I am about to take the plunge into 4-stroke territory for the first time. Old thinker when it comes to outboards, I like 2-strokes because there are a lot less moving parts. I don't trust oil injection because I know it can fail. I don't have a choice on the Opti as mentioned. I did take the oil infection off the 1998 EFI Mercury and a 60 Mercury and a 90 HP Johnson and numerous V-6 Mercury Outboards. The downside to taking off the oil injection is the motor smoked noticably more at idle. Oil injection leans the ratio out at idle so the motor smokes less as I understand it. Without a load the motor doesn't need as much oil to remain lubricated, so it saves you in the wallet, until it stops working and then POP goes the weasel...On second thought, I might get along just fine with the 4-strokes after all.. Doesn't feel like I have been holding onto much now that I decided to let go.. They have proven to be fantastic in economy and longevity. Stay 4-stroke or let that be a chit to be used to bargain for a better sale price, the re-power angle..

If you buy a boat with ANY engine that old, don't put much value in the engine. Most of the imports have rock solid oil injection systems since they were smart enough to use all metal gears for the pumps VS MERCURY's IDIOTIC idea of a nylon crank gear like on the 2.0, 2.4, and 2.5's. When it comes to DFI engines, I wouldn't want one out of warranty. Most all of them require expensive computer software to do much of anything to them, and even a small repair can get up over $1K pretty easily. I would hold out for what you want if it was me, and not settle for one unless your getting a SMOKING deal on it. As for removing the oil inejction, on the bigger engines most all of them had good systems except for EVINRUDE. If it is a regular EFI, you can safely remove the oil inejction, but as you pointed out DFI's MUST have it on them. Carbed engines may require a rejet if you remove the oil inejction as they tend to load up at idle without it.

My goal is to find one with a 4 stroke, or to repower with a 4 stroke, but if that smokin deal comes along and my money is not right to upgrade right away I just wanted to know what to avoid.
Seems from what the experts say, stay away from out of warranty DFI.
