Hello All,

Please help..

This is my last ditch effort. I cannot find any info online and all the local boat shops begin stuttering when I start asking questions.

I have been given a barely used and garage kept 1984 river boat that has a 1984 Johnson 140hp jet. This baby has been winterized (gas drained and dry)and I would like to get this baby fired up without dragging it to the lake to work on getting it running.

Can someone tell me if this motor has a flush port. I have found some info that it is supposed to be on the left side of the lower. The only thing on the left side is a zerk fitting and a accordian boot looking device next to it. Other than that…there is nothing or any screws that would accept a flush fitting..

I can certainly provide the Serial Number if needed.

Well, I’m guessing the jet drive unit is an aftermarket add on piece. Perhaps you can post some pictures…

Well crap, I was hoping to avoid dragging this thing to the lake everytime I needed to start it for Spring fire up or a tuneup…Oh well, the whole boat and motor was an awesome gift so I cant complain too much…thanks

On their site it sounds like it isn’t VERY hard to switch back and forth between a regular lower unit and the jet attachment. Maybe you can find a "donor" motor? Is the jet a big plus for you?

Just looked on ePay. Whoa! All the initial hits for a LU were $300-400!!!

If you want bad enough just remove the jet unit. then put a hose on the water tube. you can run the motor.
