I think it's braised not welded

Hi I'm after a standard engine x member for a 1200. will need to be posted to cairns, at my cost of course.

Thnks in avance.

sorry flood clear mode. if the engine floods you put your foot flat to the floor, tps reads 100% and wont inject fuel to clear the flood.

You can use no tps BUT you wont be able to use flud clear mode witch can be a pain in the arse.

I am but fortunately I'm not in sydney anymore :)
what exactly are you wanting to look at?

I have not seen a a12 marine manifold but would imagine water is mixed before it exits the the manifold hence why it would need replacements.

In turbo marine engines the mixer is a pipe that introduces your raw water (sea water) into your exhaust after the turbo for muffling, cooling and an exit for your raw water. there are a few things to be considered when setting this up.
#1 exhaust angel: you must have a vary steep exhaust angel after the turbo as you don't want water draining back into your exhaust ports.
#2 aqua lift and or flapper valve: an aqua lift is a great muffler and will stop water being forced back up the system on deceleration and reversing. the flapper valve will just help prevent water going up the exhaust.
i personally would keep away from the jet ski stuff and use a direct drive with a soft clutch.

no point in adapting the mercruser manifold, intake would be in the way and the spacing is way off and they are #OOPS#! if you are turbocharging you would be better off making a mixer after the turbo or just wrap the pipes and dump the exhaust over the transom. what drive system are you going to use?
