Fuel pick up,

Could you inform me on the fuel baffle float what baffle float I should have in my pick up tube, I see you there are two options one with two contact points in the middle or two on each side. Which is four contact points on the baffle float. see photo below with the 2 contact points in the middle What is the difference

They work the same, one is just an older part.

The white one with the 2 magnets in your picture is the newer design.

Question, Do the the oil injection pumps feed oil through the crank shafts if not how does the oil circulate through the rotary valve chambers back to oil tank, just trying to understand how the oil system works.

 

[jts32]

The oil injection and the RV chamber are basically two separate entities, fed from the same oil tank. The injection system supplies oil that mixes with the fuel, and lubricates the crank, pistons, and cylinders. The RV chamber is just a flooded cavity. It is gravity fed, and doesn't circulate

Hi could i ask you about the water flow regular valves, we spoke about these a little while ago as my ones are missing on my Seadoo speedster 787 2 stoke jet boat which you mentioned if the boat is running ok then dont worry about refitting them and one the members said i should put them on the boat as these are required, i have two questions, one, the boat buzzer did continually go off on the water, but was fine on the trailer also the temp sensors are broken and not connected so i guest i was wanting to know what this could be and what you think i should do, the other think is the wires for the sensors were loose around the engines and if they touched metal could that sent the buzzer off.

Second is the 1999 Seadoo speedster 787 jet boat ment to have the two fuel cut off as my boat does not have them.

Also i have tryed to hunt down the correct plumbing for the water flow raves if i was to install then as per the original
