Best thing I’ve done, more power, better fuel economy and I don’t have to worry about the bloody riser gaskets ever again.

Fitted some a while back. Out on the water now with them and all going great!

I received the manifolds and they are beautiful. The detail and workmanship is excellent. I also thought it was unique that you thought to include studs to hang the manifold on to ease the installation of the manifold bolts.

I unboxed and fitted up my new set of sbc / Indmar 320 risers onto my 2007 Malibu Wakesetter…bolted up no issues using the supplied gaskets and bolts using the custom bent spanner to tension the bolts . My pipes were modified with another water inlet elbow for the standard “balance“ hose , so it’s 100% hosed up as it left the factory. Can’t thank Mark, Jeremy and Sam plus the team MarineTorq enough for the pipes and the custom addition. If you need a new set, grab a set off MarineTorq you won’t be disappointed.

Boat is running very well and the SS manifolds certainly run at a much cooler temperature, cool to touch when running whereas the OME cast iron were too hot to touch.

Just fitted a set onto a customers V6, easy to fit, look great and no need to worry about engines filling up with water! Best thing you can buy for your I/O boat engine.
