I just acquired a 2001 90ELPTO Serial# OT299540 to replace a 50ELPTO on my Triton 175 Sport aluminum boat. The 50 has had the oil injection bypassed by just removing the oil lines and plugging them (bought it that way). I trying to decide if it makes sense to delete it on the 90. If I do I plan on removing the pump and shaft and doing a cover plate but I've read on many threads that they aren't prone to failure like some of the others were. What say you BBC?
