Header Installation
Great care should be taken when installing headers onto the engine. The cylinder heads
are made of aluminum and the threads could strip if bolts are misaligned or over-tightened.
Begin by loosely installing all the hardware and then draw the header in evenly by going
over all bolts several times. Final torque should be 25 ft lb.
Tailpipes for a standard Bravo set-up are available directly from ILMOR Marine Engines
under part number MVP 0152. Custom tailpipes are to be obtained directly from CMI.
Care must be taken to provide adequate clearance between the tailpipes and the transom.
If the tailpipes do interfere with the transom they can put excessive load into the header
causing cracking, premature failure and possible engine damage.
The headers provided with the MV10 connect to tailpipes with CMI 4-1/2" sweeper flex
flare clamps available from CMI, ILMOR Marine Engines or any ILMOR authorized service
center.
MV10 tailpipe clamps are available for purchase from any of the following:
• ILMOR Marine
• CMI
• RG RAY

jumper, hose clamps, gasket, t-bolt & nut)
