Hi everyone, I recently got a V20 1986 dualC

[hardboiled]

great thanks all.

I found some outboards on craigslist, will any of these blocks fit the one i have? I will take a picture of the engine block to show you all the hole it has on the block side.

this one doesnt look like the engine i have http://miami.craigslist.org/mdc/boa/835511868.html

This looks alot like the same model i have

With every engine manufacturer there will be subtile or gross differences in powerheads of the same horsepower, given the year models.
The possibility exists that the foot may be interchangable more readily than the powerhead.
Each one is not running, you should be able to find one that runs for $1500.

Looking to see what years might be interchangable, found one with your same problem.

So far it looks like "92-"99's are the same.
Other than being either carburated or fuel injected.

91+ 2.5L's will all interchange easily. You could even pick-up a 150 OPTIMAX and bolt onto it. If you get the right poppet set-up installed in it, you can also use the earlier 2.0L's and 2.4L's. The 2.0L's, 2.4L's, and 2.5L's all use the same bolt pattern on the mounting surface. EFI or carb makes no difference. The exhaust tuners did change depending upon which HP engine or size you have. As well as changes in the cooling pressure and flow depending upon the displacement. 91+ 2.5L's are pretty plentiful as they tend to be thirsty and most are updating there power. BIGSHRIMPIN has ALOT of parts that will fit that mid section.

BUILDERFL recently picked up a complete late model 2.4L for cheap that needed switchboxes. He took the parts off his old one and was back on the water for under $1K.

Here's his thread.

more pics
Is this thing worth anything? i took it off from the other 73'/v20 i had, it looks like new.

this piece is badly rusted



this looks ok?who knows? me ?i dont know.

is this suppose to lean to the transom or goes like this

scratch i talk about before

Do i need to sand the whole the bottom and paint it again or with gelcoat alone is enough?
Trailer galvanize crossbar frame getting looking very rusted, Can i sand it and use some special paint?

Here the hole on the block




I was told the engine was a 92' not sure.

Just remember if you going to buy a different motor to use, You need a 20" shaft!!

FERM, where are the model/serial #'s on these things?
Do you have pictures of them and the freeze plug looking thing with the numbers stamped in them?
hard, just as soon as we can get you to post pictures of the motors serial/model #, we can tell you what year it is.
Quite possibly this is it.

hard, either take a picture of the numbers on this shiney round plug or write them down and give them to us (if that is the serial # plug).

[tsubaki]

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.
