225 HO Lower Unit Gearcase Issue

Hello everyone,,

I need some help on what direction to go with replacing the gearcase on my 08 E-Tec 225 with the L2 lower unit.  It has around 350 hours on it.  Rebuilding it will not work.  For one, It has a bulge on the outside of it. The engine has always been garaged so it can't be freeze damage so it must have overheated to cause a bulge like that.  I discovered the bulge while wiping it down after filing it up with fresh HPF Pro that I have changed religiously since I purchased the engine new.  The used oil was not burnt.  Two, BRP has superceeded the L2 with the heavy duty M2 gearcase so I don't think I could get a new L2 gearset.  Anyway the housing is warped and they don't sell those anymore..  On the Evinrude website a new gearcase is $6089.25 not counting a conversion kit they reference plus installation. So, a new gearcase is out of the question.  A new G2 would be nice.  Maybe next year.  What are my options?

Re: 225 HO Lower Unit Gearcase Issue

Overheating a gearcase will not cause a bulge, only internal damage or freezing would do that. Because a gearcase runs submerged in water, it is likely never to totally overheat but something like a bearing failure could cause a localized hot-spot internally.

Talk to your Evinrude dealer as he can order a factory approved rebuilt M2 gearcase through the Genuine Parts and Accessory Catalog that Evinrude puts out.
