You are extremely lucky... if it won't start close to shore, the last thing you want is to get it started and then go out a long way on the water and have it quit on you!

Bad spark plugs / Fuel mixing...

You may have leaking crank seals. If they leak they can cause air to mix with the fuel before it gets to the carb, causing the motor to rev high unexpectedly.

It is oil injected and if it has been sitting for a long period of time the oil will seep into the intake. This is common on older watercraft. When you get it initially started it will make a huge cloud of smoke and take a few minutes to clear up( burning the excessive amount of oil)

It is fairly easy to change your starter bendix. Just start by disconnecting the battery cables. Then you will remove the bolts on the flywheel cover, which also hold the starter in place, and then just change the old part out with the new one.
