it looks like an early 80's crossflow. I believe it weighs just under 400lbs. There are alot of parts around yet

[wideopen23]

I think that is a little closer to mid to late seventies. I had a 1976 Erude 200 that looks just like that. If you need anything let me know I still have the motor out in the garage. I blew up the lower end. So I bought a newer motor.
But everything from there up is still in good shape. I have 235 carbs on it if you are intrested.

Get a model number, and I'll look it up.

40 mph seems a little slow. What size boat is it on?

Before you buy it, stick a hot battery in it and do a compression test.

[EMDSAPMGR]

I agree with the compression check. Should run about 90 lbs each cyl. These engine suffered from early failure of the top ring. Piston ring groove too high on the piston, and would fail when used with today's gasolines. If a ring lets go, will take out the head. Good news is that there are tons of parts avail for this engine. Engine is 149 cubic incher. This is a high-port engine like the 235, but without the bubble exhaust. Makes it's horsepower at higher rpms. Not much out of the hole, tho. They typically came with 235 carbs, but only the 150/175 heads. Could really use a set of 235 heads to help holeshot. Looks to be in decent shape for it's age.

I don't think the 235 came out til 78, my 77 200 came with yuk carbs. They sent me a new set that worked fine, so it could be the carbs.

[WATERWINGS]

Could be only running 40 MPH, cause the speedo pick-up looks broken off. :eek:

[Forkin' Crazy]

I think most 200s came with 235 carbs.

EMDSAPMGR, you are talking about '79 or earlier 235 heads, right?

I still don't understand the "high ring thing". I have had two high ring motors. One has been rebuilt with std. low rings because it was worn out. The other has never had a cylinder head off. I always run 92-92 octane, good oil and have never slung a ring off. BTW I am building another high ring motor next month.

[illMATTic]

thanks for the info. that would be slick if he was just an idiot and was realy going 65 when it said 40. i think im going to wait till the snow melts to pull it out of its spot. motor and boat are only 800 bucks. its a 20' checkmate.

How can the 76-77 200s have 235 carbs when 235s came out in 78?

[EMDSAPMGR]

Has The Engine Manufacture Date Been Determined? The Pull-over Jet Carbs First Came Out On The 78 200-235's. By 79 Omc Had Gone To The Hi Ring Groove Pistons And The Factory Originals Crapped Out On My 200. The Omc Replacments Had A Lower Top Ring. Yes On The 235 Heads.

[neveredge]

The 78 235 carbs were the biggest carbs made for any crossflow from the factory. They are not the same carbs as the 200 hp model and they are bigger than the later carbs found on the 2.6 235 and 2.6GT/XP.

The heads on a 78 235 were also the best small bore crossflow heads from the factory with the exception of the CCC/RS race heads. These heads were also on an earlier 200, not sure if it was the 76 or 77 model.

Hope this helps.

[76baja18ft]

the early 200's(76-77) used 1 5/16" carbs,, the 235's had 1 3/8".. my 76 model 200 still has the small carbs

[baja200merk]

If you dont like him you can tell him that means the motor is tired and chew him down more lol

They didn't, but......

Most of the 200s had 235 carbs....Because they made more 200hp engines inbetween '78 and '84 then they did in '76 and '77. :)

BTW still waiting on a model number.....

[neveredge]

The 78 235 had larger carbs than the later 1 3/8 th's carbs that came on the 235. I'm not sure of the exact size.

I was under the impression that 1 3/8" were the largest. From what I understand, the best carbs were the later '84 2.6 XP/GT carbs, and they are 1 3/8.

[neveredge]

The 78 235 carbs are bigger than the 1 3/8ths carbs. They were only produced for 1 year. If Racer would chime in I'm sure he can set us straight on the exact size.

[kubelwagonman]

1 5/16's this was the size

[neveredge]

Those are the small carbs, I'm not sure what was actually stamped on them but when you measure them they are larger, like 1 7/16+.

I wish I had a set but from what I've been told they don't work well for general boating but were quite sought after by the old crossflow drag racers back in the day.

If anyone has a set please measure them and let us know the size. I will look up the part #'s this weekend and post them.

Racer or Wilber Weeks could clue us in also.

[Riverratt]

I thought I remember 1 7/16" or were they the carbs available from land and sea?

I think the L&S carbs were 1 25/32" or something crazy like that.... which is close enough. :) From what I understand, the venturi was large enough to where they didn't work well on a heavy boat at all. A lot of bog out of the hole. I had a chance to buy a set once, but opted to buy more 1 3/8" sets instead.
