Hi everyone, I recently got a V20 1986 dualC

Yes it is worth something to the person that really wants one, I removed mine and went railless.


Rusted pieces, it's now a parts motor. Don't worry about them. Maybe scoot some oil on them, just because.

The motor may or may not be set on the backsplash, depending on the best performance location. That's normal.


Looks like Marine Tex should fix these.


And as far as for this

Here is your special paint

Here is a better picture of the serial # plug. This is on a 75hp Mariner.


Well maybe not the Mariner (I can't remember) but you get the idea.

MERC URY has a welch plug in the block and there should be a metal tag on the port side of the pivot bracket I believe with the numbers. I'll try and get out tommorrow and snap a few pics of the tag locations on my old parts engine I have. The XRI's started in 89 with the 2.4L's, but that one looks like a 2.5L to me. I see the oil injection module on it, but no oil tank. Guess somebody rigged it up to keep the self test horn and water in fuel alarm. That rust in your pictures isn't major compared to some of the salty dog engines as those parts are just regular steel. TSUBAKI them pics of the welch plug you posted are of an OMC, you can tell by the OMC M stamped in it. That 200 is a good engine when it's running, but they are one of the fuel thirstiest 200 pigs ever built. The 200 XRI's are said to be 240HP LASER engines with a 200 exhaust tuner. You could always pick up another 200 carb motor and transfer the injection over to it.

Is that a 1 piece cowling? didn't they start in 93? my steering arm has a lot more rust than that, but i am going to change it out this winter.........

[THEFERMANATOR]

I believe all of the XRI's had 1 piece cowlings. Seen a 90 before with original 1 piece cowling instead of the clam shell.

Cool. im getting an idea on what to do with each part. thanks

The person i bought this boat from told me that they burned this engine because they forgot to put OIL in the fuel tank.?

so CARB more economic on gas than EFI?

[THEFERMANATOR]

They each have there finer points. The EFI system is slightly easier cold starting, and tends to idle and troll better without loading up as bad. Carbs are said to be slightly better at cruise for milage. The EFI is quite a bit smoother compared to carbs IMO, and the throttle response is UNREAL!

This is cylinder #2 after being run at 100:1. This was on a boat I bought with the engine this way(A 93 150 XR6)

Found this one tonight, though you may be interested in the 4 bolt tune-up option.
