Congrats on getting the boat, it's a good stable running hull for its size, and these old 200s are about a foot longer than newer 200s, being 20'9" long, vs 19'8" for some of the newer models.
Once you get it on the water there a few things to pay attention to that will help make the drive system work better and last longer. One thing is for a Cobra to shift properly, the idle has to be between 500-600 rpm in gear, on the water, don't depend on the dash tach, they are often inaccurate. I use a Actron tach/dwell multimeter to set mine. The other is that it must not jump out of gear after shifting, if so get it back to them right away because the clutch dogs in the lower unit will wear out and that's a real expensive repair. The condition of the transom shift cable and the adjustments of the shift system is critical to the longevity of these units. When I first got mine it would shift into gear ok but would not come out of gear to neutral. I took it to the best OMC shop around and they got it shifting great. That was back in 2004, since then all I have had to do is maintenance. I take the drive off in the fall, check the bellows for water and check the gimble bearing and ujoints. Then in the spring I check the whole shift linkage and lube all the pivot points with OMC triple guard grease. There is a bell crank in the pivot housing that can get deposits packed in behind it, you have to clean that out and grease it so the shift cable can move the bellcrank up and down, which is what shift the gears in the lower unit. Finally make sure the ESA system works, this is an electronic device that lowers the engine rpm when shifting from gear to neutral, to allow the clutch dogs to release. It won't have to engage if you test it running it on land because there is no resistance on the gear set from the prop being in water, but in the water you may feel a slight drop in rpm when shifting to neutral from foward or reverse, this is normal. If this is not working right it may be hard to shift to neutral which is dangerous esp when docking. Just a few things to check out.
I will and thank you for all your advice.
