Outdrive: replace the u-joints, replace the gimbal assembly, replace the impeller and ensure that the housing around the impeller is still OK (no corrosion, cracking, etc.), inspect o-rings and seals present in upper and lower, inspect all bellows (and probably replace them-especially if they are the originals). In addition to the unit, I'd check the shifter assembly to make sure it moves freely and is not corroded into one position or difficult to move due to corrosion.
The u-joints and gimbal may not necessarily require replacement, but I'd do it while I had it all apart. From what I recall, these parts are not horribly expensive on an A-1. I'd also pull the prop and inspect the shaft and the seal on the shaft to make sure they haven't been damaged by corrosion, fishing line, etc.
Seems that the most common problems on these units are leaky seals, impellers, gimbal, u-joints, leaky bellows, and shifter/shifter cable problems.
Good luck. I'm sure some of the more mechanically knowledgeable guys will add more.
I haven't gotten around to checking out the A-1 yet, but I'll probably replace the U-Joints.. they're cheap enough (about 45$, for each actual u-joint... its 410 for the whole u joint assembly, including the shafts, etc). ... The gimbal assembly wont be getting replaced (List : $1215, I found it for $972)... I'm not going to spend more on that one thing than i spent on the entire boat. I'll probably check out, and maybe replace the gimbal bearing (67$), and inspect the bellows (also pretty cheap).. and def replace the impeller (i think the whole kit to rebuild it is like 44$). I'll also check all the o-rings I can find and replace as many as I can.
Does anyone know if automotive gaskets are the same as marine gaskets, or if there is any difference at all? The closest marina to me is about 2 hours away, and if i can pick these babies up at the local parts store, that would be great. (im talking engine water pump, thermostat housing, exhaust manifolds.. obviously nothing specific to marine stuff (sterndrive).
Thanks!
