OSD Popoff & Jet Pump Tester (60 psi)


This tool is a must have for tuning any pwc or jetboat that uses Mikuni SBN carburetors. Since weíve found these can be expensive from Mikuni, weíve decided to build and offer this heavy duty more economical unit. We're sure you think itís easy to build one of these but thatís not the case. We get the parts to build this from at least 4 different sources. If you have plenty of free time, you could hunt around and put one together or consider saving you some time and effort with ours. Itís built with new non corrosive all brass fittings and a new high quality gauge. Once assembled, every unit is partially submerged in water to insure no leaks are present.

This unit can be used for pressure testing and properly setting Mikuni popoff and also works well for checking your Sea Doo jet pump after an oil change to make sure the seal and o-ring are ok. Setting popoff correctly is an important step when rebuilding any Mikuni SBN Carburetor and helps avoid problems once out on the water. For testing popoff, this specs page and this tuning page should provide all the info needed. For testing your pump, you apply some pipe sealant to the threads then install the adapter in the cone fill opening. Then connect the pumps hose and pressurize to 5 psi. If it holds for a minute without dropping, your pump is ok.

  • Easy to read gauge from 0-60 psi (Note Gauge might differ in brand and design from one pictured)
  • Includes a 1/8 npt brass hose barb for testing Sea Doo 2 stroke pumps too!
