Had Pressure test done before I changed seals and o’rings. Guy said it held all night. Go figure, but I was getting water in. The bubble test sounds good, at least it’s something I can see. What do I use? Tube, gauge, stater valve ? How much air pressure?
There are a few way to get air in. The adapter from the Lu oil pump bottles came in very handy.
New driveshaft is 200.00 I was leaning in that direction. I see now there is supposed to be a heat shield over the control wires leading to the lower unit. We’ll see if that is available. I’ve got time, won’t see hard water here till about Thanksgiving.
This sat for 4 days, it’s better. I’ve got the parts ordered.
Well, replaced driveshaft, plate under water impeller, top driveshaft seal/ again, and added heat shield to control wire. Yesterday was 85 in MN. Took her out for a good test run. Gear lube looks good, not perfect but better. I’m going to stop with this lower unit before I break it. I’ll switch over to a finished project post. Might take me awhile to put it together. This is the prop that was on the motor. Had some damage, local shop repaired it. Between that and the new driveshaft. I’m trying to imagine less vibration. Might be in my head because of what it cost me.
The leading cause of vibration is propeller damage. Now that I had it refurbished it’s better. I’m not going to change the prop. Engine isn’t lugging or over revving. No tach on this thing
Oh, you have calibrated Tachometer Ears...
The muffler belt is fine
