My outboard isn't going to run any more this year (and maybe not ever again). I have about 40 gallons of premixed fuel in the boat's gas tank. Is there any problem with using this premixed outboard gas in my truck? Its a 2002 GM V-6 with fuel injection. I'm thinking of dilluting it by using...
I have an 1989 Johnson 150hp VRO V-6 on a 21 ft walk-around cuddy. The crankcase no longer delivers enough vacuum pulse to properly run my VRO fuel pump. My VRO pulls enough gas to keep the carb float chambers full when I run at 2500 rpm or less. Higher rpms result in gas starvation. If I...
When you squeeze the gas line primer bulb, are you providing unmixed gas to the carbs?
Another question: Say your vacuum pulse becomes reduced due to a faulty vro air pump, or due to an excessively worn engine that produces weak vacuum pulses from the crankcase. You have a friend pump the...
Does anyone know the gas tank sizes for this model (has a Johnson 150 VRO engine). It has a huge metal gas tank below deck. I'm thinking about 50 gallons. Does that sound about right?
I have a 1989 Johnson 150hp VRO on a 21' walk-around which needs a new fuel pump. I'm thinking this might be a good time to go to premix. My replacement VRO pump is #5007420 and the no oil premix pump is part # 5007422. I expect that the premix replacement pump will be an easy install using...
I have a 21' Chris Craft Sea Hawk with a Johnson 150. Its been running great all season, but all of a sudden it won't run above 2500 RPM wide open. If I squeeze the primer ball or if I engage the choke, it takes right off. When I release the choke, the boat slows back down to 2500 RPM. Its...
Hi,
I have a 1989 Johnson 150 outboard V6. I've changed the gas line filter and have disconnected the gas and oil lines at various points, squeezing the primer bulb to insure that there are no line restrictions. The VRO horn still blows steady above 2500 RPM and quits when you back off...
