I was wondering this motor doesn't turn very fast if I just jump the solenoid with a battery would that cause it to not want to spark or have any compression my compression checker hardly moved at all
Ok, that's a little concerning. How slow is slow? The flywheel should be completely revolving 3 or 4 times a second with the starter. If you are getting less than 2 turns a second, it's going to have a very hard time starting. Do you have another battery that you can use to rule that out? Just because your bilge pump is running, doesn't mean your battery is good. Jump it to your car if you need to. Get the starter spinning well so we can move on to the compression.
The compression is the main concern here. You should be getting some kind of reading. First thing is that I would check your gauge in something that runs normally like your lawnmower. Make sure it's working properly.
Ideally, you want that motor north of 120 psi per cylinder, but at that age 110-115 isn't uncommon, and anything above 100 should give you a reasonably good running motor. Even if the starter is turning really slow, you should be getting a reading of some kind. Now since we don't know when this motor last ran, the compression check will be a starting point. It'll likely go up a little after the motor's been used for a bit and the cylinders get lubed back up.
A couple of notes when testing compression:
1) remove the kill switch lanyard to kill the spark to the plugs.
2) remove ALL of the spark plugs to reduce the work the starter motor needs to do, this will also help to increase the starter speed
3) Move the throttle all the way to wide open. This reduces the vacuum that will also reduce the compression reading
4) Engage the starter until you get a couple of turns of the motor without the gauge increasing in pressure. (Shouldn't take much more than 5 or 6 turns of the motor to get there)
Good luck!
One last comment: I would at least pull the lower unit and check the water pump. The PO can tell you he changed it, but it's so critical, I don't take anyone else's word for it. Especially if it was done "Last year", as that is easily mis-remembered. If it is in poor condition, you can toast your motor and that 20 minutes you saved by taking the PO's word for it means you need a new motor.
