The PTT motor runs CW and CCW depending on which way you want to trim the motor.
There are usually two types of PTT motors. One has a ground in the center of the motor winding. That is a 3 wire motor. Power on either of the two outer windings turns the motor CW or CCW. These use solenoids...
Obviously the bolt cannot protrude below the steering cable, or it will hit the transom.
Are you against getting the arm from the motor to the steering cable? You may not have the correct range of steering without it.
Alternatively, get a long bolt that fits the steering arm. using some nuts, fasten the steering cable a few inches below the steering arm, so the tube is parallel to the transom.
I think that mounting will give you issues. All you need is a rod on the steering arm that projects a bit downward a couple of inches. That would allow you to mount the tube parallel to the top of the transom.
It is common to have a rod between the steering cable and the steering arm of the...
If you can put the old motor back on the transom and launch the boat. Now walk to the transom (you are 250# right), or get your son to add his weight and see how much she lowers in the water.
You want the transom solid. If she flexes at all she will gradually weaken over time. Auto hatch supports ate therefore a bad idea. The top of the transom is where the most strain will occur under power. That is where you need the reinforcement.
A 19 footer often will have a HP rating near 150.
SEI may make one for your motor. Those early V6 motors sometimes had the small diameter 4-1/4" gearcase. Not sure you can get one of those, but the larger gearcase 4-3/4" may fit your motor. You would need a new prop for the larger gearcase.
Rectifiers are easy to test with an ohmmeter. They should have continuity (zero resistance) one way, and no continuity (infinite resistance) the other way.
Assuming you have a 3 wire Mercury rectifier, it is really a 4 wire standard bridge rectifier where the 4th wire (-DC) is ground. Measure...
Seal the edges of the decking with resin. That will be fine.
Drill and fill the screw holes with silicone caulk, before installing the SS screws.
The plastic hatch will allow walking on it, until the sun weakens it.
When you take the gearcase off, check where the shift rod goes thru the shift cover. Those covers can corrode and swell grabbing the shift rod tightly, causing the shift linkage to give and not allowing the motor to shift into forward easily.
If the insulation is still good, you could recover it with new plastic to keep the pieces contained. use some heavy trash bags cut to fit and some spray on adhesive.
Alternatively, there is an insulation which looks like silver bubble wrap. It would be fastened with the same spray on...
As long as you detect a signal, you are probably good, as they either work or don't.
Not sure you can see a half sine wave on a voltmeter. Try the AC setting on the voltmeter and step it down in voltage until you get something.
