Sounds like a weak battery or corroded cables or connections. Be careful using that starting fluid, it doesn't have any lube oil in it.

Definetely watch the dry starts with ether(starting fluid). A friend of mine had a rough starting 9.9 gamefisher and he always used starting fluid to start it. premature wear on the rings due to dry starts ultimately lead to low compression and he ended up burning the motor up

Yeah starting fluid is just a bad bad idea poor practice.. motor fires hard and blows the reeds the wrong way with a backfire, metal fatigue and then one day the motor may/will suck a reed through the intake. Best case is the reeds just won't seat properly and you'll replace them before you suck em. Stariting fluid is just a bad idea. PERIOD. Sounds like a weak starter/cables/arm here easy enough to fix w/o ether.

I don't recall seeing ... did you check for corrosion on all your cables and connections? I'm inclined to think that the problem is electrical rather than mechanical. Reason being you said that the engine turned over fine with all plugs removed. If there was a mechanical problem then the engine would bind, with or without the plugs being in. So if we eliminate the mechanical then we are left with the electrical. That makes the prime suspect corrosion... either in the connections or in the cable itself. Easy enough to check, just run a jumper cable from your battery to the starter and try to start it. If it still binds, then you can eliminate the cables as part of the problem and move on to the next check which should be either a weak battery or a bad starter. Again, easy to check. Just remove your trucks battery and use it to replace your boats battery, then try to start it again. If it works the problem is the battery, if not, then you probably have a starter problem. (If you have one, find out what the draw is for your starter, then connect an amp meter on the cable and see how many amps you're pulling. That should tell you right away if your starter is good or bad)

Spare, may have just hit it. Take the lower unit off. The lower may be holding you up here . You should be able to rope pull a 90hp easy enough even one with brand new compression. As for starting fluid lose it and just mix up some premix in a spray bottle, much better for the motor.
