inline 6 hp & year

[danny9696]

Hi all I just bought an inline 6 with a SN#3024893, the guy said it was a 150 hp but it does not seem to match up with anything I find for a 150hp, anyone have any advice on this please. It has the same thunderbolt ignition as my 115 hp but it did not have power trim/tilt everything else maches up 100%

Thanks for any help on this

It's not a 150.
It could be a 1970 135 or a 1971 115.

I had the same corncern over an engine I bought with 1500 decals. I did not want to take off the transfer covers so I verified that the carbs were WMK 22 (s) which only came on the 1500.

If your 1150 has KD carbs it will have either KD-6A or KD-6B the 1350 had KD7A or KD 7B

If your 1150 has WMK carbs it has either WMK 3,10,15,18,26,28,32,36,40,41.

If your 1350 had WMK carbs it had WMK-4.

Hope this helps you. JR

Re: inline 6 hp & year

Thank you all for your input, next question is, my carbs are KD 1, can some one cross this to a modle and hp!

Also I have a 1975 115hp 1150 with WMK 18 carbs, can I run them on this other engine? What ever it is!

I am lost I hope some one can bring light to the end of my tunel I need to order some parts but I need to know what to order for!

Thank you all

KD 1 was used on 1968/69 125 hp

Might work but I would used those carbs who belonged to the engine, IF you decides to try.... at least switch main jets .

But beware that the 1968/69 and 1975 engine are two different constructions .

• The early 125 are a Crossflow engine without any exhaust tuning .
• The later 115 are a "Direct Charge" engine ( next steep on the evolution from the crossflow design ),and since 1973 (1972 on the 140 hp ) it does have a exhaust tuner

I am lost I hope some one can bring light to the end of my tunel I need to order some parts but I need to know what to order for!

Your carb number does not match your serial number, obviously someone have mix/matched some.... got any pictures ?? front and bouth sides .

Are there any number stamped in on your block ( startboardd side )

Re: inline 6 hp & year

Wow you really have a mess. I would talk to the jerk who sold you this and ask him WTF??????

#1 If the block is silver, (it should be from yer posts thus far) you should look for a casting name. None = 1350 or 1150 1970 or later. Does it say "Typhoon" or "Tiger"???

#2 The serial number on the silver blocks are up near the starter flange.

#3 I own 2 99 cubic inch 1250(s) and they don't have ANY exhaust tuners, while my 2 90 cubic inch 1000(s) do.

#4 If this power head is a 1250 and was swaped to a 1350 or 1150 midsection as it appears I don't know if those engines had exhaust tuners, (I think they may have). If so that is gonna be another issue with the 1250 carbs on God knows what block you have.

What a mess. Ya need a private detective fer this upside down deal.

My overpriced $.02. JR

Edit: since ya claim to have a 115 that matches the detail of the "150" you bought it must be an early 1970s silver block or you are smokin' something. Does yer 115 or I should say 1150 have an exhaust tuner in the mid section? Does the engine you purchased? Seems like a problem to me.

Edit #2 Now that I reread yer next post HOW COULD YER BLACK BLOCK 1975 1150 match, (100%) the 1250 or 1350 silver block???? Didn't you notice the SIGNIFICANT difference in color and fuel systems?????? I'd talk to the person you bought this engine from. Hope ya didn't pay too much fer it.

Re: inline 6 hp & year

Both blocks are black, the 115hp 1150 I have is a 115hp! no questions on that one, the one I bought two weeks ago is the one in question, It is a black block I have not had time to check for any numbers on it, the guy I bought it from had it given to him, it does not have power trim or tilt and as far as I can tell matching up parts it looks to be a true 68-69 125.

If it is a 125 can i put that on my 115 mid section? and was it a good engine in its time?

Also not sure what an exhaust tuner is, this is my first time with these engins

Thank you for your help

The 1968-69 1250 was a silver block (that someone could have painted to be cute I suppose, [dunno why they would go to the trouble but stranger things could have happened, and probably have happened]).

The 1250 has old slyle twin fuel pumps on the side of the block that are very different from the single fuel pump system on yer 1975 1150 (or a 1400 or a 1500 fer that matter).

BTW: The blocks prior to 1971 0r 1972 do not bolt up to the later mid sections or visa versa so it is likely a painted silver block.

It is possible that 1250 carbs could have been put on a 1150 or a 1350. If they were jetted properly fer the application it could werk fine, (the big guns on this site would know the answer to that riddle), which is above my pay grade n' knowledge level.

If it is a 125 can i put that on my 115 mid section? and was it a good engine in its time?

If it is a 1968 0r 1969 silver block that was painted: NO. If it is a 1973 or later black block: YES, (unlikely due to the changed bolt pattern and the serial number you provided at the start of this thread). The 1250s were great engines, (I have two of 'em).

Also not sure what an exhaust tuner is, this is my first time with these engins

Go to a site with complete online parts catalog, (you will need to do this to figure out what yer FrankenMerc is anyhoooooo). Check the mid section picture from the online parts catalog fer yer 1975 1150 and your will see what an exhaust tuner is. (Try the sites listed at the sticky thread at the beginning of this section.)

The 1250s didn't have 'em yet my two 1969 1000s do, (the 100 hp engines were a smaller block [90 cubic inches] instead of the 100 cubic inch blocks we are talking about here).

Not sure if the 1350 had 'em, or the early 1970-71 silver block 1150 either (which can be made into a 1350 with carbs and maybe reeds), but all the black blocks I have owned have had them.

Thank you for your help

You are welcome, glad to help out. JR
