Re: mercruiser replacement drive ?
The SEI warranty is outstanding, 3 years - NO FAULT. You will not find that anywhere else. The only complaint I have heard is that the paint quality is not as good as Merc. You can have that drive repainted many, many times for the price difference.
I am running an SEI lower on my boat an have no complaints at all, except that I bought it too soon. I only got a 1yr warranty. Oh well, it was still less expensive than a reman unit.
I am planning for more power which mean I will need to re-gear. I have decided that I will purchase a new SEI upper and sell the old Merc upper(in perfect condition). Based on what my damaged lower sold for, I hope to get most of the cost of the new unit back.
One more note - Mercruiser changed the speedometer connector on the top of the lower unit sometime after '96. Your new drive will have the new style connector, so you will need to change the connector on the hose on your boat. I think the price of the connector was $6.40 when I did mine.
