Omc 140hp cross flow

[Jimmybar]

Good spit, just looked up marine exhaust , to get a visual on your ideas , yep lots of options, you may have started a roll here,, now if you got some pics of exhaust systems straight off the exhaust ports , This could be what I'm looking for to go v6, keep em comin,,,,,,

[Jimmybar]

I love this , gets you thinking

Somewhere I have seen that diagram of your system, OMC paper I believe.

Somewhere pictures are posted of that system, was it you who has them?

You need a kr style and mount it upsidedown.

Its is possible ,to make the v4 a screamer , but let's look at repower , the engine block is a crossflow , " we all no dat" but other engines have the same base pattern like 200 v6 , , and possibly a 90 degree 175 v6 looper of the same vintage thats 91 to 98 , question is ,, do these 90 degree loopers fit the cross flow base , if they do , then that's exciting , is there anyone ,,who can throw some light on this , ..???

[Schramer]

The loopers have a different bolt pattern but you could find a V-4 looper and adapter and bolt it right up to your current setup, with the correct hardware. Being that the out-drive is a jet, you don't have to worry about the X-Flow gearcase holding up to the looper. As long as your rig has the possibility of changing the adapter plate, you should be be able to pull it off I dn't know shizzle about jet drives so I could be way off but with an outboard, it is a very doable swap.

Gez chad , one thing I'll hand to ya , you step up to the mark , I'll do some home work , thanks mate ,

[Jimmybar]

Went through parts lists , on v6 includes ,cross flow v6 ,and 90 degree looper , your right Chad all loopers have different base adaptor to cross flow, barking up the wrong tree ,I was , , , at least I can mount a v6 on the turbojet , or just be happy with the four , thank you for clearing that up ,

I didn't know if you had a the ability or not, to change the plate on your rig. The midsection was the same for several years between the X-Flow & looper and you can mount any V-6 to almost any mid throughout the years with the correct adapter plates/gearcase. They were different between the two but I have a bad ass V-4 (small) looper case with a 2:1 ratio, that has a V-6 prop shaft fit into it & have ran it with success on the V-6's.

I have a nice V-6 X-Flow MOD that I was finishing up to sell but it is complete and I'm sure, if you were interested, you would want the powerhead only.....understandably, if you could make it work with your setup. Want it to go to a good home as I consider it a relic lol

this is the limitation , unless you add an adaptor plate between engine and this , you would also need to extend or remanufacture drive connector , gets messy , a cross flow v6 would bolt on , just don't throw to much gas down the exhaust hole ,

You need to mod the bubble back to allow the exhaust to exit straight out and not go down to the adapter then build the rest as well.

It doesn't stop there , then , the drive is 21t 21t , omc cobra top gearbox set , gear to 21 t 19t to take advantage of extra hp , nah, going to back away from this one , stick with the v4 , nice dreamin,,

hot v4 will never break those gears IMHO

That's a fact, if its one thing that's solid in a turbojet ,,the gearbox , the gears arrangement, to take advantage of hp ,increase impeller shalt speed buy selection of gear sets , 21;21 , 21; 19 , or 18 or 17 , 16 , , sport jet do a 90 hp to 240 hp on the same hull , you can never have enough hp , that seems to be the problem for "old petrol heads" l"200 v6 crossflow , 21;19 gears, water cooled expansion chamber directly off the exhaust chest , this coming together , is there any v6 exhaust chest bolt-ons out there , that would could put the project on the board , ??pics would be awesome , were probably dreaming here , or do we make our dreams come true , thanks for your input to date , its inspiring,

[Jimmybar]

How bout this one ,,!,,,!,, still looking for a suitable manifold idea ,
